Cyber Scene #1 |
This addition to the Newsletter is intended to provide an informative, timely backdrop of events, thinking, and developments that feed into technological advancement of SoS Cybersecurity collaboration and extend its outreach.
The Center for Cyber and Homeland Security at George Washington University (GWU) hosted its Annual Strategic Conference on 3 May 2016 focused on “Public-Private Sector Coordination on Cybersecurity.” Across multiple sessions, a swath of public sector leaders as well as US intelligence community “titans”—former heads of CIA’s Counterterrorism Center, the National Counterterrorism and Counterintelligence Centers, and present DHS officials—combined engaging presentations with vibrant Q & A exchanges open to the public and captured live by CSPAN. This session also included foreign audience participants and French embassy officials, following up the French Minister of Interior Cazeneuve’s 11 March GWU presentation on the heels of this year’s Paris attacks. Among other pressing issues, one panel predicted an upturn in the public’s interest in cybersecurity due to lawsuits against private sector companies deficient in providing sufficient cybersecurity—and attendant US congressional and judicial response to define and regulate such legal action.

As SoS outreach continues its transoceanic direction, the view on US private-public sector from the UK’s thoughtful Economist is enlightening. In 16 April 2016’s article entitled “Encryption and the law: Scrambled regs,” The Economist casts the present situation as a cold war heating up and putting “America’s technology firms on a collision course with its policemen and spies.” It too looks at US Congressional activity as well as the implication for US domestic rules that leave “the truly dangerous” using more robust software written overseas.

Hot research in cybersecurity fuels HotSoS 2016
The 2016 Symposium and Bootcamp on the Science of Security (HotSoS) was held April 19-21 in Pittsburgh, PA at Carnegie Mellon University. Researchers from multiple academic fields came together for presentations demonstrating methodical, rigorous, scientific approaches to identify, prevent, and remove cyber threats. A major focus of the conferences was on the advancement of scientific methods, including data gathering and analysis, experimental methods, and mathematical models for modeling and reasoning.
Bill Scherlis, co-PI for the Carnegie Mellon Lablet, was conference co-chair. Introducing the event, he called for participants to interact and share ideas and thoughts and to ask questions about the nature of security and the nascent science that is emerging. Stuart Krohn, the initial program manager for the Science of Security initiative at NSA, welcomed the group. Noting the government’s long-term interest and commitment to their work, he challenged them to continue to address cybersecurity using strong scientific principles and rigorous methods. Four outside speakers addressed Science of Security from the perspectives of consumer interest, government policy, and industry, and on the value of a large graph method of analysis. Research papers, presentations, tutorials, and poster sessions rounded out the agenda.
Lorrie Cranor, CMU professor on loan to the Federal Trade Commission (FTC), addressed “Adventures in Usable Privacy and Security: From Empirical Studies to Public Policy.” Topics of interest to FTC are quantifying privacy interests, q disclosures, financial technologies, attack trends, improving complaint reporting, tools to automate tracking, targeted advertising, cross device tracking, fraud, and emerging scams. “Good warnings help users determine whether they are at risk,” she said, but “people ignore poor warnings that put the onus of calculating risk on the end user.” She described a study that shows that password expiry is counterproductive.
Greg Shannon, CMU professor currently working at the White House Office of Science and Technology (OSTP), spoke on the science challenges in “Trustworthy Cyberspace: Strategic Plan for the Federal Cybersecurity Research & Development Program” issued in February 2016. In the plan, OSTP is looking at the science and technology issues that affect policy and the policy issues that impact technology. The keys to addressing the problems, he said, include the creation of a Commission on Enhancing National Cybersecurity, a Federal CISO to take lead on policies, oversight, and strategy, budgeting a $3.1 billion IT modernization fund and working with industry to encourage broader use of security tools such as multi-factor authentication. The plan’s goals are to counter adversaries’ asymmetrical advantages; reverse those asymmetrical advantages; achieve science and technology advantages to achieve effective deterrence; and meet the long term goal that cybersecurity research, development, and the operations community will be able to quickly design, develop, deploy, and operate effective new cybersecurity technologies and services; that cybersecurity tasks for users will be few and easy to accomplish; and that many adversaries will be deterred from launching malicious cyber activities.
Christos Faloutsos, Professor of Electrical and Computer Engineering at CMU, spoke on “Anomaly Detection in Large Graphs.” Citing recent research from several projects, he demonstrated the value of using graph theory to identify patterns that are otherwise hidden. Motivating his research are the problems of identifying such patterns for fraud detection and patterns in time-evolving graphs/tensors. He uses Hadoop to search for many clusters in parallel, starting with random seeds, updates sets of pages and like times for each cluster, and then repeats until convergence is achieved. This approach has been deployed at Facebook as CopyCatch where it was determined that most clusters—77%— come from hard to detect real-but-compromised users and that easier to detect fake accounts are only 22%. For E-Bay fraud detection, the technique has been used on the non-delivery scam. Using NetProbe allows detection of the scam by identifying the groups of people who are cross rating each other to appear honest. The fraudulent nodes look trustworthy. His conclusions: patterns and anomalies go hand in hand; large data sets reveal patterns/outliers that are otherwise invisible.
FireEye’s Matt Briggs gave “A View from the Front Lines with M-Trends.” In corporate cybersecurity, he said, continuing trends show that spear phishing remains the most common entry point and that most hacks are leveraging trust relationships to get in, especially leveraging IT outsourcing. New trends are described as “David v. Goliath:” the rise of business disruption attacks that are politically motivated, cause data leaks to embarrass the company, are financially motivated, and produce the destruction of critical systems. His “good news” was that in the last five years the median number of days before discovery has been reduced from 416 days to 146.
Tutorials about ways to add rigor to relatively soft data analysis were provided. The first, “Systematic Analysis of Qualitative Data in Security” was given by Hanan Hibshi, Carnegie Mellon University. Her tutorial introduced participants to Grounded Theory, a qualitative framework to discover new theory from an empirical analysis of data. It is useful, she said, when analyzing text, audio or video artifacts that lack structure, but contain rich descriptions.
Tao Xie, University of Illinois Urbana-Champaign, and William Enck, North Carolina State University, presented the second tutorial, “Text Analytics for Security.” Researchers in security and software engineering have begun using text analytics to create initial models of human expectation. In this tutorial, they provided an introduction to popular techniques and tools of natural language processing and text mining, and shared their experiences in applying text analytics to security problems.
Nine research papers were presented on studies about intrusion detection, threat modeling, anomaly detection, and attack variants. Thirteen posters were also offered. The HotSoS 2016 Proceedings will be published by ACM and available online at the ACM Digital Library available at: http://dl.acm.org/. Abstracts of the tutorials, papers and posters are available with their Digital Object Identifier in a companion document.

Hui Lin, Homa Alemzadeh, Daniel Chen, Zbigniew Kalbarczyk, Ravishankar Iyer; “Safety-critical Cyber-physical Attacks: Analysis, Detection, and Mitigation Optimal Thresholds for Intrusion Detection Systems.” DOI:http://dx.doi.org/10.1145/2898375.2898391
Abstract: Today’s cyber-physical systems (CPSs) can have very different characteristics in terms of control algorithms, configurations, underlying infrastructure, communication protocols, and real-time requirements. Despite these variations, they all face the threat of malicious attacks that exploit the vulnerabilities in the cyber domain as footholds to introduce safety violations in the physical processes. In this paper, we focus on a class of attacks that impact the physical processes without introducing anomalies in the cyber domain. We present the common challenges in detecting this type of attacks in the contexts of two very different CPSs (i.e., power grids and surgical robots). In addition, we present a general principle for detecting such cyber-physical attacks, which combine the knowledge of both cyber and physical domains to estimate the adverse consequences of malicious activities in a timely manner.

Aron Laszka, Waseem Abbas, Shankar Sastry, Yevgeniy Vorobeychik, Xenofon Koutsoukos; “Optimal Thresholds for Intrusion Detection Systems.” DOI:http://dx.doi.org/10.1145/2898375.2898399
Abstract: Intrusion-detection systems can play a key role in protecting sensitive computer systems since they give defenders a chance to detect and mitigate attacks before they could cause substantial losses. However, an oversensitive intrusion-detection system, which produces a large number of false alarms, imposes prohibitively high operational costs on a defender since alarms need to be manually investigated. Thus, defenders have to strike the right balance between maximizing security and minimizing costs. Optimizing the sensitivity of intrusion detection systems is especially challenging in the case when multiple interdependent computer systems have to be defended against a strategic attacker, who can target computer systems in order to maximize losses and minimize the probability of detection. We model this scenario as an attacker-defender security game and study the problem.

Atul Bohara, Uttam Thakore, and William Sanders; “Intrusion Detection in Enterprise Systems by Combining and Clustering Diverse Monitor Data.” DOI:http://dx.doi.org/10.1145/2898375.2898400
Abstract: Intrusion detection using multiple security devices has received much attention recently. The large volume of information generated by these tools, however, increases the burden on both computing resources and security administrators. Moreover, attack detection does not improve as expected if these tools work without any coordination.
In this work, we propose a simple method to join information generated by security monitors with diverse data formats. We present a novel intrusion detection technique that uses unsupervised clustering algorithms to identify malicious behavior within large volumes of diverse security monitor data. First, we extract a set of features from network-level and host-level security logs that aid in detecting malicious host behavior and flooding-based network attacks in an enterprise network system. We then apply clustering algorithms to the separate and joined logs and use statistical tools to identify anomalous usage behaviors captured by the logs. We evaluate our approach on an enterprise network data set, which contains network and host activity logs. Our approach correctly identifies and prioritizes anomalous behaviors in the logs by their likelihood of maliciousness. By combining network and host logs, we are able to detect malicious behavior that cannot be detected by either log alone.

Jeffrey Carver, Morgan Burcham, Sedef Akinli Kocak, Ayse Bener, Michael Felderer, Matthias Gander, Jason King, Jouni Markkula, Markku Oivo, Clemens Sauerwein, Laurie Williams; “Establishing a Baseline for Measuring Advancement in the Science of Security – an Analysis of the 2015 IEEE Security & Privacy Proceedings.” DOI:http://dx.doi.org/10.1145/2898375.2898380
Abstract: In this paper we aim to establish a baseline of the state of scientific work in security through the analysis of indicators of scientific c research as reported in the papers from the 2015 IEEE Symposium on Security and Privacy.
To conduct this analysis, we developed a series of rubrics to determine the completeness of the papers relative to the type of evaluation used (e.g. case study, experiment, proof). Our findings showed that while papers are generally easy to read, they often do not explicitly document some key information like the research objectives, the process for choosing the cases to include in the studies, and the threats to validity. We hope that this initial analysis will serve as a baseline against which we can measure the advancement of the science of security.

Bradley Potteiger, Goncalo Martins, Xenofon Koutsoukos; “Software and Attack Centric Integrated Threat Modeling for Quantitative Risk Assessment.” DOI:http://dx.doi.org/10.1145/2898375.2898390
Abstract: Threat modeling involves understanding the complexity of the system and identifying all of the possible threats, regardless of whether or not they can be exploited. Proper identification of threats and appropriate selection of countermeasures reduces the ability of attackers to misuse the system.
This paper presents a quantitative, integrated threat modeling approach that merges software and attack centric threat modeling techniques. The threat model is composed of a system model representing the physical and network infrastructure layout, as well as a component model illustrating component specific threats. Component attack trees allow for modeling specific component contained attack vectors, while system attack graphs illustrate multi-component, multi-step attack vectors across the system. The Common Vulnerability Scoring System (CVSS) is leveraged to provide a standardized method of quantifying the low level vulnerabilities in the attack trees. As a case study, a railway communication network is used, and the respective results using a threat modeling software tool are presented.

Antonio Roque, Kevin Bush, Christopher Degni; “Security is about Control: Insights from Cybernetics.” DOI:http://dx.doi.org/10.1145/2898375.2898379
Abstract: Cybernetic closed loop regulators are used to model sociotechnical systems in adversarial contexts. Cybernetic principles regarding these idealized control loops are applied to show how the incompleteness of system models enables system exploitation. We consider abstractions as a case study of model incompleteness, and we characterize the ways that attackers and defenders interact in such a formalism. We end by arguing that the science of security is most like a military science, whose foundations are analytical and generative rather than normative.

Zhenqi Huang, Yu Wang, Sayan Mitra, Geir Dullerud; “Controller Synthesis for Linear Dynamical Systems with Adversaries.” DOI:http://dx.doi.org/10.1145/2898375.2898378
Abstract: We present a controller synthesis algorithm for a reach-avoid problem in the presence of adversaries. Our model of the adversary abstractly captures typical malicious attacks envisioned on cyber-physical systems such as sensor spoofing, controller corruption, and actuator intrusion. After formulating the problem in a general setting, we present a sound and complete algorithm for the case with linear dynamics and an adversary with a budget on the total L2-norm of its actions. The algorithm relies on a result from linear control theory that enables us to decompose and compute the reachable states of the system in terms of a symbolic simulation of the adversary-free dynamics and the total uncertainty induced by the adversary. With this decomposition, the synthesis problem eliminates the universal quantifier on the adversary's choices and the symbolic controller actions can be effectively solved using an SMT solver. The constraints induced by the adversary are computed by solving second-order cone programmings. The algorithm is later extended to synthesize state-dependent controller and to generate attacks for the adversary. We present preliminary experimental results that show the effectiveness of this approach on several example problems.
Keywords: Cyber-physical security, constraint-based synthesis, controller synthesis
Carl Pearson, Allaire Welk, William Boettcher, Roger Mayer, Sean Streck, Joseph Simons-Rudolph, Christopher Mayhorn; “Differences in Trust between Human and Automated Decision Aids.” DOI:http://dx.doi.org/10.1145/2898375.2898385
Abstract: Humans can easily find themselves in high cost situations where they must choose between suggestions made by an automated decision aid and a conflicting human decision aid. Previous research indicates that humans often rely on automation or other humans, but not both simultaneously. Expanding on previous work conducted by Lyons and Stokes (2012), the current experiment measures how trust in automated or human decision aids differs along with perceived risk and workload. The simulated task required 126 participants to choose the safest route for a military convoy; they were presented with conflicting information from an automated tool and a human. Results demonstrated that as workload increased, trust in automation decreased. As the perceived risk increased, trust in the human decision aid increased. Individual differences in dispositional trust correlated with an increased trust in both decision aids. These findings can be used to inform training programs for operators who may receive information from human and automated sources. Examples of this context include: air traffic control, aviation, and signals intelligence.

Phuong Cao, Eric Badger, Zbigniew Kalbarczyk, Ravishankar Iyer; “A Framework for Generation, Replay and Analysis of Real-World Attack Variants.” DOI:http://dx.doi.org/10.1145/2898375.2898392
Abstract: This paper presents a framework for (1) generating variants of known attacks, (2) replaying attack variants in an isolated environment and, (3) validating detection capabilities of attack detection techniques against the variants. Our framework facilitates reproducible security experiments. We generated 648 variants of three real-world attacks (observed at the National Center for Supercomputing Applications at the University of Illinois). Our experiment showed the value of generating attack variants by quantifying the detection capabilities of three detection methods: a signature-based detection technique, an anomaly-based detection technique, and a probabilistic graphical model-based technique.

Tutorial:
Hanan Hibshi; “Systematic Analysis of Qualitative Data in Security.” DOI:http://dx.doi.org/10.1145/2898375.2898387
Abstract: This tutorial will introduce participants to Grounded Theory, which is a qualitative framework to discover new theory from an empirical analysis of data. This form of analysis is particularly useful when analyzing text, audio or video artifacts that lack structure, but contain rich descriptions. We will frame Grounded Theory in the context of qualitative methods and case studies, which complement quantitative methods, such as controlled experiments and simulations. We will contrast the approaches developed by Glaser and Strauss, and introduce coding theory – the most prominent qualitative method for performing analysis to discover Grounded Theory. Topics include coding frames, first- and second-cycle coding, and saturation. We will use examples from security interview scripts to teach participants: developing a coding frame, coding a source document to discover relationships in the data, developing heuristics to resolve ambiguities between codes, and performing second-cycle coding to discover relationships within categories. Then, participants will learn how to discover theory from coded data. Participants will further learn about inter-rater reliability statistics, including Cohen's and Fleiss' Kappa, Krippendorf's Alpha, and Vanbelle's Index. Finally, we will review how to present Grounded Theory results in publications, including how to describe the methodology, report observations, and describe threats to validity.

Tao Xie and William Enck; “Text Analytics for Security.” DOI:http://dx.doi.org/10.1145/2898375.2898397
Abstract: Computing systems that make security decisions often fail to take into account human expectations. This failure occurs because human expectations are typically drawn from in textual sources (e.g., mobile application description and requirements documents) and are hard to extract and codify. Recently, researchers in security and software engineering have begun using text analytics to create initial models of human expectation. In this tutorial, we provide an introduction to popular techniques and tools of natural language processing (NLP) and text mining, and share our experiences in applying text analytics to security problems. We also highlight the current challenges of applying these techniques and tools for addressing security problems. We conclude the tutorial with discussion of future research directions.

Abstract: We propose an interactive approach where analysts reason about the security of a system using an abstraction of its runtime structure, as opposed to looking at the code. They interactively refine a hierarchical object graph, set security properties on abstract objects or edges, query the graph, and investigate the results by studying highlighted objects or edges or tracing to the code. Behind the scenes, an inference analysis and an extraction analysis maintain the soundness of the graph with respect to the code.

Abstract: The security of software is increasingly more critical for consumer confidence, protection of privacy, protection of intellectual property, and even national security. As threats to software security have become more sophisticated, so too have the techniques developed to ensure security. One basic technique that has become a fundamental tool in static security analysis is symbolic execution. There are now a number of successful approaches that rely on symbolic methods to reduce security questions about programs to constraint satisfaction problems in some formal logic (e.g., [4, 5, 7, 16]). Those problems are then solved automatically by specialized reasoners for the target logic. The found solutions are then used to construct automatically security exploits in the original programs or, more generally, identify security vulnerabilities.

Abstract: Characterizing what makes cybersecurity professions difficult involves several components, including specifying the cognitive and functional requirements for performing job-related tasks. Many frameworks that have been proposed are focused on functional requirements of cyber work roles, including the knowledge, skills, and abilities associated with them. In contrast, we have proposed a framework for classifying cybersecurity jobs according to the cognitive demands of each job and for matching applicants to jobs based on their aptitudes for key cognitive skills (e.g., responding to network activity in real-time). In this phase of research, we are investigating several cybersecurity jobs (such as operators vs. analysts), converting the high-level functional tasks of each job into elementary tasks, in order to determine what cognitive requirements distinguish the jobs. We will then examine how the models of cognitive demands by job can be used to inform the designs of aptitude tests for different kinds of jobs. In this poster, we will describe our framework in more detail and how it can be applied toward matching people with the jobs that fit them best.

Abstract: Secure collaboration requires the collaborating parties to apply the right policies for their interaction. We adopt a notion of conditional, directed norms as a way to capture the standards of correctness for a collaboration. How can we handle conflicting norms? We describe an approach based on knowledge of what norm dominates what norm in what situation. Our approach adapts answer-set programming to compute stable sets of norms with respect to their computed conflicts and dominance. It assesses agent compliance with respect to those stable sets. We demonstrate our approach on a healthcare scenario.

Özgür Kafalı, Munindar P. Singh, and Laurie Williams; “Toward a Normative Approach for Forensicability.” DOI:http://dx.doi.org/10.1145/2898375.2898386
Abstract: Sociotechnical systems (STSs), where users interact with software components, support automated logging, i.e., what a user has performed in the system. However, most systems do not implement automated processes for inspecting the logs when a misuse happens. Deciding what needs to be logged is crucial as excessive amounts of logs might be overwhelming for human analysts to inspect. The goal of this research is to aid software practitioners to implement automated forensic logging by providing a systematic method of using attackers' malicious intentions to decide what needs to be logged. We propose Lokma: a normative framework to construct logging rules for forensic knowledge. We describe the general forensic process of Lokma, and discuss related directions.

Darya Kurilova, Alex Potanin, Jonathan Aldrich; “Modules in Wyvern: Advanced Control over Security and Privacy” DOI:http://dx.doi.org/10.1145/2898375.2898376
Abstract: In today’s systems, restricting the authority of untrusted code is difficult because, by default, code has the same authority as the user running it. Object capabilities are a promising way to implement the principle of least authority, but being too low-level and fine-grained, take away many conveniences provided by module systems. We present a module system design that is capability-safe, yet preserves most of the convenience of conventional module systems. We demonstrate how to ensure key security and privacy properties of a program as a mode of use of our module system. Our authority safety result formally captures the role of mutable state in capability-based systems and uses a novel non-transitive notion of authority, which allows us to reason about authority restriction: the encapsulation of a stronger capability inside a weaker one.

Abstract: In an organization, the interactions users have with software leave patterns or traces of the parts of the systems accessed. These interactions can be associated with the underlying software architecture. The first step in detecting problems like insider threat is to detect those traces that are anomalous. Here, we propose a method to end anomalous users leveraging these interaction traces, categorized by user roles. We propose a model based approach to cluster user sequences and find outliers. We show that the approach works on a simulation of a large scale system based on and Amazon Web application style.

Jian Lou and Yevgeniy Vorobeychik; “Decentralization and Security in Dynamic Traffic Light Control.” DOI:http://dx.doi.org/10.1145/2898375.2898384
Abstract: Complex traffic networks include a number of controlled intersections, and, commonly, multiple districts or municipalities. The result is that the overall traffic control problem is extremely complex computationally. Moreover, given that different municipalities may have distinct, non-aligned, interests, traffic light controller design is inherently decentralized, a consideration that is almost entirely absent from related literature. Both complexity and decentralization have great bearing both on the quality of the traffic network overall, as well as on its security. We consider both of these issues in a dynamic traffic network. First, we propose an effective local search algorithm to efficiently design system-wide control logic for a collection of intersections. Second, we propose a game theoretic (Stackelberg game) model of traffic network security in which an attacker can deploy denial-of-service attacks on sensors, and develop a resilient control algorithm to mitigate such threats. Finally, we propose a game theoretic model of decentralization, and investigate this model both in the context of baseline traffic network design, as well as resilient design accounting for attacks. Our methods are implemented and evaluated using a simple traffic network scenario in SUMO.

Abstract: Software developers use #ifdef statements to support code configurability, allowing software product diversification. But because functions can be in many executions paths that depend on complex combinations of configuration options, the introduction of an #ifdef for a given purpose (such as adding a new feature to a program) can enable unintended function calls, which can be a source of vulnerabilities. Part of the difficulty lies in maintaining mental models of all dependencies. We propose analytic visualizations of the variational callgraph to capture dependencies across configurations and create visualizations to demonstrate how it would help developers visually reason through the implications of diversification, for example through visually doing change impact analysis.

Abstract: Modern frameworks are required to be extendable as well as secure. However, these two qualities are often at odds. In this poster we describe an approach that uses a combination of static analysis and run-time management, based on software architecture models, that can improve security while maintaining framework extendability. We implement a prototype of the approach for the Android platform. Static analysis identifies the architecture and communication patterns among the collection of apps on an Android device and which communications might be vulnerable to attack. Run-time mechanisms monitor these potentially vulnerable communication patterns, and adapt the system to either deny them, request explicit approval from the user, or allow them.

Abstract: Eddy is a privacy requirements specification language that privacy analysts can use to express requirements over data practices; to collect, use, transfer and retain personal and technical information. The language uses a simple SQL-like syntax to express whether an action is permitted or prohibited, and to restrict those statements to particular data subjects and purposes. Eddy also supports the ability to express modifications on data, including perturbation, data append, and redaction. The Eddy specifications are compiled into Description Logic to automatically detect conflicting requirements and to trace data flows within and across specifications. Conflicts are highlighted, showing which rules are in conflict (expressing prohibitions and rights to perform the same action on equivalent interpretations of the same data, data subjects, or purposes), and what definitions caused the rules to conflict. Each specification can describe an organization's data practices, or the data practices of specific components in a software architecture.

Christopher Theisen and Laurie Williams; “Risk-Based Attack Surface Approximation.” DOI:http://dx.doi.org/10.1145/2898375.2898388
Abstract: Proactive security review and test efforts are a necessary component of the software development lifecycle. Since resource limitations often preclude reviewing, testing and fortifying the entire code base, prioritizing what code to review/test can improve a team’s ability to find and remove more vulnerabilities that are reachable by an attacker. One way that professionals perform this prioritization is the identification of the attack surface of software systems. However, identifying the attack surface of a software system is non-trivial. The goal of this poster is to present the concept of a risk-based attack surface approximation based on crash dump stack traces for the prioritization of security code rework efforts. For this poster, we will present results from previous efforts in the attack surface approximation space, including studies on its effectiveness in approximating security relevant code for Windows and Firefox. We will also discuss future research directions for attack surface approximation, including discovery of additional metrics from stack traces and determining how many stack traces are required for a good approximation.

Olga Zielinska, Allaire Welk, and Christopher B. Mayhorn, Emerson Murphy-Hill; “The Persuasive Phish: Examining the Social Psychological Principles Hidden in Phishing Emails.” DOI:http://dx.doi.org/10.1145/2898375.2898382
Abstract: Phishing is a social engineering tactic used to trick people into revealing personal information [Zielinska, Tembe, Hong, Ge, Murphy-Hill, & Mayhorn 2014]. As phishing emails continue to infiltrate users’ mailboxes, what social engineering techniques are the phishers using to successfully persuade victims into releasing sensitive information?
Cialdini’s [2007] six principles of persuasion (authority, social proof, liking/similarity, commitment/consistency, scarcity, and reciprocation) have been linked to elements of phishing emails [Akbar 2014; Ferreira, & Lenzini 2015]; however, the findings have been conflicting. Authority and scarcity were found as the most common persuasion principles in 207 emails obtained from a Netherlands database [Akbar 2014], while liking/similarity was the most common principle in 52 personal emails available in Luxemborg and England [Ferreira et al. 2015]. The purpose of this study was to examine the persuasion principles present in emails available in the United States over a period of five years.
Two reviewers assessed eight hundred eighty-seven phishing emails from Arizona State University, Brown University, and Cornell University for Cialdini’s six principles of persuasion. Each email was evaluated using a questionnaire adapted from the Ferreira et al. [2015] study. There was an average agreement of 87% per item between the two raters.
Spearman’s Rho correlations were used to compare email characteristics over time. During the five year period under consideration (2010–2015), the persuasion principles of commitment/consistency and scarcity have increased over time, while the principles of reciprocation and social proof have decreased over time. Authority and liking/similarity revealed mixed results with certain characteristics increasing and others decreasing.
The commitment/consistency principle could be seen in the increase of emails referring to elements outside the email to look more reliable, such as Google Docs or Adobe Reader (rs(850) = .12, p =.001), while the scarcity principle could be seen in urgent elements that could encourage users to act quickly and may have had success in eliciting a response from users (rs(850) = .09, p=.01). Reciprocation elements, such as a requested reply, decreased over time (rs(850) = -.12, p =.001). Additionally, the social proof principle present in emails by referring to actions performed by other users also decreased (rs(850) = -.10, p =.01).
Two persuasion principles exhibited both an increase and decrease in their presence in emails over time: authority and liking/similarity. These principles could increase phishing rate success if used appropriately, but could also raise suspicions in users and decrease compliance if used incorrectly. Specifically, the source of the email, which corresponds to the authority principle, displayed an increase over time in educational institutes (rs(850) = .21, p <.001), but a decrease in financial institutions (rs(850) = -.18, p <.001). Similarly, the liking/similarity principle revealed an increase over time of logos present in emails (rs(850) = .18, p<.001) and decrease in service details, such as payment information (rs(850) = -.16, p <.001).
The results from this study offer a different perspective regarding phishing. Previous research has focused on the user aspect; however, few studies have examined the phisher perspective and the social psychological techniques they are implementing. Additionally, they have yet to look at the success of the social psychology techniques. Results from this study can be used to help to predict future trends and inform training programs, as well as machine learning programs used to identify phishing messages.

Wenyu Ren, Klara Nahrstedt, and Tim Yardley; “Operation-Level Traffic Analyzer Framework for Smart Grid.” DOI:http://dx.doi.org/10.1145/2898375.2898396
Abstract: The Smart Grid control systems need to be protected from internal attacks within the perimeter. In Smart Grid, the Intelligent Electronic Devices (IEDs) are resource-constrained devices that do not have the ability to provide security analysis and protection by themselves. And the commonly used industrial control system protocols offer little security guarantee. To guarantee security inside the system, analysis and inspection of both internal network traffic and device status need to be placed close to IEDs to provide timely information to power grid operators. For that, we have designed a unique, extensible and efficient operation-level traffic analyzer framework. The timing evaluation of the analyzer overhead confirms efficiency under Smart Grid operational traffic.
Keywords: Smart Grid, network security, traffic analysis

Acoustic Fingerprints 2015 |
Acoustic fingerprints can be used to identify an audio sample or quickly locate similar items in an audio database. As a security tool, fingerprints offer a modality of biometric identification of a user. Current research is exploring various aspects and applications, including the use of these fingerprints for mobile device security, antiforensics, use of image processing techniques, and client side embedding. The research work cited here was presented in 2015.

Abstract: Audio fingerprinting refers to the process of extracting a robust, compact representation of audio which can be used to uniquely identify an audio segment. Works in the audio fingerprinting literature generally report results using system-level metrics. Because these systems are usually very complex, the overall system-level performance depends on many different factors. So, while these metrics are useful in understanding how well the entire system performs, they are not very useful in knowing how good or bad the fingerprint design is. In this work, we propose a metric of fingerprint effectiveness that decouples the effect of other system components such as the search mechanism or the nature of the database. The metric is simple, easy to compute, and has a clear interpretation from an information theory perspective. We demonstrate that the metric correlates directly with system-level metrics in assessing fingerprint effectiveness, and we show how it can be used in practice to diagnose the weaknesses in a fingerprint design.

Abstract: We propose VERA - an authentication scheme where sensitive data on mobile phones can be secured or whereby services can be locked by the user's voice. Our algorithm takes use of acoustic fingerprints to identify the personalized voice. The security of the algorithm depends on the discrete logarithm problem in ZN where N is a safe prime. Further we evaluate two practical examples on Android devices where our scheme is used: First the encryption of any data(set). Second locking a mobile phone. Voice is the basic for both of the fields.

Abstract: In this paper we introduce a novel technique to discover groups of users sharing the same environment: a room, an office, a car. Using a smartphone device, we propose a method based on the joint usage of GPS and acoustic fingerprints, allowing to greatly improve the precision of GPS only group detection. To reach the objective, we use a novel variation of an existing audio fingerprinting algorithm with good noise tolerance, assessing it under several conditions. The method is shown to be especially effective for groups of listeners of audio and audio visual content. We finally propose an application of the method to deliver content recommendations for a specific use case, hybrid content radio, an adaptive radio service discussed in the European Broadcasting Union, allowing the enrichment of traditional broadcast linear radio with personalized and context-aware audio content.

Abstract: Acoustic recordings play an increasingly important role in monitoring terrestrial environments. However, due to rapid advances in technology, ecologists are accumulating more audio than they can listen to. Our approach to this big-data challenge is to visualize the content of long-duration audio-recordings by calculating acoustic indices. These are statistics which describe the temporal-spectral distribution of acoustic energy and reflect content of ecological interest. We combine spectral indices to produce false-color spectrogram images. These not only reveal acoustic content but also facilitate navigation. An additional analytic challenge is to find appropriate descriptors to summarize the content of 24-hour recordings, so that it becomes possible to monitor long-term changes in the acoustic environment at a single location and to compare the acoustic environments of different locations. We describe a 24-hour 'acoustic-fingerprint' which shows some preliminary promise.

Abstract: This paper reported a novel e-nose type gas sensor based on film bulk acoustic resonator (FBAR) array in which each sensor is functionalized individually by different organic monolayers. Such hybrid sensors have been successfully demonstrated for VOCs selective detections. Two concentration-independent fingerprints (adsorption energy constant and desorption rate) were obtained from the adsorption isotherms (Ka, K1, K2) and kinetic analysis (koff) with four different amphiphilic self-assembled monolayers (SAMs) coated on high frequency FBAR transducers (4.44 GHz). The multi-parameter fingerprints regardless of concentration effects compose a recognition library and improve the selectivity of VOCs.

Abstract: Acoustic fingerprinting is the process to deterministically obtain a compact representation of an audio segment, used to compare multiple audio files or to efficiently search for a file within a big database. Recently, we proposed a novel fingerprint named MASK (Masked Audio Spectral Keypoints) that encodes the relationship between pairs of spectral regions around a single spectral energy peak into a binary representation. In the original proposal the configuration of location and size of the regions pairs was determined manually to optimally encode how energy flows around the spectral peak. Such manual selection has always been considered as a weakness in the process as it might not be adapted to the actual data being represented. In this paper we address this problem by proposing a unsupervised, data-driven method based on mutual information theory to automatically define an optimal MASK fingerprint structure. Audio retrieval experiments optimizing for data distorted with additive Gaussian white noise show that the proposed method is much more robust than the original MASK and a well-known acoustic fingerprint.

Abstract: Ultrasonic imaging for fingerprint applications offers better tolerance of external conditions and high spatial resolution compared to typical optical and solid state sensors respectively. Similar to existing fingerprint sensors, the performance of ultrasonic imagers is sensitive to physical damage. Therefore it is important to understand the theory behind transmission and reflection effects of protective coatings for ultrasonic fingerprint sensors. In this work, we present the analytical theory behind effects of transmitting ultrasound through a thin film of scratch resistant material. Experimental results indicate transmission through 1 μm of Al2O3 is indistinguishable from the non-coated cover substrate. Furthermore, pulse echo measurements of 5 μm thick Al2O3 show ultrasound pressure reflection increases in accordance with both theory and finite element simulation. Consequently, feasibility is demonstrated of ultrasonic transmission through a protective layer with greatly mismatched acoustic impedance when sufficiently thin. This provides a guide for designing sensor protection when using materials of vastly different acoustic impedance values.

Abstract: In this paper we present 1-3 GHz frequency ultrasonic interrogation of surface ultrasonic impedances. The chipscale and CMOS integration of GHz transducers can enable surface identification imaging for many applications. We use aluminum nitride piezoelectric thin films driven at maximum amplitudes of 4-Vpp to launch and measure pulse packets. In this paper we first use the contrast in ultrasonic impedance between air and skin to create an image of a fingerprint. As a second application we directly measure the reflection coefficient for different liquids to demonstrate the ability to measure the ultrasonic impedance and distinguish between three different liquids. Using a rubber phantom the image of a portion of a fingerprint is captured by measuring changes in signal levels at the resonance frequency of the piezoelectric transducers 2.7 GHz. Reflected amplitude waves from air and skin differ by factors of 1.8-2. The measurements for three different liquids; water, isopropyl alcohol, and acetone show that the three liquids have sufficiently different acoustic impedances to be able to identify them.

Abstract: We use audio fingerprinting to solve the synchronization problem between multiple recordings from an ad-hoc array consisting of randomly placed wireless microphones or handheld smartphones. Synchronization is crucial when employing conventional microphone array techniques such as beam-forming and source localization. We propose a fine audio landmark fingerprinting method that detects the time difference of arrivals (TDOAs) of multiple sources in the acoustic environment. By estimating the maximum and minimum TDOAs, the proposed method can accurately calculate the unknown time offset between a pair of microphone recordings. Experimental results demonstrate that the proposed method significantly improves the synchronization accuracy of conventional audio fingerprinting methods and achieves comparable performance to the generalized cross-correlation method.

Abstract: Persistent network communication can be found in many instances of malware. In this paper, we analyse the possibility of leveraging low variability of persistent malware communication for its detection. We propose a new method for capturing statistical fingerprints of connections and employ outlier detection to identify the malicious ones. Emphasis is put on using minimal information possible to make our method very lightweight and easy to deploy. Anomaly detection is commonly used in network security, yet to our best knowledge, there are not many works focusing on the persistent communication itself, without making further assumptions about its purpose.

Abstract: The widespread availability of audio editing software has made it very easy to create forgeries without perceptual trace. Copy-move is one of popular audio forgeries. It is very important to identify audio recording with duplicated segments. However, copy-move detection in digital audio with sample by sample comparison is invalid due to post-processing after forgeries. In this paper we present a method based on pitch similarity to detect copy-move forgeries. We use a robust pitch tracking method to extract the pitch of every syllable and calculate the similarities of these pitch sequences. Then we can use the similarities to detect copy-move forgeries of digital audio recording. Experimental result shows that our method is feasible and efficient.

Abstract: In this paper, we describe an approach to accelerate fingerprint techniques by skipping the search for irrelevant sections of the signal and demonstrate its application to the divide and locate (DAL) audio fingerprint method.

Abstract: Our recent research has demonstrated that the frequency domain power distribution of radio-frequency (RF) photoacoustic (PA) signals contains the microscopic information of the optically absorbing materials in the sample. In this research, we were seeking for methods of systematically analyzing the PA measurement from biological tissues and the feasibility of evaluating tissue chemical and microstructural features for potential tissue characterization. By performing PA scan over a broad spectrum covering the optical fingerprints of specific relevant chemical components, and then transforming the radio-frequency signals into the frequency domain, a 2D spectrogram, namely physio-chemical spectrogram (PCS) can be generated. The PCS contains rich diagnostic information allowing quantification of not only contents but also histological microfeatures of various chemical components in tissue. Comprehensive analysis of PCS, namely photoacoustic physio-chemical analysis (PAPCA), could reveal the histopathology information in tissue and hold the potential to achieve comprehensive and accurate tissue characterization.

Abstract: Sensor Pattern Noise (SPN) has been proved as an effective fingerprint of imaging devices to link pictures to the cameras that acquired them. In practice, forensic investigators usually extract this camera fingerprint from large image block to improve the matching accuracy because large image blocks tend to contain more SPN information. As a result, camera fingerprints usually have a very high dimensionality. However, the high dimensionality of fingerprint will incur a costly computation in the matching phase, thus hindering many interesting applications which require an efficient real-time camera matching. To solve this problem, an effective feature extraction method based on PCA and LDA is proposed in this work to compress the dimensionality of camera fingerprint. Our experimental results show that the proposed feature extraction algorithm could greatly reduce the size of fingerprint and enhance the performance in term of Receiver Operating Characteristic (ROC) curve of several existing methods.

Abstract: Improvements in thin-film piezoelectric materials such as AlN and PZT enable piezoelectric micromachined transducers that are superior to existing capacitive transducers. This paper presents the basic design equations, equivalent circuit model, and fabrication processes for piezoelectric micromachined ultrasonic transducers (PMUTs) operating in fluid or air. Relative to conventional ultrasonic transducers, PMUTs have the advantages of small size, low cost, low power consumption, and compatibility with integrated circuit manufacturing methods. These advantages enable PMUTs to be used in new applications such as human-machine interfaces and ultrasonic fingerprint sensors.

Abstract: Recently, we demonstrated that random projections can provide an extremely compact representation of a camera fingerprint without significantly affecting the matching performance. In this paper, we propose a new construction that makes random projections of camera fingerprints scale-robust. The proposed method maps the compressed fingerprint of a rescaled image to the compressed fingerprint of the original image, rescaled by the same factor. In this way, fingerprints obtained from rescaled images can be directly matched in the compressed domain, which is much more efficient than existing scale-robust approaches. Experimental results on the publicly available Dresden database show that the proposed technique is robust to a wide range of scale transformations. Moreover, robustness can be further improved by providing reference scales in the database, with a small additional storage cost.

Abstract: Source recording device recognition is an important emerging research field of digital media forensic. Most of the prior literature focuses on the recording device identification problem. In this study we propose a source cell phone verification scheme based on sparse representation. We employed Gaussian supervectors (GSVs) based on Mel-frequency cepstral coefficients (MFCCs) extracted from the speech recordings to characterize the intrinsic fingerprint of the cell phone. For the sparse representation, both exemplar based dictionary and dictionary learned by K-SVD algorithm were examined to this problem. Evaluation experiments were conducted on a corpus consists of speech recording recorded by 14 cell phones. The achieved equal error rate (EER) demonstrated the feasibility of the proposed scheme.

This modulation can modify the user perception of the touched object and induce the perception of textured materials. In the current paper, an elastic model of finger print ridges is developed.

Abstract: Controlling the surrounding world by just the power of our thoughts has always seemed to be just a fictional dream. With recent advancements in technology and research, this dream has become a reality for some through the use of a Brain Computer/Machine Interface (BCI/BMI). One of the most important goals of BCI is to enable handicap people to control artificial limbs. Some research proposed wireless implants that do not require chronic wound in the skull. However, the communications consume a high bandwidth and power that exceeds the allowed limits, 8-10mW. This study proposes and implements a modified version of real-time spike sorting for wireless BCI [4] that simplifies and uses less computation via an adaptive neural-structure; which makes it simpler, faster and power and area efficient. The system was implemented, and simulated using Modalism and Cadence, with ideal case and worst case accuracy of 100% and 91.7%, respectively. Also, the chip layout of 0.704mm2, with power consumption of 4.7mW and was synthesized on 45nm technology using Synopsys.

Abstract: The successful and widespread deployment of biometric systems brings on a new challenge: the spoofing, which involves presenting an artificial or fake biometric trait to the biometric systems so that unauthorized users can gain access to places and/or information. We propose a fingerprint spoof detection method that uses a combination of information available from pores, statistical features and fingerprint image quality to classify the fingerprint images into live or fake. Our spoof detection algorithm combines these three types of features to obtain an average accuracy of 97.3% on a new database (UNESP-FSDB) that contains 4,800 images of live and fake fingerprints. An analysis is performed that considers some issues such as image resolution, pressure by the user, sequence of images and level of features.

Abstract: This paper presents the latest improvements on our Spectro system that detects transformed duplicate audio content. We propose a new binary image feature derived from a spectrogram matrix by using a threshold based on the average of the spectral values. We quantize this binary image by applying a tile of fixed size and computing the sum of each small square in the tile. Fingerprints of each binary image encode the positions of the selected tiles. Evaluation on TRECVID 2010 CBCD data shows that this new feature improves significantly the Spectro system for transformations that add irrelevant speech to the audio. Compared to a state-of-the-art audio fingerprinting system, the proposed method reduces the minimal Normalized Detection Cost Rate (min NDCR) by 33%, improves localization accuracy by 28% and results in 40% fewer missed queries.

Automated Response Actions 2015 |
A recurring problem in cybersecurity is the need to automate systems to reduce human effort and error and to be able to react rapidly and accurately to an intrusion or insertion. The articles cited here describe a number of interesting approaches related to the Science of Security hard topics, including resilience and composability.
Ossenbuhl, S.; Steinberger, J.; Baier, H., "Towards Automated Incident Handling: How to Select an Appropriate Response against a Network-Based Attack?," in IT Security Incident Management & IT Forensics (IMF), 2015 Ninth International Conference on, pp. 51-67, 18-20 May 2015. doi: 10.1109/IMF.2015.13
Abstract: The increasing amount of network-based attacks evolved to one of the top concerns responsible for network infrastructure and service outages. In order to counteract these threats, computer networks are monitored to detect malicious traffic and initiate suitable reactions. However, initiating a suitable reaction is a process of selecting an appropriate response related to the identified network-based attack. The process of selecting a response requires to take into account the economics of an reaction e.g., risks and benefits. The literature describes several response selection models, but they are not widely adopted. In addition, these models and their evaluation are often not reproducible due to closed testing data. In this paper, we introduce a new response selection model, called REASSESS, that allows to mitigate network-based attacks by incorporating an intuitive response selection process that evaluates negative and positive impacts associated with each countermeasure. We compare REASSESS with the response selection models of IE-IRS, ADEPTS, CS-IRS, and TVA and show that REASSESS is able to select the most appropriate response to an attack in consideration of the positive and negative impacts and thus reduces the effects caused by an network-based attack. Further, we show that REASSESS is aligned to the NIST incident life cycle. We expect REASSESS to help organizations to select the most appropriate response measure against a detected network-based attack, and hence contribute to mitigate them.

Abstract: This paper describes an automated process of active perception for cyber defense. Our approach is informed by theoretical ideas from decision theory and recent research results in neuroscience. Our cognitive agent allocates computational and sensing resources to (approximately) optimize its Value of Information. To do this, it draws on models to direct sensors towards phenomena of greatest interest to inform decisions about cyber defense actions. By identifying critical network assets, the organization's mission measures interest (and value of information). This model enables the system to follow leads from inexpensive, inaccurate alerts with targeted use of expensive, accurate sensors. This allows the deployment of sensors to build structured interpretations of situations. From these, an organization can meet mission-centered decision-making requirements with calibrated responses proportional to the likelihood of true detection and degree of threat.

Abstract: The Current Methodologies of virtual and Automated Testing on touch screen displays are limited, since, minor screen changes and display software updates will cause the automated tests to fail and hence there will be a need to fix them. Addition of new items to a drop-down list, movement of buttons, reusability and conversion of Test scripts for similar devices will be a cumbersome job. The general approach of testing Display manually, is not feasible due to sluggishness, monotony and repetitiveness of work, which can cause manual errors in different volumes at different times, it will also reduce the option of Batch executions of tests 24???7. The automated approach for testing such Displays through XY coordinates pointing on screen, taking Screen captures and using optical character recognition for verification methods are non-reliable and affects the performance of testing. This makes automating a test difficult, causes a high amount of risk as well as high maintenance costs. This paper offers recent ideas and its implementation of software testing, on touch screen Displays, which are widely used in sophisticated passenger cars as well as in off-highway equipment like tractors, construction and Forestry etc. In this method of testing the Display's User interface, we use ???Test Events??? which are linked with different objects/Icons on displays. Every user action like selecting menu item from dropdown, pressing button, swiping, turning pages are considered as unique actions, and these actions are then bundled with unique Object Id data to create the events on the Display. These user events are simulated automatically and the response is monitored and logged for identifying and analyzing Software defects. The architecture is based on "Data Driven Model" where test data is separated from script in order to take care of any changes in quick and agile way. The Data such as unique references to objects and Pools on the screen are placed in SQL Database, this enables- to access data from different locations by multiple users. Though, the approach can be widely applied to majority of Touch screen applications, we restrict the scope of this paper to automotive domain due to the Standards and protocol used during implementation.

Abstract: Fault tolerant Resource consumption in Desktop grid is a motivational area in research. The present research paper focuses on the dimensions of Fault Tolerant resource usage especially in area of available computational power. Desktop grid resources are accountable for generation of computational power. Alchemi Desktop middleware is useful for collection of computational power on diverse machines in Microsoft window based environment. Failure and Fault in execution side can create serious problem, in addition to a direct impact on computational power in Real Time Environment. In the Environment of faults, control on the available computational power is very necessary in grid middleware. This problem has not been addressed so far. Alchemi Desktop Grid Middleware provides a manual Procedure for control of computational power in Real Time Environment. There is no automated mechanism available for controlling the processing power in alchemi desktop grid. This Research work has proposed, designed & developed automated framework for Alchemi Grid middleware. Framework can take control on available computational power in Real Time Environment at Time of Fault in execution processes. Testing for the framework is done in Real Time environment. Results after test show that framework gives quick response for controlling available computational power. Framework is able to detect defective process machine and correct fault in milliseconds which will cooperative to maintain level of available computational power In Real time Environment. This Research work has tried to eliminate Manual Procedure for controlling computational power by using automated Method for quick action in case of execution side faults.

Abstract: One big challenge raised by frequent topology change in today's power system is assessing the system protection security and dependability afterwards. This paper reviews the setting algorithm for the distance relays and proposes an automated setting calculation module. The calculation procedure is broken down into blocks which could be processed in parallel in order to improve the computation speed. The module could be used to assess the system protection vulnerabilities following a topology change in instances when multiple switching actions are done in response to occurrence of cascading faults or as a result of intentional control action. The module performance is tested on New England 39-bus and IEEE 118-bus systems. A sensitivity analysis in the form of N-2 contingency impact on the network relay settings is conducted on both test systems.

A Dataset of Spontaneous Affective Response of Online Advertising (SARA) for Audience Behavior Analysis," in Automatic Face and Gesture Recognition (FG), 2015 11th IEEE International Conference and Workshops on, vol. 1, pp. 1-8, 4-8 May 2015. doi: 10.1109/FG.2015.7163153
Abstract: In marketing and advertising research, “zapping” is defined as the action when a viewer skips a commercial advertisement. Researchers analyze audience's behavior in order to prevent zapping, which helps advertisers to design effective commercial advertisements. Since emotions can be used to engage consumers, in this paper, we leverage automated facial expression analysis to understand consumers' zapping behavior. To this end, we collect 612 sequences of spontaneous facial expression videos by asking 51 participants to watch 12 advertisements from three different categories, namely Car, Fast Food, and Running Shoe. In addition, the participants also provide self-reported reasons of zapping. We adopt a data-driven approach to formulate a zapping/non-zapping binary classification problem. With an in-depth analysis of expression response, specifically smile, we show a strong correlation between zapping behavior and smile response. We also show that the classification performance of different ad categories correlates with the ad's intention for amusement. The video dataset and self-reports are available upon request for the research community to study and analyze the viewers' behavior from their facial expressions.

Abstract: Automated demand response (ADR) is an essential technology for demand management such as real-time pricing. A major issue for ADR is the design of the units which control electric supply to each electric devise according to the price, so as to benefit both the supplier and consumer sides. Although a kind of universal design principle must be useful for the issue, it has never been established so far. This paper thus attempts to derive a design principle of the ADR units for real-time pricing and proposes ADR units based on it. First, as a design principle, it is clarified that the heterogeneity of the consumer-side actions is essential to control the total electric power consumption. Based on it, we propose randomized ADR units to artificially produce the heterogeneity. In each proposed unit, a random number is generated and electric power is provided to the connected electric devise only if a price-dependent condition is satisfied for the resulting random number. The proposed units enable the consumers to automatically buy electricity with a low price and allow the supplier to control the total consumption. They also guarantee the scalability of the resulting real-time pricing system.

Abstract: Electrically-evoked compound action potentials (ECAPs) is an objective measure of peripheral neural encoding of electrical stimulation delivered by cochlear implants (CIs) at the auditory nerve level. ECAPs play a key role in automated CI fitting and outcome diagnosis, as long as presence of genuine ECAP is accurately detected automatically. Combination of ECAP amplitudes and signal-to-noise ratio are shown to efficiently detect true responses, by comparing them to subjective visual expert judgments. Corresponding optimal thresholds were calculated from Receiver-Operating-Characteristic curves. This was conducted separately on three artifact rejection methods: alternate polarity, masker-probe and modified-masker-probe. This model resulted in sensitivity and specificity error of 3.3% in learning, 3.5% in testing and 5.0% in verification. It was found that the following combination of ECAP amplitude and signal-to-noise ratio would be accurate predictors: 22 μV and 1.3 dB SNR thresholds for alternate polarity, 35 μV and -0.2 dB for masker-probe and 44 μV and -0.2 dB for modified-masker-probe.

Abstract: Disaster response actors and decision makers need to perform several tasks and decisions in a short time. Handling such tasks requires access to sufficient, relevant and up-to-date datasets. Some of these datasets are static such as road network infrastructure and map of buildings. While several other kind of required information are dynamic and change during the occurrence of disaster. Such information may include number of casualties, wind speed, wind direction, road obstacles, etc. Semantic integration of various sources of information is the key to making efficient and fast actions by the actors in the filed as well as top-level decision makers. In this paper, we elaborate on the research challenges of data integration from multiple heterogeneous sources by proposing the system architecture of ASSIST (Access, Semantic Search and Integration Service and Translation). The paper concludes with discussing the future work on this smart service.

Abstract: In this paper, we present a process, developed over years of practical commercial use, where applications accomplishing a wide variety of complex tasks are created from a common framework, through the use, recombination and iterative refinement of autonomous agents in a Multi-Agent Intelligent System. Driven by a need to solve real-world problems, our focus is to make businesses run more efficiently in an increasingly complex world of systems and software that must work together seamlessly. By listening closely to our customers' problems, we discovered points of commonality, as well as patterns of anomalies related to the flow of data through communication channels and data processing systems, include accounting, inventory, customer relationship management, scheduling systems and many more. We solved their problems through the creation of an Intelligent System, where we defined and implemented software agents that were highly configurable, responsive in real-time and useable in various settings. Autonomous agents adhere to a standard format of three major components: the goal or triggering criteria, the action, and the adaptation response. Agents run within a common Intelligent System framework and agent libraries provide a vast set of component behaviors to build applications from. Agents have one or more of the following component behaviors: sensory aware, geo-position aware, temporally aware, API aware, device aware, and many more. Additionally, there are manager-level agents whose goal is to keep the overall system in balance, through dynamic resource allocation on a system level. To prove the viability of this process, we present a variety of applications representing wide ranging behaviors, many with overlapping agents, created via this approach, all of which are in active commercial use. Finally, we discuss future enhancements toward self-organization, where end users express their requirements declaratively to solve larger business needs, resulting in the automatic instantiation of a solution specific intelligent system.

Abstract: About some years ago, several biometric technologies are considered mature enough to be a new tool for security and ear-based person identification is one of these technologies. This technology provides a reliable, low cost and user-friendly viable solution for a range of access control applications. In this paper, we propose an efficient online personal identification system based on ear images. In this purpose, the identification algorithm aims to extract, for each ear, a specific set of features. Based on Gabor filter response, three ear features have been used in order to extract different and complementary information: phase, module and a combination of the real and imaginary parts. Using these features, several combinations are tested in the fusion phase in order to achieve an optimal multi-representation system which leads to a better identification accuracy. The obtained experimental results show that the system yields the best performance for identifying a person and it is able to provide the highest degree of biometrics-based system security.

Abstract: This paper presents a system that provides mitigation for DDoS attacks as a service, and is capable of handling flash crowd events at the same time. Providing DDoS protection as a service represents an important solution especially for Websites that have limited resources with no infrastructure in place for defense against these attacks. The proposed system is composed of two main components: (i) The distributed CAPTCHA service, which comprises a large number of powerful nodes geographically and suitably distributed in the Internet acting as a large distributed firewall, and (ii) The HTTP redirect module, which is a stateless HTTP server that redirects Web requests destined to the targeted Webserver to one of the CAPTCHA nodes. The CAPTCHA node can then segregate legitimate clients from automated attacks by requiring them to solve a challenge. Upon successful response, legitimate clients (humans) are forwarded through a given CAPTCHA node to the Webserver.

Balfour, R.E., "Building The “Internet of Everything” (IoE) for First Responders," in Systems, Applications and Technology Conference (LISAT), 2015 IEEE Long Island, pp. 1-6, 1-1 May 2015. doi: 10.1109/LISAT.2015.7160172
Abstract: The “Internet of Everything” (IoE) describes the “bringing together of people, process, data, and things to make networked connections more relevant and valuable than ever before”. IoE encompasses both machine-to-machine (M2M) and Internet-of-Things (IoT) technologies, and it is the pervasiveness of IoE than can be leveraged to achieve many things for many people, including first responders. The emerging IoE will continue to evolve over the next ten years and beyond, but the IoT can happen now, with automated M2M communications bringing first responder communications and situational awareness to the leading-edge of IoE-leveraged technology - exactly where they belong as they risk their lives to protect and save others. Presented here are a number of technological capabilities that are critical to achieving the IoE, especially for first responders and emergency managers, including (a) Security; (b) a global M2M standard; (c) powerful four-dimensional M2M applications; and (d) Data Privacy and trust. For advanced security, Software Defined network Perimeters (SDP) can provide the critical functionality to protect and secure M2M nodes in an ad-hoc M2M IoT/IoE network. Without a secure, dynamic, M2M network, the vision of an emergency responder instantly communicating with a “smart building” would not be feasible. But with SDP, it can, and will, happen. SDP enables an ad-hoc, secure M2M network to rapidly deploy and “hide in plain sight”. In an emergency response situation, this is exactly what we need. For M2M/IoT to go mobile and leverage global IoE capabilities anywhere (which is what emergency responders need as emergency locations are somewhat unpredictable and change every day), a global industry standard must be, and is being, developed: oneM2M. And the existing fourDscape® technology/platform could quickly support a oneM2M system structure that can be deployed in the short term, with the fo- rDscape browser providing powerful M2M IoT/IoE applications and 4D visualizations. Privacy-by-design principles can also be applied and other critical related issues addressed beyond privacy (i.e. once privacy is achieved and available IoE sensors/data can be leveraged), such as trusting, scaling, hacking, and securing M2M IoT/IoE devices and systems. Without the full package of IoE innovation embracing the very public IoE world in a very private and secure way, and can continue to evolve in parallel with emerging commercial IoE technology, first responders would not be able to leverage the commercial state-of-the-art in the short term and in the years to come. Current technology innovation can change that.

Abstract: A digital forensics investigation may involve procedures for both live forensics and for gathering evidence from a device in a forensics laboratory. Due to the focus on capturing volatile data during a live forensics investigation, tools have been developed that are aimed at capturing specific data surrounding state information. However, there may be circumstances whereby non-volatile data analysis, such as the identification of files of interest, is also required. In such an investigation, the ability to use file-wise, or hash, signatures is precluded due to pre-processing requirements by the forensics tools. Therefore, this paper presents SlackStick, a novel automated approach run from a USB memory device for the identification of files of interest or non-volatile evidence triage using an alternative signature scheme. Moreover, the approach may be used by inexpert users during a first-response phase of an investigation. The results of the case study presented in this paper demonstrate the applicability of the approach.

Abstract: The smart grid changes the way energy is produced and distributed. In addition both, energy and information is exchanged bidirectionally among participating parties. Therefore heterogeneous systems have to cooperate effectively in order to achieve a common high-level use case, such as smart metering for billing or demand response for load curtailment. Furthermore, a substantial amount of personal data is often needed for achieving that goal. Capturing and processing personal data in the smart grid increases customer concerns about privacy and in addition, certain statutory and operational requirements regarding privacy aware data processing and storage have to be met. An increase of privacy constraints, however, often limits the operational capabilities of the system. In this paper, we present an approach that automates the process of finding an optimal balance between privacy requirements and operational requirements in a smart grid use case and application scenario. This is achieved by formally describing use cases in an abstract model and by finding an algorithm that determines the optimum balance by forward mapping privacy and operational impacts. For this optimal balancing algorithm both, a numeric approximation and - if feasible - an analytic assessment are presented and investigated. The system is evaluated by applying the tool to a real-world use case from the University of Southern California (USC) microgrid.

Abstract: Phishing is a widespread practice and a lucrative business. It is invasive and hard to stop: a company needs to worry about all emails that all employees receive, while an attacker only needs to have a response from a key person, e.g., a finance or human resources' responsible, to cause a lot of damages. Some research has looked into what elements make phishing so successful. Many of these elements recall strategies that have been studied as principles of persuasion, scams and social engineering. This paper identifies, from the literature, the elements which reflect the effectiveness of phishing, and manually quantifies them within a phishing email sample. Most elements recognised as more effective in phishing commonly use persuasion principles such as authority and distraction. This insight could lead to better automate the identification of phishing emails and devise more appropriate countermeasures against them.

Abstract: Deception is pervasive, often leading to adverse consequences for individuals, organizations, and society. Information systems researchers are developing tools and evaluating sensors that can be used to augment human deception judgments. One sensor exhibiting particular promise is the eye tracker. Prior work evaluating eye trackers for deception detection has focused on the detection and interpretation of brief eye behavior variations in response to stimuli (e.g, images) or interview questions. However, research is needed to understand how eye behaviors evolve over the course of an interaction with a deception detection system. Using latent growth curve modeling, we test how pupil diameter evolves over one's interaction with a deception detection system. The results indicate that pupil diameter changes over the course of a deception detection interaction, and that these trends are indicative of deception during the interaction, regardless if incriminating target items are shown.

Compiler Security 2015 |
Much of software security focuses on applications, but compiler security should also be an area of concern. Compilers can “correct” secure coding in the name of efficient processing. The works cited here look at various approaches and issues in compiler security. These works were presented in 2015.
D'Silva, V.; Payer, M.; Song, D., "The Correctness-Security Gap in Compiler Optimization," in Security and Privacy Workshops (SPW), 2015 IEEE, pp.73-87, 21-22 May 2015. doi: 10.1109/SPW.2015.33
Abstract: There is a significant body of work devoted to testing, verifying, and certifying the correctness of optimizing compilers. The focus of such work is to determine if source code and optimized code have the same functional semantics. In this paper, we introduce the correctness-security gap, which arises when a compiler optimization preserves the functionality of but violates a security guarantee made by source code. We show with concrete code examples that several standard optimizations, which have been formally proved correct, in-habit this correctness-security gap. We analyze this gap and conclude that it arises due to techniques that model the state of the program but not the state of the underlying machine. We propose a broad research programme whose goal is to identify, understand, and mitigate the impact of security errors introduced by compiler optimizations. Our proposal includes research in testing, program analysis, theorem proving, and the development of new, accurate machine models for reasoning about the impact of compiler optimizations on security.

Abstract: A prominent threat to embedded systems security is represented by side-channel attacks: they have proven effective in breaching confidentiality, violating trust guarantees and IP protection schemes. State-of-the-art countermeasures reduce the leaked information to prevent the attacker from retrieving the secret key of the cipher. We propose an alternate defense strategy augmenting the regular information leakage with false targets, quite like chaff countermeasures against radars, hiding the correct secret key among a volley of chaff targets. This in turn feeds the attacker with a large amount of invalid keys, which can be used to trigger an alarm whenever the attack attempts a content forgery using them, thus providing a reactive security measure. We realized a LLVM compiler pass able to automatically apply the proposed countermeasure to software implementations of block ciphers. We provide effectiveness and efficiency results on an AES implementation running on an ARM Cortex-M4 showing performance overheads comparable with state-of-the-art countermeasures.

Abstract: Computer virus is a rapidly evolving threat to the computing community. These viruses fall into different categories. It is generally believed that metamorphic viruses are extremely difficult to detect. Metamorphic virus generating kits are readily available using which potentially dangerous viruses can be created with very little knowledge or skill. Classification of computer virus is very important for effective defection of any malware using anti virus software. It is also necessary for building and applying right software patch to overcome the security vulnerability. Recent research work on Hidden Markov Model (HMM) analysis has shown that it is more effective tool than other techniques like machine learning in detecting of computer viruses and their classification. In this paper, we present a classification technique based on Hidden Markov Model for computer virus classification. We trained multiple HMMs with 500 malware files belonging to different virus families as well as compilers. Once trained the model was used to classify new malware of its kind efficiently.

Abstract: Software-Defined Networking (SDN) is a different approach to manage a network by software. It could use well-defined software expressions and predicates to regulate network behavior. Current SDN controllers, such as Floodlight, offer a framework to develop, test and run applications that control the network operation, including the firewall function. However, they are not able to validate firewall policies, detect conflicts; neither avoids contradictory configurations on network devices. Some compilers only detect conflicts by a subset of the language; hence, it cannot detect conflicts related to contradicting rules with security controls. This paper presents our framework based on Alloy called FireWell. FireWell is able to model firewall policies as formal predicates to validate, detect and prevent conflicts in firewall policies. In addition we present the implementation of FireWell and test it using the Floodlight controller and firewall application.

Abstract: Static analysis is a widely adopted technique in the industrial development of software systems. It allows to automatically check for code compliance with respect to predefined programming rules. When applied to large software systems, sanitizing the code in an efficient way requires a careful guidance, as a high number of (more or less relevant) rule infringements can result from the analysis. We report the results of a static analysis study conducted on several industrial software systems developed by SELEX ES, a large manufacturer of software-intensive mission-critical systems. We analyzed results on a set of 156 software components developed in SELEX ES, based on them, we developed and experimented an approach to prioritize components and violated rules to correct for a cost-effective code sanitization. Results highlight the benefits that can be achieved in terms of quality targets and incurred cost.

Abstract: Due to the search for improving vehicle safety, security and reliability, the challenges in the automotive sector have continued to increase in order to confront these requirements. In this context, we have implemented a vehicle Simulink blockset model. The proposed blockset corresponds to the Society of Automotive Engineers SAE benchmark model which is normally connected by the CAN bus we extended it to the FlexRay Bus. We have chosen the Embedded Matlab tool for implementing this blockset. It permits us to generate C code for different blocks in order to validate the vehicle system design.

Abstract: Compute-intensive applications incorporate ever increasing data processing requirements on hardware systems. Many of these applications have only recently become feasible thanks to the increasing computing power of modern processors. The Matlab language is uniquely situated to support the description of these compute-intensive scientific applications, and consequently has been continuously improved to provide increasing computational support in the form of multithreading for CPUs and utilizing accelerators such as GPUs and FPGAs. Moreover, to take advantage of the computational support in these heterogeneous systems from the problem domain to the computer architecture necessitates a wide breadth of knowledge and understanding. In this work, we present a framework for the development of compute-intensive scientific applications in Matlab using heterogeneous processor systems. We investigate systems containing CPUs, GPUs, and FPGAs. We leverage the capabilities of Matlab and supplement them by automating the mapping, scheduling, and parallel code generation. Our experimental results on a set of benchmarks achieved from 20x to 60x speedups compared to the standard Matlab CPU environment with minimal effort required on the part of the user.

Abstract: Hardware errors are becoming more prominent with reducing feature sizes, however tolerating them exclusively in hardware is expensive. Researchers have explored software-based techniques for building error resilient applications for hardware faults. However, software based error resilience techniques need configurable and accurate fault injection techniques to evaluate their effectiveness. In this paper, we present LLFI, a fault injector that works at the LLVM compiler's intermediate representation (IR) level of the application. LLFI is highly configurable, and can be used to inject faults into selected targets in the program in a fine-grained manner. We demonstrate the utility of LLFI by using it to perform fault injection experiments into nine programs, and study the effect of different injection choices on their resilience, namely instruction type, register target and number of bits flipped. We find that these parameters have a marked effect on the evaluation of overall resilience.

Abstract: Information leakage via timing side-channel attacks is one of the main threats that target code executing on remote platforms such as the cloud computing environment. These attacks can be further leveraged to reverse-engineer or even tamper with the running code. In this paper, we propose a security obfuscation technique, which helps making the generated code more resistant to these attacks, by means of increasing logical complexity to hinder the formulation of a solid hypothesis about code behavior. More importantly, this software solution is portable, generic and does not require special setup or hardware or software modifications. In particular, we consider mangling the control-flow inside a program via converting a random set of conditional branches into linear code, using if conversion transformation. Moreover, our method exploits the dynamic compilation technology to continually and randomly alter the branches. All of this mangling should diversify code execution, hence it becomes difficult for an attacker to infer timing correlations through statistical analysis. We extend the LLVM JIT compiler to provide for an initial investigation of this approach. This makes our system applicable to a wide variety of programming languages and hardware platforms. We have studied the system using a simple test program and selected benchmarks from the standard SPEC CPU 2006 suite with different input loads and experimental setups. Initial results show significant changes in program's control-flow and hence data dependences, resulting in noticeable different execution times even for the same input data, thereby complicating such attacks. More notably, the performance penalty is within reasonable margins.

Abstract: Side-channel attacks are currently among the most serious threats for embedded systems. Popular countermeasures to mitigate the impact of such attacks are masking schemes, where secret intermediate values are split in two or more values by virtue of secret sharing. Processing the secret happens on separate execution paths, which are executed on the same central processing unit (CPU). In case of unwanted correlations between different registers inside the CPU the shared secret may leak out through a side-channel. This problem is particularly evident on low cost embedded systems, such as nodes for the Internet of Things (IoT), where cryptographic algorithms are often implemented in pure software on a reduced instruction set computer (RISC). On such an architecture, all data manipulation operations are carried out on the contents of the CPU's register file. This means that all intermediate values of the cryptographic algorithm at some stage pass through the register file. Towards avoiding unwanted correlations and leakages thereof, special care has to be taken in the mapping of the registers to intermediate values of the algorithm. In this work, we describe an empirical study that reveals effects of unintended unmasking of masked intermediate values and thus leaking secret values. The observed phenomena are related to the leakage of masked hardware implementations caused by glitches in the combinatorial path of the circuit but the effects are abstracted to the level of the instruction set architecture on a RISC CPU. Furthermore, we discuss countermeasures to have the compiler thwart such leakages.

Abstract: Identifying equivalent mutants remains the largest impediment to the widespread uptake of mutation testing. Despite being researched for more than three decades, the problem remains. We propose Trivial Compiler Equivalence (TCE) a technique that exploits the use of readily available compiler technology to address this long-standing challenge. TCE is directly applicable to real-world programs and can imbue existing tools with the ability to detect equivalent mutants and a special form of useless mutants called duplicated mutants. We present a thorough empirical study using 6 large open source programs, several orders of magnitude larger than those used in previous work, and 18 benchmark programs with hand-analysis equivalent mutants. Our results reveal that, on large real-world programs, TCE can discard more than 7% and 21% of all the mutants as being equivalent and duplicated mutants respectively. A human-based equivalence verification reveals that TCE has the ability to detect approximately 30% of all the existing equivalent mutants.

Abstract: In this paper, we present an analysis of HTTP traffic in a large-scale environment which uses network flow monitoring extended by parsing HTTP requests. In contrast to previously published analyses, we were the first to classify patterns of HTTP traffic which are relevant to network security. We described three classes of HTTP traffic which contain brute-force password attacks, connections to proxies, HTTP scanners, and web crawlers. Using the classification, we were able to detect up to 16 previously undetectable brute-force password attacks and 19 HTTP scans per day in our campus network. The activity of proxy servers and web crawlers was also observed. Symptoms of these attacks may be detected by other methods based on traditional flow monitoring, but detection using the analysis of HTTP requests is more straightforward. We, thus, confirm the added value of extended flow monitoring in comparison to the traditional method.

Abstract: Use-after-free conditions occur when an execution path of a process accesses an incorrectly deal located object. Such access is problematic because it may potentially allow for the execution of arbitrary code by an adversary. However, while increasingly common, such flaws are rarely detected by compilers in even the most obvious instances. In this paper, we design and implement a static analysis method for the detection of use-after-free conditions in binary code. Our new analysis is similar to available expression analysis and traverses all code paths to ensure that every object is defined before each use. Failure to achieve this property indicates that an object is improperly freed and potentially vulnerable to compromise. After discussing the details of our algorithm, we implement a tool and run it against a set of enterprise-grade, publicly available binaries. We show that our tool can not only catch textbook and recently released in-situ examples of this flaw, but that it has also identified 127 additional use-after-free conditions in a search of 652 compiled binaries in the Windows system32 directory. In so doing, we demonstrate not only the power of this approach in combating this increasingly common vulnerability, but also the ability to identify such problems in software for which the source code is not necessarily publicly available.

Abstract: Nowadays, security breaches are greatly increasing in number. This is one of the major threats that are being faced by most organisations which usually lead to a massive loss. The major cause for these breaches could potentially be the vulnerabilities in software products. There are many tools available to detect such vulnerabilities but detection and correction of vulnerabilities during development phase would be more beneficial. Though there are many standard secure coding practices to be followed in development phase, software developers fail to utilize them and this leads to an unsecured end product. The difficulty in manual analysis of vulnerabilities in source code is what leads to the evolution of automated analysis tools. Static and dynamic analyses are the two complementary methods used to detect vulnerabilities in development phase. Static analysis scans the source code which eliminates the need of execution of the code but it has many false positives and false negatives. On the other hand, dynamic analysis tests the code by running it along with the test cases. The proposed approach integrates static and dynamic analysis. This eliminates the false positives and false negatives problem of the existing practices and helps developers to correct their code in the most efficient way. It deals with common buffer overflow vulnerabilities and vulnerabilities from Common Weakness Enumeration (CWE). The whole scenario is implemented as a web interface.

Abstract: Memory corruption attacks that exploit software vulnerabilities have become a serious problem on the Internet. Effective protection and/or mitigation technologies aimed at countering these attacks are currently being provided with operating systems, compilers, and libraries. Unfortunately, the attacks continue. One of the reasons for this state of affairs can be attributed to the uneven diffusion of the latest (and thus most potent) protection and/or mitigation technologies. This results because attackers are likely to have found ways of circumventing most well-known older versions, thus causing them to lose effectiveness. Therefore, in this paper, we will explore diffusion of relatively new technologies, and analyze the results of a Linux distributions survey.

Abstract: Code-reuse attacks such as return-oriented programming (ROP) pose a severe threat to modern software. Designing practical and effective defenses against code-reuse attacks is highly challenging. One line of defense builds upon fine-grained code diversification to prevent the adversary from constructing a reliable code-reuse attack. However, all solutions proposed so far are either vulnerable to memory disclosure or are impractical for deployment on commodity systems. In this paper, we address the deficiencies of existing solutions and present the first practical, fine-grained code randomization defense, called Read actor, resilient to both static and dynamic ROP attacks. We distinguish between direct memory disclosure, where the attacker reads code pages, and indirect memory disclosure, where attackers use code pointers on data pages to infer the code layout without reading code pages. Unlike previous work, Read actor resists both types of memory disclosure. Moreover, our technique protects both statically and dynamically generated code. We use a new compiler-based code generation paradigm that uses hardware features provided by modern CPUs to enable execute-only memory and hide code pointers from leakage to the adversary. Finally, our extensive evaluation shows that our approach is practical -- we protect the entire Google Chromium browser and its V8 JIT compiler -- and efficient with an average SPEC CPU2006 performance overhead of only 6.4%.

Abstract: Recently, Jump-oriented Programming (JOP) attack has become widespread in various systems including server, desktop, and smart devices. JOP attack rearranges existing code snippets in program to make gadget sequences, and hijacks control flow of program by chaining and executing gadget sequences consecutively. However, existing defense schemes have limitations such as high execution overhead, high binary size increase overhead, and low applicability. In this paper, to solve these problems, we introduce target shepherding, which is a fast and space-efficient defender against general JOP attack. Our defense scheme generates monitoring code to determine whether the target is legitimate or not just before each indirect jump instruction at compile time, and then checks whether a control flow has been subverted by JOP attack at run time. We achieved very low run-time overhead with very small increase in file size. In our experimental results, the performance overhead is 2.36% and the file size overhead is 5.82% with secure execution.

Abstract: The common means of defense for network security systems is to block the intrusions by matching the signatures. Intrusion-signature matching is the critical operation. However, small and medium-sized enterprise (SME) or Small Office Home Office (SOHO) network security systems may not have sufficient resources to maintain good matching performance with full-set rules. Code generation is a technique used to convert data structures or instruction to other forms to obtain greater benefits within execution environments. This study analyzes intrusion detection system (IDS) signatures and discovers character occurrence to be significantly uneven. Based on this property, this study designs a method to generate a string matching source code according to the state table of AC algorithm for embedded network intrusion detection platforms. The generated source code requires less memory and relies not only on table lookup, but also on the ability of processor. This method can upgrade the performance by compiling optimization and contribute to the application of network processors and DSP-like based platforms. From evaluation, this method requires use of only 20% memory and can achieve 86% performance in clean traffic compared to the original Aho-Corasick algorithm (AC).

Abstract: Cloud computing sparked interest in Verifiable Computation protocols, which allow a weak client to securely outsource computations to remote parties. Recent work has dramatically reduced the client's cost to verify the correctness of their results, but the overhead to produce proofs remains largely impractical. Geppetto introduces complementary techniques for reducing prover overhead and increasing prover flexibility. With Multi QAPs, Geppetto reduces the cost of sharing state between computations (e.g, For MapReduce) or within a single computation by up to two orders of magnitude. Via a careful choice of cryptographic primitives, Geppetto's instantiation of bounded proof bootstrapping improves on prior bootstrapped systems by up to five orders of magnitude, albeit at some cost in universality. Geppetto also efficiently verifies the correct execution of proprietary (i.e, Secret) algorithms. Finally, Geppetto's use of energy-saving circuits brings the prover's costs more in line with the program's actual (rather than worst-case) execution time. Geppetto is implemented in a full-fledged, scalable compiler and runtime that consume LLVM code generated from a variety of source C programs and cryptographic libraries.

Cross Layer Security 2015 |
Protocol architectures traditionally followed strict layering principles to ensure interoperability, rapid deployment, and efficient implementation. But a lack of coordination between layers limits the performance of these architectures. More important, the lack of coordination may introduce security vulnerabilities and potential threat vectors. The literature cited here addresses the problems and opportunities available for cross layer security published in 2015.

Abstract: In This Paper, we report a new approach for providing security as well as privacy to the corporate user. With the help of locations sensing mechanism by using GPS we can avoid the un-authorized reading & relay attacks on RFID system. For example, location sensing mechanism with RFID card is used for location specific application such as ATM cash transfer van for open the door of van. So after reaching the pre-specified location (ATM) the RFID card is active & then it accepts the fingerprint of the registered person only. In this way we get a stronger cross layer security. SHA-3 algorithm is used to avoid the collision (due to fraud fingerprint) effect on server side.

Abstract: Routing protocols in Wireless Sensor Network (WSN) are responsible for propagating and coordinating of information transfer from one end of the network to the other. Dynamic Window Secured Implicit Geographic Forwarding (DWSIGF) is a robust, cross layer, security bound routing protocol that propagates information in a multi-hop network using the greedy and random forwarding strategies. These strategies are known for their poor resistivity to interference and erratic behavior in path selection. In this paper, we propose a forwarding strategy that uses an optimal distance to mitigate these problems. The optimal distance is computed based on the path loss coefficient and energy dissipated in the hardware (sensor). Extensive simulations have been conducted to evaluate the performance of the proposed approach. The results illustrate that the proposed approach performs better than the compared strategies in terms of packet delivery ratio and energy consumption.

Abstract: In most Wireless Sensor Network (WSN) applications the sensors forward their readings to a central sink or base station (BS). The unique role of the BS makes it a natural target for an adversary's attack. Even if a WSN employs conventional security mechanisms such as encryption and authentication, an adversary may apply traffic analysis techniques to locate the BS. This motivates a significant need for improved BS anonymity to protect the identity, role, and location of the BS. Published anonymity-boosting techniques mainly focus on a single layer of the communication protocol stack and assume that changes in the protocol operation will not be detectable. In fact, existing single-layer techniques may not be able to protect the network if the adversary could guess what anonymity measure is being applied by identifying which layer is being exploited. In this paper we propose combining physical-layer and network-layer techniques to boost the network resilience to anonymity attacks. Our cross-layer approach avoids the shortcomings of the individual single-layer schemes and allows a WSN to effectively mask its behavior and simultaneously misdirect the adversary's attention away from the BS's location. We confirm the effectiveness of our cross-layer anti-traffic analysis measure using simulation.

Abstract: Secure yet lightweight protocol for communication over the Internet is a pertinent problem for constrained environments in the context of Internet of Things (IoT) / Machine to Machine (M2M) applications. This paper extends the initial approaches published in [1], [2] and presents a novel cross-layer lightweight implementation to establish a secure channel. It distributes the responsibility of communication over secure channel in between the application and transport layers. Secure session establishment is performed using a payload embedded challenge response scheme over the Constrained Application Protocol (CoAP) [3]. Record encryption mechanism of Datagram Transport Layer Security (DTLS) [4] with Pre-Shared Key (PSK) [5] is used for encrypted exchange of application layer data. The secure session credentials derived from the application layer is used for encrypted exchange over the transport layer. The solution is designed in such a way that it can easily be integrated with an existing system deploying CoAP over DTLS-PSK. The proposed method is robust under different security attacks like replay attack, DoS and chosen cipher text. The improved performance of the proposed solution is established with comparative results and analysis.

Abstract: This paper considers potential risks to data security in multi-hop infrastructureless wireless networks where cross-layer routing protocols are used. We show that an adversary, as long as it controls a few of the nodes, and with the help of a few assisting jammers, can extend control over a significant portion of the data in the network even with very simple strategies and limited resources, by creating a so-called “wormhole” even without off-band links. We refer to this jamming-assisted data control threat as hammer and anvil attack. We model a prototype of the hammer and anvil attack in a wireless sensor network scenario with distributed cross-layer routing protocols. We show through extensive performance evaluation that the attack poses a serious threat to the resulting data security, and we provide observations that can be helpful in fine-tuning the attack, as well as in designing defense mechanisms against it.

Abstract: Rendezvous in cognitive radio networks (CRNs) facilitates cognitive radio (CR) users to find common channels and establish a communication link. Due to the dynamic radio environment, rendezvous on a predetermined common control channel (CCC) is limited by a single point of failure, congestion and security. Channel hopping (CH) provides an efficient solution to achieve rendezvous in cognitive radio ad-hoc networks (CRAHNs). In this paper, a cross layer CH rendezvous protocol is proposed which use the channel preference of a CR user to establish a communication link. The channel preference of a CR user is determined by channel ranking based on PUs and CRs activities which is physical layer parameter. We formulate the channel ranking as a linear optimization problem based on the channel availability under collision constraints. Thereby, abreast of channel quantity, we integrate the channel quality to design a CH rendezvous protocol. Simulation results show that the proposed Channel ranking based channel hopping (CRCH) scheme outperforms with similar CH schemes in terms of average time-to-rendezvous (ATTR) and the degree of overlap in asymmetric channel scenario.

Abstract: In this paper, we introduce a cross-layer, application-oriented communication protocol for Wireless Sensor Networks (WSN). TSTP - Trustful Space-Time Protocol - integrates most services recurrently needed by WSN applications: Medium Access Control (MAC), spatial localization, geographic routing, time synchronization and security, and is tailored for geographical monitoring applications. By integrating shared data from multiple services into a single network layer, TSTP is able to eliminate replication of information across services, and achieve a very small overhead in terms of control messages. For instance, spatial localization data is shared by the MAC and routing scheme, the location estimator, and the application itself. Application-orientation allows synergistic co-operation of services and allows TSTP to deliver functionality efficiently while eliminating the need for additional, heterogeneous software layers that usually come with an integration cost.

Abstract: This paper considers simultaneous wireless information and power transfer (SWIPT) in multiple-input single-output (MISO) interference systems in presence of energy harvesting nodes. We investigate the interference temperature minimization problem while satisfying signal-to-interference-and-noise ratio (SINR) and energy harvesting thresholds at the information and energy receivers, respectively. The objective is to improve the received SINR as well as to reduce cross-link information leakage in order to improve physical-layer security. The formulation leads to a non-convex problem which we solve using semidefinite relaxation (SDR) technique. A rank-constrained optimization algorithm is proposed and a rank reduction procedure is developed in order to achieve a lower rank solution. Interestingly, we show that the SDR is in fact tight and an optimal rank-one solution can be developed in certain scenarios. Numerical simulations are performed to demonstrate the effectiveness of the proposed algorithm.

Abstract: Future military operations require versatile and integrated mechanisms for enforcement of the security policies in all three domains of information protection: confidentiality, integrity and availability. We discuss challenges and use cases related to enforcement of integrity and availability policies in federated mission environments and we demonstrate how the concept of Content-based Protection and Release (CPR) can be extended to support such policies. Furthermore, we present an approach to cross-layer enforcement of the CPR policies and introduce a proof-of-concept implementation of the CPR enforcement mechanisms in a software-defined networking environment.

Abstract: Self-awareness has a long history in biology, psychology, medicine, and more recently in engineering and computing, where self-aware features are used to enable adaptivity to improve a system's functional value, performance and robustness. With complex many-core Systems-on-Chip (SoCs) facing the conflicting requirements of performance, resiliency, energy, heat, cost, security, etc. - in the face of highly dynamic operational behaviors coupled with process, environment, and workload variabilities - there is an emerging need for self-awareness in these complex SoCs. Unlike traditional MultiProcessor Systems-on-Chip (MPSoCs), self-aware SoCs must deploy an intelligent co-design of the control, communication, and computing infrastructure that interacts with the physical environment in real-time in order to modify the system's behavior so as to adaptively achieve desired objectives and Quality-of-Service (QoS). Self-aware SoCs require a combination of ubiquitous sensing and actuation, health-monitoring, and statistical model-building to enable the SoC's adaptation over time and space. After defining the notion of self-awareness in computing, this paper presents the Cyber-Physical System-on-Chip (CPSoC) concept as an exemplar of a self-aware SoC that intrinsically couples on-chip and cross-layer sensing and actuation using a sensor-actuator rich fabric to enable self-awareness.

Abstract: Improved network security is addressed using device dependent physical-layer (PHY) based fingerprints from Ethernet cards to augment traditional MAC-based ID verification. The investigation uses unintentional Ethernet cable emissions and device fingerprints comprised of Constellation-Based, Distinct Native Attribute (CB-DNA) features. Near-field collection probe derivative effects dictated the need for developing a two-dimensional (2D) binary constellation for demodulation and CB-DNA extraction. Results show that the 2D constellation provides reliable demodulation (bit estimation) and device discrimination using symbol cluster statistics for CB-DNA. Bit Error Rate (BER) and Cross-Manufacturer Discrimination (CMD) results are provided for 16 devices from 4 different manufactures. Device discrimination is assessed using both Nearest Neighbor (NN) and Multiple Discriminant Analysis, Maximum Likelihood (MDA/ML) classifiers. Overall results are promising and include CMD average classification accuracy of %C = 76.73% (NN) and %C = 91.38% (MDA/ML).

Abstract: To ensure reliable communication in the next-generation space networks, a novel network management system is needed to support greater levels of autonomy and possess greater awareness of the environment and knowledge of assets. Toward this, we developed a security-enhanced autonomous network management approach for the space networks through network monitoring, network analysis, cross-layer negotiation, and network adaptation. In our approach, bundle-based delay/disruption-tolerant networking (DTN) is used as the underlying networking technology. Our approach allows the system to adaptively reconfigure its network elements based upon awareness of network conditions, policies, and mission requirements. Although SEANM is generically applicable to any radio network, for validation it has been prototyped and evaluated on two specific networks - a commercial off-the-shelf hardware testbed using IEEE 802.11 WiFi devices, and a military radio testbed using JTRS AN/PRC-154 Rifleman Radio platforms. Through tests, it has been shown that our solution provides autonomous network management resulting in reliable communications in the delay/disruptive prone environments.

Abstract: Vehicular ad hoc networks (VANETs) based on Car2X communication technologies are about to enter mass production in the next years. Thereby, bandwidth efficiency is a core point of concern due to sharing of a single control channel among many participating stations with high mobility. Up to now, neighborhood aware content dissemination has only been considered for VANET security mechanisms, but not for other protocol layers. Thus, we show that extending on demand distribution of fixed or slowly changing data sets to all layers can reduce delay until full cooperative awareness about cooperating stations is achieved. Moreover, the developed strategy is able to reduce average bandwidth requirements. Thereby, the management entity foreseen in currently standardized VANET frameworks is used to coordinate content dissemination between different protocol layers. A simulation based evaluation is provided, which shows good performance of the proposed mechanism within the current ETSI ITS framework.

Therefore, in this paper, we attempt to develop a mathematical model for throughput of MANETs considering both of the aspects. In addition, we also focus on developing mathematical models for delivery ratio and drop ratio, these metrics limit the maximum throughput of a network. In our analysis, we perform rigorous simulation utilizing ns-2 to capture the performance of MANETs under diversified settings. Our rigorous empirical study reveals that we need to develop cross-layer mathematical models for throughput, delivery ratio, and drop ratio to represent the performance of MANETs and such mathematical models need to resolve higher-order polynomial equations. Consequently, our study uncovers a key finding that mathematical modeling of MANETs considering variation in all parameters is not feasible.

Abstract: Since the start of the 21st century, computer networks have been through an exponential growth in terms of the network capacity, the number of the users and the type of tasks that are performed over the network. With the resent boom of mobile devices (e.g., Tablet computers, smart phones, smart devices, and wearable computing), the number of network users is bound to increase exponentially. But, most of the communications protocols, that span over the 7 layers of the OSI model, were designed in the late 1980's or 90's. Although most of these protocols have had subsequent updates over time, most of these protocols still remain largely unsecure and open to attacks. Hence it is critically important to secure these protocols across the 7 layers of the OSI model. As a part of my PhD research, I am working on a cross layer anomaly behavior detection system for various protocols. This system will be comprised of intrusion detection systems (IDS) for each of the protocols that are present in each layer. The behavior analysis of each protocol will be carried out in two phases. In the first phase (training), the features that accurately characterize the normal operations of the protocol are identified using data mining and statistical techniques and then use them to build a runtime model of protocol normal operations. In addition, some known attacks against the studied protocol are also studied to develop a partial attack model for the protocol. The anomaly behavior analysis modules of each layer are then fused to generate a highly accurate detection system with low false alarms. In the second phase, the cross-layer anomaly based IDS is used to detect attacks against any communication protocols. We have already developed anomaly behavior modules for TCP, UDP, IP, DNS and Wi-Fi protocols. Our experimental results show that our approach can detect attacks accurately and with very low false alarms.

Abstract: Underwater sensor networks (USNs) has many characteristics different from terrestrial wireless sensor networks (WSNs), such as dynamic network topology, unreliable acoustic communication, which increases the difficulty in energy efficiency and reliability of data transmission, for traditional WSN protocols are not suitable for underwater acoustic sensor networks (UASNs). Vector based forwarding (VBF) protocol is an energy efficient routing protocol for UASNs, by using the location information of nodes to limit the scale of flooding so that to save energy consumption and handle the mobility of nodes. In this paper a cross-layer protocol is proposed, which not only utilizes the VBF-based routing algorithm, but also considers the residual energy and the times of data relay in a cycle time to make more optimized decision whether a node will forward data or not. According to the simulation results, more evenly energy consumption and reliable data transmission are achieved, compared to previous VBF-based routing protocols for UASNs.

Abstract: Although critical for delivering resilient, secure, efficient, and easily changed IT systems, cross-technology, cross- layer quality defect detection in IT systems still faces hurdles. Two hurdles involve the absence of an absolute target architecture and the difficulty of apprehending multi-component anti-patterns. However, Static analysis and measurement technologies are now able to both consume contextual input and detect system-level anti-patterns. This paper will provide several examples of the information required to detect system-level anti-patterns using examples from the Common Weakness Enumeration repository maintained by MITRE Corp.

Abstract: Integrity of sensor readings or actuator commands is of paramount importance for a secure operation in the Internet-of-Things (IoT). Data from sensors might be stored, forwarded and processed by many different intermediate systems. In this paper we apply digital signatures to achieve end-to-end message level integrity for data in JSON. JSON has become very popular to represent data in the upper layers of the IoT domain. By signing JSON on the constrained device we extend the end-to-end integrity protection starting from the constrained device to any entity in the IoT data-processing chain. Just the JSON message's contents including the enveloped signature and the data must be preserved. We reached our design goal to keep the original data accessible by legacy parsers. Hence, signing does not break parsing. We implemented an elliptic curve based signature algorithm on a class 1 (following RFC 7228) constrained device (Zolertia Z1: 16-bit, MSP 430). Furthermore, we describe the challenges of end-to-end integrity when crossing from IoT to the Web and applications.

Abstract: Although P2P has been the main solution for live streaming distribution, the dynamic restricts the performance. Cloud computing is a new promising solution, which could be introduced as a supplement for P2P. It is a good direction on combining cloud computing and P2P to leverage the live streaming system performance. However, for seeking the design of the hybrid system architecture and deployment for good transmission performance, there has been no mature and integral solution so far. In this paper, we design a cloud-assisted P2P live streaming system called CPPStreaming by combing two state-of-the-art video distribution technologies: cloud computing and P2P. We introduce a two layer framework of CPPStreaming, including the cloud layer and P2P layer. As for the two layers respectively, we propose the corresponding formation and evolution method. For the system deployment, we formulate the leasing cloud servers strategy for an optimal problem and propose a greedy algorithm based on the heuristic solution for solving it. The experiment results show that our system can out perform two classical P2P live streaming systems, in terms of the transmission performance and the reduction of cross-region traffic.

Abstract: The provisioning of e-health and specifically m-health services requires the usage of advanced and reliable communication techniques to offer acceptable Quality of Experience (QoE) for doctors in the transfer of biomedical data between involved parties (i.e. flawless, or almost flawless, and prompt enough delivery) using wired or wireless access networks. To overcome the restrictions of conventional communication systems and to address the challenges imposed by wireless/mobile multimedia transfer and adaptation for healthcare applications, the CONCERTO project proposes a cross-layer optimized architecture with all the needed critical building blocks integrated for medical media content fusion, delivery and access, even on the move in emergency contexts. This paper describes the proposed reference system architecture, presenting the developed components and mechanisms in a comprehensive way, depicting and clarifying the overall picture and highlighting the impact of the CONCERTO approach in the healthcare domain. The evaluation of the proposed system is carried out both via simulation analysis and, more importantly, via validation involving real medical staff.

Abstract: The redundancy in English words helps the unauthorized entity to guess the cipher text. The DNA sequences do not follow such properties. It means the conversion of message to DNA sequences make it robust against attacks. This paper performs the DNA cryptography and then hides the DNA sequence in to the random frame of a video. The result analysis shows that the frame is imperceptible. The video seems to be same. The enhancement in PSNR value and reduction in MSE shows the effectiveness of the technique.

Abstract: Redundancy of words and characters in English language helps cryptanalysts in guessing the cipher text. DNA sequences do not follow any linguistic properties. Hence, translating any language first to DNA sequences and then applying cryptography technique upon it can prevent the attacks based on frequency analysis.. DNA cryptography is a branch of cryptography derived from DNA computing and based on difficult biological processes. In this paper, various operations that can be used in DNA computation along with DNA based cryptographic techniques have been discussed. Further, how advancement in DNA computation can bring a serious problem to traditional cryptographic system has also been explained. The work is concluded with the challenges to present DNA cryptographic system and future direction in this field.

Abstract: DNA computing is a new computational field which harnesses the immense parallelism, high density information and low power dissipation that brings probable challenges and opportunities to conventional cryptography. In recent years, many image encryption algorithms have been proposed using DNA solicit but many are not secure as such. In this regard, this paper proposes an improved and efficient algorithm to encrypt a grayscale image of any size based on DNA sequence addition operation. The original image is encrypted into two phases. In the first phase, the intermediate cipher is obtained by addition of the DNA sequence matrix and masking matrix. In the second phase, pixel values are scrambled to make it more robust. In this way the original image is encrypted. The results of simulated experiment and security analysis of the proposed image encryption algorithm, evaluated from histogram analysis and key sensitivity analysis, depicts that scheme not only can attain good encryption but can also hinder exhaustive attack and statistical attack. Thus, results are passable.

Abstract: “Sudoku” is the Japanese abbreviation of “Suuji wa dokushin ni kagiru”, which means “the numbers must occur only once”. It is a challenging and interesting puzzle that trains our mind logically. In recent years, solving Sudoku puzzles has become a widespread phenomenon. The problem of solving a given Sudoku puzzle finds numerous applications in the domain of Steganography, Visual Cryptography, DNA Computing, Watermarking, etc. Thus, solving the Sudoku puzzle in efficient manner is very important. However, incidentally all the existing Sudoku solving techniques are primarily either guess based heuristics or computation intensive soft computing methodologies. They also solve the puzzle by traversing on each and every individual cell. In this paper, a novel Sudoku solving technique is proposed which solves Sudoku puzzles without guessing a cell and by generating only the desired permutations among columns, which consist of only groups of cells.

Abstract: An efficient image encryption algorithm with improved image security has been developed by using chaotic function, deoxyribonucleic acid (DNA) sequencing and genetic algorithm (GA). A chaotic sequence of desired length is generated by using the logistic map function whose initial value is calculated using the secret key. A number of DNA masks are generated and these masks along with the chaotic sequences are used to encrypt the digital image. Finally genetic algorithm is employed to get the best mask for encryption. The proposed method can resist various types of attacks and produce high entropy and very low correlation between pixels.

Abstract: An image encryption algorithm based on chaotic theory and Deoxyribonucleic acid (DNA) sequencing is proposed here. Initially, two chaotic sequences are generated from the logistic map function, one for image permutation and other for image diffusion. The two internal secret keys derived from the 120 bit user defined secret key serve as the initial condition for the chaotic sequences. Both the image and the mask for diffusion are encoded into DNA sequences using the possible eight DNA complementary rules. After that, image permutation and diffusion operations are performed in the DNA domain. DNA XOR operation is used to carry out diffusion which significantly reduces the correlation between adjacent pixels of the plain image. Simulation results and performance analysis show that the proposed work has high security, large key space, and high key sensitivity and it is also able to resist all types of attacks.

Abstract: In today's world the life is very fast we want to do everything so quickly and easily without putting much physical and mental effort. With the advancement of technology we are provided with higher level of knowledge through the invention of different devices. However each technological innovation has its pros and cons. One of the emerging devise for biometric security system is Smartphone's we are using today. Today we cannot think of living without smart phones as they have become the part of our life. We depend on our phone for our so man day to day activities like paying bills connecting with friends and office, making money transaction. But using the traditional security features we cannot get appropriate security as anyone who knows the password to unlock my phone can get access to my phone. Using biometrics traits like fingerprint, voice, face, and iris one cannot get access to the device. In this paper we focus on how biometrics help in making the device more secure and fool proof and what were the lacking in the traditional methods of security system which give birth to the implementation of biometric security system.

Abstract: Existing Searchable Encryption (SE) solutions are able to handle simple Boolean search queries, such as single or multi-keyword queries, but cannot handle substring search queries over encrypted data that also involves identifying the position of the substring within the document. These types of queries are relevant in areas such as searching DNA data. In this paper, we propose a tree-based Substring Position Searchable Symmetric Encryption (SSP-SSE) to overcome the existing gap. Our solution efficiently finds occurrences of a substrings over encrypted cloud data. We formally define the leakage functions and security properties of SSP-SSE. Then, we prove that the proposed scheme is secure against chosen-keyword attacks that involve an adaptive adversary. Our analysis demonstrates that SSP-SSE introduces very low overhead on computation and storage.

Abstract: With the rapid development of network, more and more digital images need to be stored and communicated. Due to the openness and network sharing, the problems of digital image security become an important threat In this paper, we propose a novel gray image encryption algorithm based on chaotic mapping and DNA (Deoxyribonucleic Acid) encoding. We solve the error of irreversibility of a previous work, which can only encrypt the plain image, and cannot decrypt the cipher image with the correct secret key and can be attacked by the chosen plaintext. To make the algorithm invertible, we encode the input gray image by DNA encoding and generate a random matrix based on the logistic chaotic mapping. The DNA addition operation is conducted on the random matrix follow by the DNA complement operation guided by a random binary matrix generate by 2 logistic chaotic mapping sequences. We solve the problem of the irreversibility successfully. In addition, the algorithm can now resistant the several attacks such as chosen plaintext attack, brute-force attack, and statistic attack.

Abstract: A shared secret key based symmetric cryptographic algorithm using Diffie Hellman key sharing technique has been proposed in the paper. The shared secret key is used for encryption as well as decryption of the intended plain text. But, we are not transferring the original shared secret key through the channel. We are using Diffie Hellman key sharing technique to generate the shared secret key in both the side by exchanging the public key of the sender and receiver with each other through the channel DNA Hybridization technique has been used to produce the cipher text from the DNA sequence of plain text and the shared secret key. A numerical study with the basic parametric assumption confirms that the proposed cryptosystem is very scalable, secure and robust to use in real time system.

Abstract: Authentication is considered as one of the critical aspects of Information security to ensure identity. Authentication is generally carried out using conventional authentication methods such as text based passwords, but considering the increased usage of electronic services a user has to remember many id-password pairs which often leads to memorability issues. This inspire users to reuse passwords across e-services, but this practice is vulnerable to security attacks. To improve security strength, various authentication techniques have been proposed including two factor schemes based on smart card, tokens etc. and advanced biometric techniques. Graphical Image based authentication systems has received relevant diligence as it provides better usability by way of memorable image passwords. But the tradeoff between usability and security is a major concern while strengthening authentication. This paper proposes a novel two-way secure authentication scheme using DNA cryptography and steganography considering both security and usability. The protocol uses text and image password of which text password is converted into cipher text using DNA cryptography and embedded into image password by applying steganography. Hash value of the generated stego image is calculated using SHA-256 and the same will be used for verification to authenticate legitimate user.

Data Sanitization 2015 |
For security researchers, privacy protection during data mining is a major concern. Sharing information over the Internet or holding it in a database requires methods of sanitizing data so that personal information cannot be obtained. The methods described in the articles listed here include SQL injections, provenance workflows, itemset hiding, differential privacy, and a framework for a mathematical definition of privacy. The work cited here was presented in 2015.

Abstract: Security of published data cannot be less important as compared to unpublished data or the data which is not made public. Therefore, PII (Personally Identifiable Information) is removed and data sanitized when organizations recording large volumes of data publish that data. However, this approach of ensuring data privacy and security can result in loss of utility of that published data for knowledge discovery. Therefore, a balance is required between privacy and the utility needs of published data. In this paper we study this delicate balance by evaluating four data mining clustering techniques for knowledge discovery and propose two privacy/utility quantification parameters. We subsequently perform number of experiments to statistically identify which clustering technique is best suited with desirable level of privacy/utility while noise is incrementally increased by simultaneously degrading data accuracy, completeness and consistency.

Abstract: Cheap ubiquitous computing enables the collection of massive amounts of personal data in a wide variety of domains. Many organizations aim to share such data while obscuring features that could disclose entities or other sensitive information. Much of the data now collected exhibits weak structure (e.g., natural language text) and machine learning approaches have been developed to identify and remove sensitive entities in such data. Learning-based approaches are never perfect and relying upon them to sanitize data can leak sensitive information as a consequence. However, a small amount of risk is permissible in practice, and, thus, our goal is to balance the value of data published and the risk of an adversary discovering leaked sensitive information. We model data sanitization as a game between1) a publisher who chooses a set of classifiers to apply to data and publishes only instances predicted to be non-sensitive and 2) an attacker who combines machine learning and manual inspection to uncover leaked sensitive entities (e.g., personal names). We introduce an iterative greedy algorithm for the publisher that provably executes no more than a linear number of iterations, and ensures a low utility for a resource-limited adversary. Moreover, using several real world natural language corpora, we illustrate that our greedy algorithm leaves virtually no automatically identifiable sensitive instances for a state-of-the-art learning algorithm, while sharing over 93% of the original data, and complete after at most 5 iterations.

Abstract: Cross site scripting (XSS) vulnerability is among the top 10 web application vulnerabilities based on survey by Open Web Applications Security Project of 2013 [9]. The XSS attack occurs when web based application takes input from users through web pages without validating them. An attacker or hacker uses this to insert malicious scripts in web pages through such inputs. So, the scripts can perform malicious actions when a client visits the vulnerable web pages. This study concentrates on various security measures for removal of XSS from web applications (say defensive coding technique) and their issues of defensive technique based on that measures is reported in this paper.

Abstract: We present a transformation procedure for large scale individual level data that produces output data in which no linear combinations of the resulting attributes can yield the original sensitive attributes from the transformed data. In doing this, our procedure eliminates all linear information regarding a sensitive attribute from the input data. The algorithm combines principal components analysis of the data set with orthogonal projection onto the subspace containing the sensitive attribute(s). The algorithm presented is motivated by applications where there is a need to drastically `sanitize' a data set of all information relating to sensitive attribute(s) before analysis of the data using a data mining algorithm. Sensitive attribute removal (sanitization) is often needed to prevent disparate impact and discrimination on the basis of race, gender, and sexual orientation in high stakes contexts such as determination of access to loans, credit, employment, and insurance. We show through experiments that our proposed algorithm outperforms other privacy preserving techniques by more than 20 percent in lowering the ability to reconstruct sensitive attributes from large scale data.

Abstract: Severe privacy leakage in the AOL search log incident has attracted considerable worldwide attention. However, all the web users' daily search intents and behavior are collected in such data, which can be invaluable for researchers, data analysts and law enforcement personnel to conduct social behavior study [14], criminal investigation [5] and epidemics detection [10]. Thus, an important and challenging research problem is how to sanitize search logs with strong privacy guarantee and sufficiently retained utility. Existing approaches in search log sanitization are capable of only protecting the privacy under a rigorous standard [24] or maintaining good output utility [25] . To the best of our knowledge, there is little work that has perfectly resolved such tradeoff in the context of search logs, meeting a high standard of both requirements. In this paper, we propose a sanitization framework to tackle the above issue in a distributed manner. More specifically, our framework enables different parties to collaboratively generate search logs with boosted utility while satisfying Differential Privacy. In this scenario, two privacy-preserving objectives arise: first, the collaborative sanitization should satisfy differential privacy; second, the collaborative parties cannot learn any private information from each other. We present an efficient protocol -Collaborative sEarch Log Sanitization (CELS) to meet both privacy requirements. Besides security/privacy and cost analysis, we demonstrate the utility and efficiency of our approach with real data sets.

Abstract: Due to limited time and resources, web software engineers need support in identifying vulnerable code. A practical approach to predicting vulnerable code would enable them to prioritize security auditing efforts. In this paper, we propose using a set of hybrid (static+dynamic) code attributes that characterize input validation and input sanitization code patterns and are expected to be significant indicators of web application vulnerabilities. Because static and dynamic program analyses complement each other, both techniques are used to extract the proposed attributes in an accurate and scalable way. Current vulnerability prediction techniques rely on the availability of data labeled with vulnerability information for training. For many real world applications, past vulnerability data is often not available or at least not complete. Hence, to address both situations where labeled past data is fully available or not, we apply both supervised and semi-supervised learning when building vulnerability predictors based on hybrid code attributes. Given that semi-supervised learning is entirely unexplored in this domain, we describe how to use this learning scheme effectively for vulnerability prediction. We performed empirical case studies on seven open source projects where we built and evaluated supervised and semi-supervised models. When cross validated with fully available labeled data, the supervised models achieve an average of 77 percent recall and 5 percent probability of false alarm for predicting SQL injection, cross site scripting, remote code execution and file inclusion vulnerabilities. With a low amount of labeled data, when compared to the supervised model, the semi-supervised model showed an average improvement of 24 percent higher recall and 3 percent lower probability of false alarm, thus suggesting semi-supervised learning may be a preferable solution for many real world applications where vulnerability data is missing.

Yamaguchi, F.; Maier, A.; Gascon, H.; Rieck, K., "Automatic Inference of Search Patterns for Taint-Style Vulnerabilities," in Security and Privacy (SP), 2015 IEEE Symposium on, pp. 797-812, 17-21 May 2015. doi: 10.1109/SP.2015.54
Abstract: Taint-style vulnerabilities are a persistent problem in software development, as the recently discovered "Heart bleed" vulnerability strikingly illustrates. In this class of vulnerabilities, attacker-controlled data is passed unsanitized from an input source to a sensitive sink. While simple instances of this vulnerability class can be detected automatically, more subtle defects involving data flow across several functions or project-specific APIs are mainly discovered by manual auditing. Different techniques have been proposed to accelerate this process by searching for typical patterns of vulnerable code. However, all of these approaches require a security expert to manually model and specify appropriate patterns in practice. In this paper, we propose a method for automatically inferring search patterns for taint-style vulnerabilities in C code. Given a security-sensitive sink, such as a memory function, our method automatically identifies corresponding source-sink systems and constructs patterns that model the data flow and sanitization in these systems. The inferred patterns are expressed as traversals in a code property graph and enable efficiently searching for unsanitized data flows -- across several functions as well as with project-specific APIs. We demonstrate the efficacy of this approach in different experiments with 5 open-source projects. The inferred search patterns reduce the amount of code to inspect for finding known vulnerabilities by 94.9% and also enable us to uncover 8 previously unknown vulnerabilities.

Abstract: Taint analysis determines whether values from untrusted or private sources may flow into security-sensitive or public sinks, and can discover many common security vulnerabilities in both Web and mobile applications. Static taint analysis detects suspicious data flows without running the application and achieves a good coverage. However, most existing static taint analysis tools only focus on discovering taint paths from sources to sinks and do not concern about the requirements of analysts for sanitization check and exploration. The sanitization can make a taint path no more dangerous but should be checked or explored by analysts manually in many cases and the process is very costly. During our preliminary study, we found that many statements along taint paths are not relevant to the sanitization and there are a lot of redundancies among taint paths with the same source or sink. Based on these two observations, we have designed and implemented the taint path slicing and aggregation algorithms, aiming at mitigating the workload of the analysts and helping them get a better comprehension of the taint behaviors of target applications. Experimental evaluations on real-world applications show that our proposed algorithms can reduce the taint paths effectively and efficiently.

Abstract: Trajectory data, i.e., human mobility traces, is extremely valuable for a wide range of mobile applications. However, publishing raw trajectories without special sanitization poses serious threats to individual privacy. Recently, researchers begin to leverage differential privacy to solve this challenge. Nevertheless, existing mechanisms make an implicit assumption that the trajectories contain a lot of identical prefixes or n-grams, which is not true in many applications. This paper aims to remove this assumption and propose a differentially private publishing mechanism for more general time-series trajectories. One natural solution is to generalize the trajectories, i.e., merge the locations at the same time. However, trivial merging schemes may breach differential privacy. We, thus, propose the first differentially-private generalization algorithm for trajectories, which leverage a carefully-designed exponential mechanism to probabilistically merge nodes based on trajectory distances. Afterwards, we propose another efficient algorithm to release trajectories after generalization in a differential private manner. Our experiments with real-life trajectory data show that the proposed mechanism maintains high data utility and is scalable to large trajectory datasets.

Abstract: Data Mining allows large database owners to extract useful knowledge that could not be deduced with traditional approaches like statistics. However, these sometimes reveal sensitive knowledge or preach individual privacies. The term sanitization is given to the process of changing original database into another one from which we can mine without exposing sensitive knowledge. In this paper, we give a detailed explanation of some heuristic approaches for this purpose. We applied them on a number of publically available datasets and examine the results.

Abstract: Some of the most rampant problems in software security originate from improper input validation. This is partly due to ad hoc approaches taken by software developers when dealing with user inputs. Therefore, it is a crucial research question in software security to ask how to effectively apply well-known input validation and sanitization techniques against security attacks exploiting the user input-related weaknesses found in software. This paper examines the current ways of how input validation is conducted in major open-source projects and attempts to confirm the main source of the problem as these ad hoc responses to the input validation-related attacks such as SQL injection and cross-site scripting (XSS) attacks through a case study. In addition, we propose a more systematic software security approach by promoting the adoption of proactive, architectural design-based solutions to move away from the current practice of chronic vulnerability-centric and reactive approaches.

Abstract: Large datasets of real network flows acquired from the Internet are an invaluable resource for the research community. Applications include network modeling and simulation, identification of security attacks, and validation of research results. Unfortunately, network flows carry extremely sensitive information, and this discourages the publication of those datasets. Indeed, existing techniques for network flow sanitization are vulnerable to different kinds of attacks, and solutions proposed for microdata anonymity cannot be directly applied to network traces. In our previous research, we proposed an obfuscation technique for network flows, providing formal confidentiality guarantees under realistic assumptions about the adversary's knowledge. In this paper, we identify the threats posed by the incremental release of network flows, we propose a novel defense algorithm, and we formally prove the achieved confidentiality guarantees. An extensive experimental evaluation of the algorithm for incremental obfuscation, carried out with billions of real Internet flows, shows that our obfuscation technique preserves the utility of flows for network traffic analysis.

Abstract: In this paper we propose a new approach to prevent and detect potential cross-site scripting attacks. Our method called Buffer Based Cache Check, will utilize both the server-side as well as the client-side to detect and prevent XSS attacks and will require modification of both in order to function correctly. With Cache Check, instead of the server supplying a complete whitelist of all the known trusted scripts to the mobile browser every time a page is requested, the server will instead store a cache that contains a validated “trusted” instance of the last time the page was rendered that can be checked against the requested page for inconsistencies. We believe that with our proposed method that rendering times in mobile browsers will be significantly reduced as part of the checking is done via the server, and fewer checking within the mobile browser which is slower than the server. With our method the entire checking process isn't dumped onto the mobile browser and as a result the mobile browser should be able to render pages faster as it is only checking for “untrusted” content whereas with other approaches, every single line of code is checked by the mobile browser, which increases rendering times.

Abstract: While significant bodies of work exist for sandboxing potentially malicious software and for sanitizing input, there has been little investigation into using binary editing software to perform either of these tasks. However, because binary editors do not require source code and can modify the software, they can generate secure versions of arbitrary binaries and provide better control over the software than existing approaches. In this paper, we explore the application of the binary editing library Dyninst to both the sandboxing and sanitization problems. We also create a prototype of a more advanced graphical tool to perform these tasks. Finally, we lay the groundwork for more complex and functional tools to solve these problems.

Data in Motion and Data at Rest 2015 |
Data protection has distinguished between data in motion and data at rest for more than a decade. Research into these areas continues with the proliferation of cloud and mobile technologies. For the Science of Security community, the topic relates to resilience and composability. The articles cited here, separated by motion and rest, were offered in 2015.

Abstract: With high and growing supply of Database-as-a-Service solutions from cloud platform vendors, many enterprises still show moderate to low demand for them. Even though migration to a DaaS solution might result in a significantly reduced bill for IT maintenance, data security and privacy issues are among the reasons of low popularity of these services. Such a migration is also often only justified if it could be done seamlessly, with as few changes to the system as possible. Transparent Data Encryption could help, but solutions for TDE shipped with major database systems are limited to securing only data-at-rest, and appear to be useless if the machine could be physically accessed by the adversary, which is a probable risk when hosting in the cloud. This paper proposes a different approach to TDE, which takes into account cloud-specific risks, extends encryption to cover data-in-use and partly data-in-motion, and is capable of executing large subsets of SQL including heavy relational operations, complex operations over attributes, and transactions.

Althobaiti, A.; Calyam, P.; Akella, R.; Vallabhaneni, P., "Data Integrity Protection through Security Monitoring for Just-in-Time News Feeds," in Cloud Networking (CloudNet), 2015 IEEE 4th International Conference on, pp. 184-190, 5-7 Oct. 2015. doi: 10.1109/CloudNet.2015.7335303
Abstract: There has recently been a major shift in news related media consumption trends and readers are increasingly relying on just-in-time news feeds versus the traditional newspaper print medium. Cloud-networked infrastructures are being setup by the media companies to aggregate news feeds from affiliates, and to meet the elastic demands of Internet-scale users accessing news feeds. However, cyber attacks could compromise these just-in-time news feed services and hackers could particularly launch data integrity as well as denial-of-service attacks that: (a) tarnish the reputation of media companies and (b) impact the service availability for users. In this paper, we describe data integrity and availability checking techniques to protect just-in-time news feed services against cyber attacks in use cases such as: (a) “Data-in-Motion” - when obtaining just-in-time news feeds (e.g., RSS feeds) from affiliates and (b) “Data-at-Rest” - when compiled news feeds reside within cloud-networked infrastructure for real-time premium subscriber access. Using concepts of distributed trust and anomaly detection and a realistic testbed environment in the DeterLab infrastructure, we show the impact of the different cyber attacks and propose solutions to defend against them.

Abstract: Cloud service providers are offering the popular Hadoop analytics platform following an "as-a-service" model, i.e. clusters of machines in their cloud infrastructures pre-configured with Hadoop software. Such offerings lower the cost and complexity of deploying a comparable system on-premises, however security considerations and in particular data confidentiality hamper wider adoption of such services by enterprises that handle data of sensitive nature. In this paper, we describe our efforts in providing security for data-at-rest (i.e. data that is stored) when Hadoop is offered as a cloud service. We analyze the requirements and architecture for such service and further describe a new distributed file system that we developed for Hadoop called SDFS, towards supporting this premise. We analyze parameter tuning for SDFS and through experiments on a real test-bed we evaluate its performance. We further present simulation results that explore the parameter space and can guide tuning.

Abstract: Encryption of data residing on the permanent memory of a device, also known as On-Device Encryption (ODE), is a well studied problem with many popular software available these days. We consider the adversary who is capable of taking one RAM snapshot (e.g: Cold Boot Attack) when the device is in locked state. Writing data securely, when the device is in locked state can be handled in the presence of this strong adversary, by employing public key encryption techniques. When it comes to reading of data from a locked device, it is not known until now, whether it is possible. In this paper, we state the impossibility of performing the read operation securely, when the device is in locked state. Moreover, we propose a new forward secure ODE scheme which supports secure writing in locked state and is more efficient when compared to the public key based solution. We have proposed the security model for forward secure ODE and proved the security of our scheme in the proposed security model.

Abstract: Recent years have seen a flurry of activity in the area of efficient and secure file systems for cloud storage, and also in the area of memory protection for secure processors. Both scenarios use cryptographic methods for data protection. Here, we consider the middle ground: the problem of using cryptographic methods to protect data integrity and confidentiality on a system with two strongly isolated execution environments, specifically an ARM TrustZone system with a Trusted Execution Environment. We introduce the Secure Block Device, a secure, easy to use, flexible, efficient, and widely applicable minimal Trusted Computing Base solution to provide data confidentiality and integrity for Data at Rest. The Secure Block Device is an open source C software library that uses a Merkle-Tree in conjunction with a selectable Authenticated Encryption scheme to provide an easy to integrate solution for applications that require fast and secure random access to data, but not a fully fledged file system. It was designed for Trusted Applications running in a Trusted Execution Environment that already have secure storage for cryptographic keys, but no secure general purpose data store. Beyond that, the Secure Block Device is applicable in all similar scenarios. We evaluate the Secure Block Device by using it as the core component in a secure storage Trusted Application that uses the ARM TrustZone Trusted Execution Environment to provide a confidential and integrity protected block device to the normal world OS.

Abstract: There has recently been a major shift in news related media consumption trends and readers are increasingly relying on just-in-time news feeds versus the traditional newspaper print medium. Cloud-networked infrastructures are being setup by the media companies to aggregate news feeds from affiliates, and to meet the elastic demands of Internet-scale users accessing news feeds. However, cyber attacks could compromise these just-in-time news feed services and hackers could particularly launch data integrity as well as denial-of-service attacks that: (a) tarnish the reputation of media companies and (b) impact the service availability for users. In this paper, we describe data integrity and availability checking techniques to protect just-in-time news feed services against cyber attacks in use cases such as: (a) “Data-in-Motion” - when obtaining just-in-time news feeds (e.g., RSS feeds) from affiliates and (b) “Data-at-Rest” - when compiled news feeds reside within cloud-networked infrastructure for real-time premium subscriber access. Using concepts of distributed trust and anomaly detection and a realistic testbed environment in the DeterLab infrastructure, we show the impact of the different cyber attacks and propose solutions to defend against them.

Abstract: Data quality is a challenging problem in many real world application domains. While a lot of attention has been given to detect anomalies for data at rest, detecting anomalies for streaming applications still largely remains an open problem. For applications involving several data streams, the challenge of detecting anomalies has become harder over time, as data can dynamically evolve in subtle ways following changes in the underlying infrastructure. In this paper, we describe and empirically evaluate an online anomaly detection pipeline that satisfies two key conditions: generality and scalability. Our technique works on numerical data as well as on categorical data and makes no assumption on the underlying data distributions. We implement two metrics, relative entropy and Pearson correlation, to dynamically detect anomalies. The two metrics we use provide an efficient and effective detection of anomalies over high velocity streams of events. In the following, we describe the design and implementation of our approach in a Big Data scenario using state-of-the-art streaming components. Specifically, we build on Kafka queues and Spark Streaming for realizing our approach while satisfying the generality and scalability requirements given above. We show how a combination of the two metrics we put forward can be applied to detect several types of anomalies ??? like infrastructure failures, hardware misconfiguration or user-driven anomalies ??? in large-scale telecommunication networks. We also discuss the merits and limitations of the resulting architecture and empirically evaluate its scalability on a real deployment over live streams capturing events from millions of mobile devices.

Abstract: Major Golf and Grand Slam Tennis tournaments such as Australian Open, The Masters, Roland Garros, United States Golf Association (USGA), Wimbledon, and United States Tennis Association (USTA) United States (US) Open provide real-time and historical sporting information to immerse a global fan base in the action. Each tournament provides realtime content, including streaming video, game statistics, scores, images, schedule of play, and text. Due to the game popularities, some of the web servers are heavily visited and some are not, therefore, we need a method to autonomously provision servers to provide a smooth user experience. Predictive Cloud Computing (PCC) has been developed to provide a smart allocation/deallocation of servers by combining ensembles of forecasts and predictive modeling to determine the future origin demand for web site content. PCC distributes processing through analytical pipelines that correlate streaming data, such as scores, media schedules, and player brackets with a future-simulated tournament state to measure predicted demand spikes for content. Social data streamed from Twitter provides social sentiment and popularity features used within predictive modeling. Data at rest, such as machine logs and web content, provide additional features for forecasting. While the duration of each tournament varies, the number of origin website requests range from 29,000 to 110,000 hits per minute. The PCC technology was developed and deployed to all Grand Slam tennis events and several major golf tournaments that took place in 2013 and to the present, which has decreased wasted computing consumption by over 50%. We propose a novel forecasting ensemble that includes residual, vector, historical, partial, adjusted, cubic and quadratic forecasters. In addition, we present several predictive models based on Multiple Regression as inputs into several of these forecasters. We conclude by empirically demonstrating that the predictive cloud technology is able- to forecast the computing load on origin web servers for professional golf and tennis tournaments.

Abstract: In this paper, a new discrete-time adaptive control scheme for controlling robot manipulators is proposed. The objective is to control position of a robot manipulator end effector in the presence of uncertainties caused by unknown fixed or time-varying payload. For simplicity, the unknown payload is considered as the only unknown factor and the data in use is sampled from the true continuous-time plant with constant fixed sampling interval. We estimate the payload according to the available history information and design a discrete-time adaptive controller based on the estimation of the external payload. The adaptive estimator adopted in the adaptive controller only uses one step history and is capable of fast adaptation. The simulation results demonstrated that the new controller can yield a satisfactory tracking performance in the presence of payload uncertainties.

Abstract: Cybersecurity measures require that a balance be achieved between technical feasibility and economic feasibility and that this balance addresses the risks expected to be present at a substation. Further, cybersecurity measures must be designed and implemented in such a manner that access and operation to legitimate activities is not impeded, particularly during times of emergency or restoration activity. This standard presents a balance of the above factors.

Abstract: In this paper, we present a privacy-preserving protocol between an energy provider and smart meters. Many details about the life of customers can be inferred from fine-grained information on their energy consumption. Different from other state-of-the-art protocols, the presented protocol addresses this issue as well as the integrity of electricity bills. Therefore, our protocol provides secure aggregation of measured consumption per round of measurement and verifiable billing after any period. Aggregation of measured consumption ensures that energy suppliers know the consolidated consumption of their customers. Verifiable billing ensures fairness for customers and their energy supplier. We adapt a homomorphic encryption scheme based on elliptic curve cryptography to efficiently protect the data series of measurements that are collected by smart meters. Moreover, energy suppliers can detect and locate energy loss or fraud in the power grid while retaining the privacy of all consumers.

Abstract: Wireless Sensor Network (WSN) be a large scale network with thousands of tiny sensors moreover is of utmost importance as it is used in real time applications. Currently WSN is required for up-to-the-minute applications which include Internet of Things (IOT), Smart Card, Smart Grid, Smart Phone and Smart City. However the greatest issue in sensor network is secure communication for which key management is the primary objective. Existing key management techniques have many limitations such as prior deployment knowledge, transmission range, insecure communication and node captured by the adversary. The proposed novel Track-Sector Clustering (TSC) and Hyper Elliptic Curve Cryptography (HECC) provides better transmission range and secure communication. In TSC, the overall network is separated into circular tracks and triangular sectors. Power Aware Routing Protocol (PARP) was used for routing of data in TSC, which reduces the delay with increased packet delivery ratio. Further for secure routing HECC was implemented with 80 bits key size, which reduces the memory space and computational overhead than the existing Elliptic Curve Cryptography (ECC) key management scheme.

Abstract: In smart grid, Advanced Metering Infrastructure (AMI) system provides measuring, storing, analyzing, and utilizing energy consumption data. It enables a link between customers and electric power utilities. The AMI is also responsible for transmitting requests, commands, pricing-information and software updates from the authorized parties to the smart meters. As the AMI security threats from inside and outside grow exponentially; confidentiality, authentication, integrity and non-repudiation security services should be deployed to overcome possible threats. In this paper we give an overview on the main components and security requirements of the AMI and present possible security solutions. Then we propose an identity based security architecture, namely a signcryption scheme for smart metering infrastructure to provide necessary security services by taking advantage of identity based cryptography to ensure efficiency in addition to security through eliminating the cost for generation and managing certificates.

Abstract: Smart grid is a modern electrical grid that utilizes Information and Communication Technologies (ICT) and information networks. Growing attraction in Electric Vehicles (EV) shall likely provide a fundamental shift not only in transportation sector but also in the existing electrical grid infrastructure. In Vehicle-to-Grid (V2G) network, participating EVs can be used to store energy and supply this energy back to the power grid when required. To realize proper deployment of V2G network, charging infrastructure having various entities such as charging facility, clearinghouse, and energy provider has to be constructed. So use of Public key infrastructure (PKI) is indispensable for provisioning security solutions in V2G networks. The ISO/IEC 15118 standard is ascribed that incorporates X.509 PKI solution for V2G network. However, as traditional X.509 based PKI for V2G network has several shortcomings, we have proposed a multi-domain PKI model for V2G network that is built on elliptic curve cryptography and a self-certified public key technique having implicit certificate. We illustrate that the proposed solutions outperform the existing ones.

Abstract: In the prevailing smart grid, the Home Area Network (HAN) will become a critical infrastructure component at the consumer premises. The HAN provides the electricity infrastructure with a bi-directional communication infrastructure that allows monitoring and control of electrical appliances. HANs are typically equipped with wireless sensors and actuators, built from resource-constrained hardware devices, that communicate by using open standard protocols. This raises concerns on the security of these networked systems. Because of this, securing a HAN to a proper degree becomes an increasingly important task. In this paper, a security model, where an adversary may exploit the system both during HAN setup as well as during operations of the network, is considered. We propose a scheme for secure bootstrapping of wireless HAN devices based on Identity-Based Cryptography (IBC). The scheme minimizes the number of exchanged messages needed to establish a session key between HAN devices. The feasibility of the approach is demonstrated from a series of prototype experiments.

Abstract: Elliptic Curve Cryptography (ECC) has been the focus of much recent attention since it offers the highest security per bit of any known public key cryptosystem. This benefit of smaller key sizes makes ECC particularly attractive for constrained devices, since its implementation requires less memory and processing power. The present work gives a description of a hardware implementation of an F2m elliptic curve cryptographic processor using field programmable gate array circuit technology. We provide simulation and implementation results related to ECC processor using the National Institute of Standards and Technology (NIST) recommended curve.

Abstract: Biometric systems are systems which have an automated method to measure or analyze biological data, extracting features from the acquired data and comparing it against the templates set in the database. Many authentication schemes involving different biometric systems initialize several identification- and verification-based security methods, and this paper discusses a system which provides secure verification to incorporate the method with elliptical curve cryptography that works on following two points, viz. preventing an elliptic curve and a key using elliptical curve cryptography and the blending of biometric modality. The paper also discusses different approaches to multi-model biometric systems, the levels of fusion that are plausible and the integration of strategies that can be adopted to consolidate information. The unimodal biometric system faces many difficulties, like spooling, attacks, noisy data, etc., but the combination of two or more biometric modalities recognizes anything in a single identification.

Abstract: Pseudo-random numbers generators (PRNG) are one of the main security tools in Radio Frequency IDentification (RFID) technology. Thus, a weak internal embedded generator can directly cause the entire application to be insecure and it makes no sense to employ robust protocols for the security issue. In this paper, we propose a new PRNG constructed by randomly selecting points from two elliptic curves, suitable for ECC based applications. The main contribution of this work is the increasing of the generator internal states by extending the set of its output realizations to two curves randomly selected. The main advantages of this PRNG in comparison to previous works are the large periodicity, a better distribution of the generated sequences and a high security level based on the elliptic curve discrete logarithm problem (ECDLP). Further, the proposed PRNG has passed the different Special Publication 800-22 NIST statistical test suite. Moreover, the proposed PRNG presents a scalable architecture in term of security level and periodicity at the expense of increasing the computation complexity. Thus, it can be adapted for ECC based cryptosystems such as RFID tags and sensors networks and other applications like computer physic simulations, and control coding.

Abstract: Wireless Sensor Networks (WSN) are spatially distributed nodes monitoring physical or environmental conditions such as temperature, pressure, sound, light etc using sensors. The sensed data is cooperatively passed through a series of nodes in a network to a main base-station (BS) where it is analysed by the user. The data is communicated over a wireless channel between the nodes and since wireless channel has minimum security, the data has to be communicated in a secure manner. Different encryption techniques can be applied to transmit the data securely. This work provides an efficient implementation of Elliptic Curve Digital Signature Algorithm (ECDSA) using SHA-512 algorithm on an IRIS mote. The ECDSA does not actually encrypt the data but provides a means to check the integrity of the received data. If the received data has been modified by an attacker, the ECDSA detects it and signals to the transmitter for retransmission. The SHA-512 algorithm is the hash algorithm used in the ECDSA and is implemented for an 8-bit architecture. The SHA-512 algorithm is chosen as it provides better security than its predecessors.

Abstract: The challenge of providing security for Mobile Ad-hoc Networks (MANETs) due to the inherent problems regarding to the use of mobile devices and nonexistence of fixed infrastructures, made them one of the significant topics in security and cryptography research area. In this way, several works have been done to propose lightweight and less energy consuming protocols. However, the use of an expensive cryptographic operation named Bilinear Pairing made the mentioned schemes heavy for such resource constrained environments. In this paper, we could propose an efficient public key authentication scheme over an elliptic curve based algebraic group rather than Bilinear Pairings. The results show that our proposed scheme requires less complex operations in compare with other related ones.

Abstract: Elliptic curve cryptography has established itself as a perfect cryptographic tool in embedded environment because of its compact key sizes and security strength at par with that of any other standard public key algorithms. Several FPGA implementations of ECC processor suited for embedded system have been consistently proposed, with a prime focus area being space and time complexities. In this paper, we have modified double point multiplication algorithm and replaced traditional Karatsuba multiplier in ECC processor with a novel modular multiplier. Designed Modular multiplier follows systolic approach of processing the words. Instead of processing vector polynomial bit by bit or in parallel, proposed multiplier recursively processes data as 16-bit words. This multiplier when employed in ECC processor reduces drastically the total area utilization. The complete modular multiplier and ECC processor module is synthesized and simulated using Xilinx 14.4 software. Experimental findings show a remarkable improvement in area efficiency, when comparing with other such architectures.

Abstract: Public Key Regime (PKR) was proposed as an alternative to certificate based PKI in securing Vehicular Networks (VNs). It eliminates the need for vehicles to append their certificate for verification because the Road Side Units (RSUs) serve as Delegated Trusted Authorities (DTAs) to issue up-to-date public keys to vehicles for communications. If a vehicle's private/public key needs to be revoked, the root TA performs real time updates and disseminates the changes to these RSUs in the network. Therefore, PKR does not need to maintain a huge Certificate Revocation List (CRL), avoids complex certificate verification process and minimizes the high latency. However, the PKR scheme is vulnerable to Denial of Service (DoS) and collusion attacks. In this paper, we study these attacks and propose a pre-authentication mechanism to secure the PKR scheme. Our new scheme is called the Secure Public Key Regime (SPKR). It is based on the Schnorr signature scheme that requires vehicles to expend some amount of CPU resources before RSUs issue the requested public keys to them. This helps to alleviate the risk of DoS attacks. Furthermore, our scheme is secure against collusion attacks. Through numerical analysis, we show that SPKR has a lower authentication delay compared with the Elliptic Curve Digital Signature (ECDSA) scheme and other ECDSA based counterparts.

Abstract: Effective network security may targets a plenty of threats and also avoids them from entering or opening out on a network. An attack in Mobile Ad hoc NETwork (MANET) is due to unreliability, unfixed topology, limited battery power and lack of centralized control. The first line of defense solutions is Encryption and authentication which are not adequate to protect MANETs from packet dropping attacks. Existing IDSs for MANETS depend on the Watchdog technique. In existing system Researchers main attraction is on designing new prevention, detection and response mechanism for MANETs. The scheme will identify, supervise and observe the malicious nodes without adjusting the performances in the network. The motivation is to overcome the issues such as “limited transmission power, packet dropping, receiver collision and false misbehavior reports” generation of the Watchdog system. In this paper, we proposed a new the Modified Version of EAACK based IDS that is used to overcome the MANET attacks. Elliptic Curve Digital signature Algorithm (ECDSA) is use to authenticate the acknowledgment packets used in the propose work to overcome drawbacks in the security level.

Abstract: In this paper, we present a novel concept in proxy signature by introducing a trusted proxy agent called mediator together with a proxy signer, which enables an efficient revocation of signing capability within the delegation period, by controlling the signing capability of proxy signer even before/after generating the signature by the designated proxy signer. We describe a secure designated proxy signature scheme with revocation based on elliptic curve discrete logarithmic problem. Further, we define a random oracle based security model to prove the security of the proposed scheme under an adaptive-chosen-message attack and an adaptive-chosen-warrant attack.

Abstract: In this paper, we present the implementation of a multi-mode crypto-coprocessor, which can support three different public-key cryptography (PKC) engines (NTRU, TTS, Pairing) used in post-quantum and identity-based cryptosystems. The PKC-based security protocols are more energy-efficient because they usually require less communication overhead than symmetric-key-based counterparts. In this work, we propose the first-of-its-kind tri-mode PKC coprocessor for secured data transmission in Internet-of-Things (IoT) systems. For the purpose of low energy consumption, the crypto-coprocessor incorporates three design features, including 1) specialized instruction set for the multi-mode cryptosystems, 2) a highly parallel arithmetic unit for cryptographic kernel operations, and 3) a smart scheduling unit with intelligent control mechanism. By utilizing the parallel arithmetic unit, the proposed crypto-coprocessor can achieve about 50% speed up. Meanwhile, the smart scheduling unit can save up to 18% of the total latency. The crypto-coprocessor was implemented with AHB interface in TSMC 90nm CMOS technology, and the die size is only 1.96 mm2. Furthermore, our chip is integrated with an ARM-based system-on-chip (SoC) platform for functional verification.

Abstract: A Wireless Sensor Network (WSN) is a versatile sensing system suitable to cover a wide variety of applications. Power efficiency, security and reliability are the major areas of concern in designing WSNs[3][7]. More-over, one of the most important issues in WSN design is to assure the reliability of the collected data which often involve security issues in the wireless communications. This project mainly focused on development of hybrid encryption scheme which combines a symmetric and asymmetric encryption algorithms for secure key exchange and enhanced cipher text security. This paper comments on comparison of performance in terms of bit error rate for symmetric, Asymmetric and hybrid encryption schemes implemented in wireless sensor networks. Test Results shows decrease in bit error rate by using hybrid encryption scheme as compare to symmetric and asymmetric schemes alone. Increase in number of sensors further minimizes bit error rate and improves performance. Alamouti codes with Space time block codes are most widely used transmission mechanism in WSN. Extended space time block codes (ECBSTBC) have better signal to noise ratio improvement when compared with sensor selection scheme. Proposed system uses ECBSTBC codes for transmission[8].

Abstract: This paper presents an approach to incorporate strong security in deploying Internet of Things (IoT) for smart home system, together with due consideration given to user convenience in operating the system. The IoT smart home system runs on conventional wifi network implemented based on the AllJoyn framework, using an asymmetric Elliptic Curve Cryptography to perform the authentications during system operation. A wifi gateway is used as the center node of the system to perform the system initial configuration. It is then responsible for authenticating the communication between the IoT devices as well as providing a mean for the user to setup, access and control the system through an Android based mobile device running appropriate application program.

Abstract: Vehicular Ad-hoc Network (VANET) cloud, a hybrid technology, provides several computational services to minimize traffic congestion, travelling time, accidents, and environmental pollution. In the proposed work, the concept of VANET cloud is used for helping the regulatory authorities in identifying the vehicles violating the traffic rules through sensors included as part of On Board Unit (OBU). When the vehicle is on fly the sensor values are periodically transferred to the cloud, controlled by the traffic police. A novel concept called Transient Ticket (TT) has been used to minimize the time and the cost of distributing Certificate Revocation List (CRL) to the vehicles. The proposed scheme also ensures utmost verification of identity, authenticity, confidentiality and integrity of the communication parties and messages exchanged. The work has been simulated using NS3 network simulator and Google App Engine (GAE). All the generated keys, TTs and the exchanged messages have been securely stored in the GAE for the ease of accessibility and processing. The results show that the proposed approach consumes very less time with respect to the generation of keys, exchange of messages, verification of authenticity and the generation of TT without compromising security.

Abstract: One of the most effective way to prevent unauthorized and corrupted message being forwarded in wireless sensor network. But there is high computational and communication overhead in addition to lack of scalability and resilience to node compromise attacks. So to address these issues, a polynomial-based scheme was recently introduced. However, this scheme and its extensions all have the weakness of a built-in threshold determined by the degree of the polynomial. when the number of messages transmitted is larger than this threshold, the adversary can fully recover the polynomial. In the existing system, an unconditionally secure and efficient source anonymous message authentication (SAMA) scheme is presented which is based on the optimal modified Elgamal signature (MES) scheme on elliptic curves. This MES scheme is secure against adaptive chosen-message attacks in the random oracle model. This scheme enables the intermediate nodes to authenticate the message so that all corrupted message can be detected and dropped to conserve the sensor power. While achieving compromise resiliency, flexible-time authentication and source identity protection, this scheme does not have the threshold problem. While enabling intermediate nodes authentication, this scheme allows any node to transmit an unlimited number of messages without suffering the threshold problem. But by using this method the black hole and gray hole attacks are detected but wormhole attack is doesn't detect. Because the wormhole attack is one of the harmful attacks which degrade the network performance. So, in the proposed system, one innovative technique is introduced which is called an efficient wormhole detection mechanism in the wireless sensor networks. In this method, considers the RTT between two successive nodes and those nodes' neighbor number which is needed to compare those values of other successive nodes. The identification of wormhole attacks is based on the two faces. The first consideration is t- at the transmission time between two wormhole attack affected nodes is considerable higher than that between two normal neighbor nodes. The second detection mechanism is based on the fact that by introducing new links into the network, the adversary increases the number of neighbors of the nodes within its radius. An experimental result shows that the proposed method achieves high network performance.

Identity Management 2015 |
The term identity management refers to the management of individual identities, their roles, authentication, authorizations, and privileges within or across systems. Examples include passwords, active directories, digital identities, tokens, and workflows. One of the core competencies for cybersecurity, the increasingly complex IT world demands smarter identity management solutions. The research cited here was presented in 2015.

Abstract: In the last few years, many organizations/users have adopted cloud storage systems. These storage systems provide a large virtual storage. When people move from web applications to cloud computing platform, their main concern point is how-to raise privacy of user’s sensitive data in cloud infrastructure. The traditional form of accessing cloud services is to use a username and password as a security token. During login/access time, new security risk may arise like virtualization attack, account/password sniffing, or phishing attack. Hence, cloud service provider (CSP) does not provide a complete security. Even though existing authentication scheme have addressed various security properties, there is still need of a secure authentication mechanism. This paper describes the need of claim-based identity management system, the basic terminology that is used in claim based approach and what is the advantage to use this approach. This paper proposes a model to extend the claim-based identity management scheme for cloud applications and provide a more secure way to access the cloud services. In this scheme, a new form of Security Assertion Markup Langauge (SAML) security tokens are created for identity, supported by Windows Communication Foundation (WCF) and hence, can prove more reliable with single interoperable approach to identify the works more secure in every situation in the cloud computing environment.

Abstract: Federated Identity Management (FIM), while solving important scalability, security and privacy problems of remote entity authentication, introduces new privacy risks. By virtue of sharing identities with many systems, the improved data quality of subjects may increase the possibilities of linking private data sets, moreover, new opportunities for user profiling are being introduced. However, FIM models to mitigate these risks have been proposed. In this paper we elaborate privacy by design requirements for this class of systems, transpose them into specific architectural requirements, and evaluate a number of FIM models with respect to these requirements. The contributions of this paper are a catalog of privacy-related architectural requirements, joining up legal, business and system architecture viewpoints, and the demonstration of concrete FIM models showing how the requirements can be implemented in practice.

Abstract: Ensuring identity management (IdM) systems availability plays a key role to support networked systems. Denial-of-Service (DoS) attacks can make IdM operations unavailable, preventing the use of computational resources by legitimate users. In the literature, the main countermeasures against DoS over IdM systems are based on either the application of external resources to extend the system lifetime (replication) or on DoS attacks detection. The first approach increases the solutions cost, and in general the second approach is still prone to high rates of false negatives and/or false positives. Hence, this work presents SAMOS, a novel and paradigm-shifting Scheme for DoS Attacks Mitigation by the reOrganization and optimization of the IdM System. SAMOS optimizes the reorganization of the IdM system components founded on optimization techniques, minimizing DoS effects and improving the system lifetime. SAMOS is based on the unavailabilities effects such as the exhaustion of processing and memory resources, eliminating the dependence of attacks detection. Furthermore, SAMOS employs operational IdPs from the IdM system to support the demand of the IdM system, differently from replication approaches. Results considering data from two real IdM systems indicate the scheme viability and improvements.

Abstract: The Cloud Computing is known for its high availability and low cost in implementation and maintenance. The Users of Cloud often give their secret credential for accessing application and/or data hosted on Cloud environment. Authentication is today’s one of the most challenging issues in the domain of security and privacy for the applications running under Cloud environment. As users’ access more than one service, sometimes using common credentials, User feels unsafe about disclosing their identity on the Cloud environment because their information may be used with other application/users to generate knowledge about their activities. In this paper, we propose a model which allows users to authenticate to the service securely and control the disclosure of their attributes. The proposed model offers users’ a flexibility to generate instant identity along with credential required to authenticate service provider. The instant identity for each service provider makes tough for them to track user’s access patterns. Due to rapid change in identity, service provider may not be able to locate user(s). The proposed model aims to assists the users to preserve privacy of their data.

Abstract: The Internet of Things (IoT) has been developing rapidly in the past few years. In IoT, an enormous number of smart devices are connected to the network, where communication and interaction occurs extensively among end users, smart devices and Internet services. Due to the great diversity of devices, broader scope of interactions and other characteristics of IoT, current IdM model for Internet needs to be extended and improved. The objective of this article is to analyze the main features of IoT and key issues of the IdM for IoT, and then present an IdM framework for IoT, which consists of three parts: the standard information model, user-centric architecture and multi-channel authentication.

Abstract: Many of the services on which we depend on the Internet where designed when communications security was not a major concern. The toll for retrofitted security was increased complexity. When search engines emerged users began to type only significant parts of a domain name into the search field and clicked on the appropriate link. In this poster we argue that this paradigm shift ultimately allows us to disentangle, replace and simplify the existing stack of Internet services related to name services and security.

Abstract: Nowadays, the combination between Cloud computing and Internet of Things (IoT) is pursuing new levels of efficiency in delivering services, representing a tempting business opportunity for ICT operators of increasing their revenues. However, security is seen as one of the major factors that slows down the rapid and large scale adoption and deployment of both the IoT and Cloud computing. In this paper, considering such an IoT Cloud scenario, we present an authentication model that allow IoT devices to join IoT Clouds and users to access the system. Moreover, we discuss the issues involved in applying our authentication models in a real IoT Cloud based on the FIWARE technology.

Abstract: Cloud computing allows the use of resources and systems in thousands of providers. This paradigm can use federated identity management to control user’s identification data, but it is essential to preserve privacy, while performing authentication and access control. This article discusses necessary characteristics to improve privacy in the dissemination of sensitive data of users in federated cloud computing paradigm. We plan to identify and use privacy techniques in identity management systems used in cloud. Users’ attributes should have associated policies to minimize release of data exchanged in the process. It is also necessary to deal with privacy in interactions between authentication and authorization processes. This paper presents an approach to address the issues involving privacy around the personally identifiable information. The proposed model allows control of users’ PII, provides some choices to assist users in data dissemination during the interaction and provides guarantees using user preferences on the SP side.

Abstract: Due to compliance and IT security requirements, company-wide Identity and Access Management within organizations has gained significant importance in research and practice over the last years. Companies aim at standardizing user management policies in order to reduce administrative overhead and strengthen IT security. Despite of its relevance, hardly any supportive means for the automated detection and refinement as well as management of policies are available. As a result, policies outdate over time, leading to security vulnerabilities and inefficiencies. Existing research mainly focuses on policy detection without providing the required guidance for policy management. This paper closes the existing gap by proposing a Dynamic Policy Management Process which structures the activities required for policy management in Identity and Access Management environments. In contrast to current approaches it fosters the consideration of contextual user management data for policy detection and refinement and offers result visualization techniques that foster human understanding. In order to underline its applicability, this paper provides a naturalistic evaluation based on real-life data from a large industrial company.

Abstract: Protocols for communication across security domains need to be evaluated against their architectural properties, not only their security properties. The protocols have connectivity and capacity requirements, they have implications on system coupling, scalability and management. This paper investigates several trust management mechanisms from the perspective of a list of non-functional requirements. The conclusions have consequences for the organization of Identity Management Systems used in cross-domain applications.

Abstract: In addressing the growing problem of security of Internet of Things, we present, from a statistical decision point of view, a naval approach for trust-based access control using Bayesian decision theory. We build a trust model, TrustBayes which represents a trust level for identity management in IoT. TrustBayes model is be applied to address access control on uncertainty environment where identities are not known in advance. The model consists of EX (Experience), KN (Knowledge) and RC (Recommendation) values which is be obtained in measurement while a IoT device requests to access a resource. A decision will be taken based model parameters and be computed using Bayesian decision rules. To evaluate our a trust model, we do a statistical analysis and simulate it using OMNeT++ to investigate battery usage. The simulation result shows that the Bayesian decision theory approach for trust based access control guarantees scalability and it is energy efficient as increasing number of devices and not affecting the functioning and performance.

Abstract: As cloud computing technology develops rapidly, more convenience has been brought to users by various cloud providers with various cloud services. However, difficulty of management, especially when different access control protocols and personal information involved, has become one of barriers that inhibit the development process of cloud technology. In this paper, a user-centered ID MaaS (Identity Management as a Service) is proposed combined with a novel access control model based on trust and risk evaluation. Besides, a format-preserving encryption (FPE) method is proposed as an auxiliary scheme guaranteeing the effectiveness of access control. ID MaaS offers a solution that effectively alleviates the difficulty of realizing unified management of users’ identity and information among diverse cloud service providers.

Abstract: This paper describes a fully-working proof of concept centered around a smart enterprise scenario and able to shed led on the power offered by linking the Internet of Things (IoT) and the Cloud Computing (CC) paradigms together. More specifically, in this showcase all the sensing and actuation capabilities are implemented in the tiny micro-controllers on-board the “things” and exposed, through a short-range radio module, as interfaces and commands, while all the smart capabilities (from identity management, to complex event processing, from data contextualization to persistent storage) are implemented as cloud services. In this way one can keep the computational and memory requirements of the devices extremely low, by off-loading the smartness of the application to the cloud services, where computational and memory resources are not an issue. Finally, to connect the two worlds together, a small linux embedded micro-pc is used as a controller, hence playing the role of a smart IoT gateway.

Abstract: Mobile and web applications increasingly leverage service-oriented architectures in which developers integrate third-party services into end user applications. This includes identity management, mapping and navigation, cloud storage, and advertising services, among others. While service reuse reduces development time, it introduces new privacy and security risks due to data repurposing and over-collection as data is shared among multiple parties who lack transparency into third-party data practices. To address this challenge, we propose new techniques based on Description Logic (DL) for modeling multiparty data flow requirements and verifying the purpose specification and collection and use limitation principles, which are prominent privacy properties found in international standards and guidelines. We evaluate our techniques in an empirical case study that examines the data practices of the Waze mobile application and three of their service providers: Facebook Login, Amazon Web Services (a cloud storage provider), and Flurry.com (a popular mobile analytics and advertising platform). The study results include detected conflicts and violations of the principles as well as two patterns for balancing privacy and data use flexibility in requirements specifications. Analysis of automation reasoning over the DL models show that reasoning over complex compositions of multi-party systems is feasible within exponential asymptotic timeframes proportional to the policy size, the number of expressed data, and orthogonal to the number of conflicts found.

Abstract: Cloud users are inevitably confronted with the potential risk of storing their crucial data into the remote data center of cloud service providers (CSP), which raises the concern among cloud users for their Identities and Trust for CSP’s. So their arises the need for an efficient identity and trust management system, which can serve to both CSP and Cloud Consumer and hence necessary to increase the service level agreements (SLA) between them. This paper propose a strong heterogeneous online and offline sign crypt model for a cloud network for the issue pertaining to identities and trust management. This model has certain merits: firstly, it set ups the secure, trustworthy connection between the cloud user and cloud data center, while maintaining the identities of the user and also it achieves confidentiality, authentication, and non-repudiation of services in a coherent single step. Secondly, it allows a cloud user in an Identity based cryptography (IBC) to send a request message to an internet host in public key infrastructure (PKI). Thirdly, it splits the generated sign crypt into two phases: a) Offline, and b) Online phase, and thereafter they are shown on several types of attacks. Our model is very suitable to provide high level of identity and trust management in cloud computing paradigm.

Abstract: Recent advances in information technology make remote collaboration and resource sharing easier for next generation of distributed systems. The Intercloud is an interconnection system of several cloud provider infrastructures that allows the dynamic coordination of the deployment of applications and the distribution of the load across multiple data centers. In this paper, we propose a new design to establish a new generation of secure collaborative cloud services where several companies are patially or fully pooling their resources to optimize their operating costs and increase the availability of their services in a secure way by performing secure access & authentication for collaborative interCloud exchange services.

Abstract: The Center for Strategic and International Studies estimates the annual cost from cyber crime to be more than $400 billion. Most notable is the recent digital identity thefts that compromised millions of accounts. These attacks emphasize the security problems of using clonable static information. One possible solution is the use of a physical device known as a Physically Unclonable Function (PUF). PUFs can be used to create encryption keys, generate random numbers, or authenticate devices. While the concept shows promise, current PUF implementations are inherently problematic: inconsistent behavior, expensive, susceptible to modeling attacks, and permanent. Therefore, we propose a new solution by which an unclonable, dynamic digital identity is created between two communication endpoints such as mobile devices. This Physically Unclonable Digital ID (PUDID) is created by injecting a data scrambling PUF device at the data origin point that corresponds to a unique and matching descrambler/hardware authentication at the receiving end. This device is designed using macroscopic, intentional anomalies, making them inexpensive to produce. PUDID is resistant to cryptanalysis due to the separation of the challenge response pair and a series of hash functions. PUDID is also unique in that by combining the PUF device identity with a dynamic human identity, we can create true two-factor authentication. We also propose an alternative solution that eliminates the need for a PUF mechanism altogether by combining tamper resistant capabilities with a series of hash functions. This tamper resistant device, referred to as a Quasi-PUDID (Q-PUDID), modifies input data, using a black-box mechanism, in an unpredictable way. By mimicking PUF attributes, Q-PUDID is able to avoid traditional PUF challenges thereby providing high-performing physical identity assurance with or without a low performing PUF mechanism. Three different application scenarios with mobile devices for PUDID and Q-PUDID have been analyzed to show their unique advantages over traditional PUFs and outline the potential for placement in a host of applications.

Abstract: Evolutions of communications and the advent of Web real time technologies are further challenging the Telco ecosystem. New architectures are emerging to enable new services in a context where assets as identity, signaling and network management are decoupled and virtually delaminated, so to speak. This paper tackles three challenges to face to enable Telco to embrace these evolutions. First we need a secure, trustful and privacy-friendly way of using services provided by various identity and communication providers. Second, we need a versatile framework to develop and deploy communication services. The third challenge is to overcome the limitation of best effort networking by enabling specialized network services for de-perimeterized service delivery.

Abstract: This paper describes scenarios and services based on Federated Identity technology. The authors emphasize the Single Sign On mechanism, in which a user’s single authentication credential is used to log in once without being prompted to authenticate again to other systems. The overview of Federated Identity and a Federated Identity Management System is presented first. Next, federation approaches used in different fields of human activity are discussed. A few examples of such domains are presented: E-health, E-government, E-learning, and E-business. Also, two different use cases were proposed: a federated approach for tourism which provide a better service for customers, and in the health care sector, which improves medical service quality and reduces treatment costs. The last section describes the prototype which was implemented and tested in network environment.

Immersion systems, commonly known as “virtual reality”, are used for a variety of functions such as gaming, rehabilitation, and training. These systems mix the virtual with the actual, and have implications for cybersecurity because attackers may make the jump from virtual to actual systems. For the Science of Security community, this work is relevant to resilience, human factors, cyber physical systems, privacy, and composability. Work cited here was presented in 2015.

Abstract: The use of 3-D immersive Virtual World Learning Environments (VWLE) for educational purposes has been rapidly increased in the last few decades. Recent studies focusing on the evaluation of such environments have shown the great potential of virtual worlds in e-learning, providing improvement in factors such as satisfaction, enjoyment, concentration and presence compared to traditional educational practices. In this paper we present the 3D VWLE that has been developed at the framework of the V-ALERT project; the system's main goal is to contribute to the improvement of Information Security(IS) issues awareness. In particular, we present the methodology followed to evaluate critical aspects of the implemented platform, such as usability, presence and educational value. The data analysis has shown that the implemented system is usable, offered to the users high presence perception and increased their knowledge regarding IS.

Abstract: The use of a collaborative virtual reality environment for training and virtual tours has been increasingly recognized an as alternative to traditional reallife tours for university campuses. Our proposed application shows an immersive collaborative virtual reality environment for performing virtual online campus tours and evacuation drills using Oculus Rift head mounted displays. The immersive collaborative virtual reality environment also offers a unique way for training in emergencies for campus safety. The participant can enter the collaborative virtual reality environment setup on the cloud and participate in the evacuation drill or a tour which leads to considerable cost advantages over large scale real life exercises. This paper presents an experimental design approach to gather data on human behavior and emergency response in a university campus environment among a set of players in an immersive virtual reality environment. We present three ways for controlling crowd behavior: by defining rules for computer simulated agents, by providing controls to the users to navigate in the VR environment as autonomous agents, and by providing controls to the users with a keyboard/ joystick along with an immersive VR head set in real time. Our contribution lies in our approach to combine these three methods of behavior in order to perform virtual evacuation drills and virtual tours in a multi-user virtual reality environment for a university campus. Results from this study can be used to measure the effectiveness of current safety, security, and evacuation procedure for campus safety.

Abstract: This document introduces a new application for rendering massive LiDAR point cloud data sets of interior environments within high resolution immersive VR display systems. Overall contributions are: to create an application which is able to visualize large-scale point clouds at interactive rates in immersive display environments, to develop a flexible pipeline for processing LiDAR data sets that allows display of both minimally processed and more rigorously processed point clouds, and to provide visualization mechanisms that produce accurate rendering of interior environments to better understand physical aspects of interior spaces. The work introduces three problems with producing accurate immersive rendering of Li-DAR point cloud data sets of interiors and presents solutions to these problems. Rendering performance is compared between the developed application and a previous immersive LiDAR viewer.

Abstract: In this paper we compare participants' behavior and experience when navigating through a virtual environment populated with virtual agents in an IVR (Immersive Virtual Reality) system and a semi-IVR system. We measured the impact of collision and basic interaction between participants and virtual agents in both systems. Our findings show that it is more important for our semi-IVR systems to facilitate collision avoidance between the user and the virtual agents accompanied with basic interaction between them. This can increase the sense of presence and make the virtual agents and the environment appear more realistic and lifelike.

Abstract: This paper proposes a big-span position tracking algorithm based on pre-position time series to determine the user operation intention in virtual environment. Some problems, such as lost subject and inconvenient operation, when a tracker is working on big-scale models, like an airplane or a ship, can't be solved well in an immersive virtual reality system. Based on the moving trajectory and speed of a tracker in a unit of time span, the tracking algorithm is a plus to the mainstream relative position algorithm. The algorithm can tell the magnitude and intensity of a user's operation. It makes it especially convenient to display large-scale models in the CAVE system. Cases are used in this thesis to prove the effectiveness and convenience of this algorithm.

Abstract: We present the results of a variable information space experiment, targeted at exploring the scalability limits of immersive high resolution, tiled-display walls under physical navigation. Our work is motivated by a lack of evidence supporting the extension of previously established benefits on substantially large, room-shaped displays. Using the Reality Deck, a gigapixel resolution immersive display, as its apparatus, our study spans four display form-factors, starting at 100 megapixels arranged planarly and up to one gi-gapixel in a horizontally immersive setting. We focus on four core tasks: visual search, attribute search, comparisons and pattern finding. We present a quantitative analysis of per-task user performance across the various display conditions. Our results demonstrate improvements in user performance as the display form-factor changes to 600 megapixels. At the 600 megapixel to 1 gigapixel transition, we observe no tangible performance improvements and the visual search task regressed substantially. Additionally, our analysis of subjective mental effort questionnaire responses indicates that subjective user effort grows as the display size increases, validating previous studies on smaller displays. Our analysis of the participants' physical navigation during the study sessions shows an increase in user movement as the display grew. Finally, by visualizing the participants' movement within the display apparatus space, we discover two main approaches (termed “overview” and “detail”) through which users chose to tackle the various data exploration tasks. The results of our study can inform the design of immersive high-resolution display systems and provide insight into how users navigate within these room-sized visualization spaces.

Abstract: Immersive simulation is a staple of training for many complex system operators, including astronauts and ground operators of spacecraft. However, while much has been written about simulators, simulation facilities, and operator certification programs, the topic of how one develops simulation scenarios to train a spacecraft operator is relatively understated in the literature. In this paper, an approach is presented for using control theory as the basis for developing the immersive simulation scenarios for a spacecraft operator training program. The operator is effectively modeled as a high level controller of lower level hardware and software control loops that affect a select set of system state variables. Simulation scenarios are derived from a STAMP-based hazard analysis of the operator's high and low level control loops. The immersive simulation aspect of the overall training program is characterized by selecting a set of scenarios that expose the operator to the various inadequate control actions that stem from control flaws and inadequate control executions in the different sections of the typical control loop. Results from the application of this approach to the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission are provided through an analysis of the simulation scenarios used for operator training and the actual anomalies that occurred during the mission. The simulation scenarios and inflight anomalies are mapped to specific control flaws and inadequate control executions in the different sections of the typical control loop to illustrate the characteristics of anomalies arising from the different sections of the typical control loop (and why it is important for operators to have exposure to these characteristics). Additionally, similarities between the simulation scenarios and inflight anomalies are highlighted to make the case that the simulation scenarios prepared the operators for the mission.

Abstract: To ensure safety and usability of advanced in-car cockpit solutions, prospective evaluation during early prototyping stages is important, especially when developing innovative human-cockpit-interactions. In this context, highly realistic test environments will help to provide reliable and valid findings. Nevertheless, real car driving studies are difficult to control, manipulate, replicate and standardize. They are also more time consuming and expensive. One economizing suggestion is the implementation of immersive driving environments within simulator studies to provide users with a more realistic awareness of the situation. This paper discusses research investigating the influence of immersive driving environments. We evaluated three interaction modalities (touch, spin controller, free-hand gestures), and two levels of immersivity (low, high) to examine this methodology. Twenty participants took part in the driving simulator study. Objective and subjective data show advantages regarding situational awareness and perception for high immersive driving environments when interacting with a navigation system.

Abstract: Human sensory systems allow individuals to see, hear, touch, and interact with the surrounding physical environment. Understanding human perception and its limit enables us to better exploit the psychophysics of human perceptual systems to design more efficient, adaptive algorithms and develop perceptually-inspired computational models. In this talk, I will survey some of recent efforts on perceptually-inspired computing with applications to crowd simulation and multimodal interaction. In particular, I will present data-driven personality modeling based on the results of user studies, example-guided physics-based sound synthesis using auditory perception, as well as perceptually-inspired simplification for multimodal interaction. These perceptually guided principles can be used to accelerating multi-modal interaction and visual computing, thereby creating more natural human-computer interaction and providing more immersive experiences. I will also present their use in interactive applications for entertainment, such as video games, computer animation, and shared social experience. I will conclude by discussing possible future research directions.

Abstract: Space exploration missions have produced large data of immense value, to both research and the planning and operating of future missions. However, current datasets and simulation tools fragment teamwork, especially across disciplines and geographical location. The aerospace community already exploits virtual reality for purposes including space tele-robotics, interactive 3D visualization, simulation and training. However, collaborative virtual environments are yet to be widely deployed or routinely used in space projects. Advanced immersive and collaborative visualization systems have the potential for enhancing the efficiency and efficacy of data analysis, simplifying visual benchmarking, presentations and discussions. We present preliminary results of the EU funded international project CROSS DRIVE, which develops an infrastructure for collaborative workspaces for space science and missions. The aim is to allow remote scientific and engineering experts to collectively analyze and interpret combined datasets using shared simulation tools. The approach is to combine advanced 3D visualization techniques and interactive tools in conjunction with immersive virtuality telepresence. This will give scientists and engineers the impression of teleportation from their respective buildings across Europe, to stand together on a planetary surface, surrounded by the information and tools that they need. The conceptual architecture and proposed realization of the collaborative workspace are described. ESA's planned ExoMars mission provides the use-case for deriving user requirements and evaluating our implementation.

Abstract: Learning games are becoming a serious contender to real-life simulations for professional training, particularly in highly technical jobs where their cost-effectiveness is a sizeable asset. The most appreciated feature of a learning game is to provide in an automatic way to each learner an integrated feedback in real time during the game and, ideally, a personally meaningful debriefing at the end of each session. Immersive learning games use virtual reality and 3D environments to allow several learners at once to collaborate in the most natural way. Managing the communication on the other hand has proven so far a more difficult problem to overcome. In this article, we present a communication system designed to be used in immersive learning games. This innovative system is neither based on voice-chat nor branching dialogues but on the idea that pieces of information can be manipulated as tangible objects in a virtual environment. This system endeavours to offer the simplest and most intuitive way for several learners to acquire and share knowledge in an immersive virtual environment while complying with the requirements of a reliable assessment of their performance. A first experiment with nurse anaesthetist students gives evidence that this simple communication system is apt to support lifelike behaviours such as consultation, debate, conflict or irritation.

Abstract: The use of perceptual inputs is an emerging area within HCI that suggests a developing Perceptual User Interface (PUI) that may prove advantageous for those involved in mobile serious games and immersive social network environments. Since there are a large variety of input devices, software platforms, possible interactions, and myriad ways to combine all of the above elements in pursuit of a PUI, we propose in this paper a basic experimental framework that will be able to standardize study of the wide range of interactive applications for testing efficacy in learning or information retrieval and also suggest improvements to emerging PUI by enabling quick iteration. This rapid iteration will start to define a targeted range of interactions that will be intuitive and comfortable as perceptual inputs, and enhance learning and information retention in comparison to traditional GUI systems. The work focuses on the planning of the technical development of two scenarios.

Abstract: This paper presents an immersive virtual reality system that includes a natural interaction approach based on free hand gestures that is used to drive a Desktop Haptic Strip for Shape Rendering (DHSSR). The DHSSR is a mechatronic display of virtual curves intersecting 3D virtual objects, and aims at allowing designers to evaluate the quality of shapes during the conceptual design phase of new products. The DHSSR consists of a 6DOF servo-actuated developable metallic strip, which reproduces cross-sectional curves of 3D virtual objects. Virtual curves can be interactively generated on the 3D surface of the virtual object, and coherently the DHSSR haptic interface renders them. An intuitive and natural modality for interacting with the 3D virtual objects and 3D curves is offered to users, who are mainly industrial designers. This consists of an immersive virtual reality system for the visualization of the 3D virtual models and a hand gestural interaction approach used by the user for handling the models. The system has been implemented by using low cost and open technologies, and combines a software engine for interactive 3D content generation (Unity 3D), the Oculus Rift Head Mounted Display for 3D stereo visualization, a motion capture sensor (LeapMotion) for tracking the user's hands, and the Arduino Leonardo board for controlling the components. Results reported in the paper are positive for what concerns the quality of the rendering of the surface, and of the interaction modality proposed.

Abstract: In this paper, we present an innovative approach to design a gaze-controlled Multimedia User Interface for modern, immersive headsets. The wide-spread availability of consumer grade Virtual Reality Head Mounted Displays such as the Oculus RiftTM transformed VR to a commodity available for everyday use. However, Virtual Environments require new paradigms of User Interfaces, since standard 2D interfaces are designed to be viewed from a static vantage point only, e.g. the computer screen. Additionally, traditional input methods such as the keyboard and mouse are hard to manipulate when the user wears a Head Mounted Display. We present a 3D Multimedia User Interface based on eye-tracking and develop six applications which cover commonly operated actions of everyday computing such as mail composing and multimedia viewing. We perform a user study to evaluate our system by acquiring both quantitative and qualitative data. The study indicated that users make less type errors while operating the eye-controlled interface compared to using the standard keyboard during immersive viewing. Subjects stated that they enjoyed the eye-tracking 3D interface more than the keyboard/mouse combination.

Abstract: BlenderVR is an open-source project framework for interactive and immersive applications based on an extension of the Blender Game Engine to Virtual Reality applications. BlenderVR is a generalization of the BlenderCAVE project, accounting for alternate platforms (e.g., HMD, video-walls). The goal is to provide a flexible and easy to use framework for the creation of VR applications for various platforms, making use of the existing power of the BGE's graphics rendering and physics engine. Compatible with 3 major Operating Systems, BlenderVR has been developed by VR researchers with support from the Blender Community. BlenderVR currently handles multi-screen/multi-user tracked stereoscopic rendering through efficient low-level master/slave synchronization process with multimodal interactions via OSC and VRPN protocols.

Abstract: We introduce a method for using multiple devices as windows for interacting with 3-D virtual environment. Motivation of our work has come from generating collaborative workspace with multiple devices which can be found in our daily lives, like desktop PC and mobile devices. Provided with life size virtual environment, each device shows a scene of 3-D virtual space on its position and direction, and users would be able to perceive virtual space in more immersive way with it. By adopting mobile device to our system, users not only see outer space of stationary screen by relocating their mobile device, but also have personalized view in working space. To acquiring knowledge of device's pose and orientation, we adopt vision-based approaches. For the last, we introduce an implementation of a system for managing multiple device and letting them have synchronized performance.

Abstract: Robots which solve complex tasks in environments too dangerous for humans to enter are desperately needed, e.g. for search and rescue applications. As fully autonomous robots are not yet capable of operating in highly unstructured real-world scenarios, teleoperation is often used to embed the cognitive capabilities of human operators into the robotic system. The many degrees of freedom of anthropomorphic robots and communication restrictions pose challenges to the design of teleoperation interfaces, though. In this work, we propose to combine immersive 3D visualization and tracking of operator head and hand motions to an intuitive interface for bimanual teleoperation. 3D point clouds acquired from the robot are visualized together with a 3D robot model and camera images using a tracked 3D head-mounted display. 6D magnetic trackers capture the operator hand motions which are mapped to the grippers of our two-armed robot Momaro. The proposed user interface allows for solving complex manipulation tasks over degraded communication links, as demonstrated at the DARPA Robotics Challenge Finals and in lab experiments.

Abstract: In recent years, due to deteriorating global warming, there has been increasing attention to home energy savings, which is often a serious and not so interesting task. In this regard, we proposed a playful and bidirectionally interactive eco-feedback with three kinds of information visualization integrated with a 3D pet-raising game, which synchronously visualizes the information of the physical environment with the virtual environment by leveraging IoT (Internet of Things) enabled technologies in hopes of enhancing user experience and prolonging users' engagement in energy savings. In addition to mere mapping from physical to virtual environment for traditional game-based energy savings, this study also makes use of the other direction to form a bidirectional mapping to empower users to allow direct and flexible remote control anywhere and anytime in a more natural and playful way. Furthermore, integrating context-awareness with the bidirectional mapping in an energy-saving system also enhances the immersive experience of the users.

Information Theoretic Security 2015 |
A cryptosystem is said to be information-theoretically secure if its security derives purely from information theory and cannot be broken even when the adversary has unlimited computing power. For example, the one-time pad is an information-theoretically secure cryptosystem proven by Claude Shannon, inventor of information theory, to be secure. Information-theoretically secure cryptosystems are often used for the most sensitive communications such as diplomatic cables and high-level military communications, because of the great efforts enemy governments expend toward breaking them. Because of this importance, methods, theory and practice in information theory security also remains high. The works cited here was presented in 2015.

Abstract: The past decade has witnessed significant effort towards establishing reliable and information theoretically secure rates in communication networks, taking advantage of the properties of the communication medium. Such efforts include those in the wireless medium where simultaneous transmissions and the ensuing interference can prove advantageous from an information theoretic secrecy point of view. With the goal of obtaining a secrecy rate that scales with transmit power, structured signaling with simultaneous favorable signal alignment at the legitimate receiver(s) and unfavorable signal alignment at the eavesdropper(s) has proven particularly useful in multi-terminal Gaussian channels. Many challenges remain however in realizing the vision of absolute security provided by the wireless physical layer including handling more realistic models. In this paper, we provide a brief overview of the state of the art, the forward look and argue for an additional asset that could be utilized for secrecy, i.e., bidirectional signaling. Taking the bidirectional wiretap channel as an example, Gaussian signaling is demonstrated to be as good as structured signaling from the degrees of freedom point of view, while observed to be performing better with finite transmit power. Moreover, taking bidirectional signals explicitly into account for encoding performs even better and provides a way forward to synergistically combine physical layer based secrecy and encryption.

Abstract: This paper considers the problem of communication over a discrete memoryless channel subject to the constraint that the probability that an adversary who observes the channel outputs can detect the communication is low. Specifically, the relative entropy between the output distributions when a codeword is transmitted and when no input is provided to the channel must be sufficiently small. For a channel whose output distribution induced by the zero input symbol is not a mixture of the output distributions induced by other input symbols, it is shown that the maximum number of bits that can be transmitted under this criterion scales like the square root of the blocklength. Exact expressions for the scaling constant are also derived.

Abstract: We study the problem of constructing secure regenerating codes that protect data integrity in distributed storage systems (DSS) in which some nodes may be compromised by a malicious adversary. The adversary can corrupt the data stored on and transmitted by the nodes under its control. The “damage” incurred by the actions of the adversary depends on how much information it knows about the data in the whole DSS. We focus on the limited-knowledge model in which the adversary knows only the data on the nodes under its control. The only secure capacity-achieving codes known in the literature for this model are for the bandwidth-limited regime and repair degree d = n-1, i.e., when a node fails in a DSS with n nodes all the remaining n - 1 nodes are contacted for repair. We extend these results to the more general case of d ≤ n - 1 in the bandwidth-limited regime. Our capacity-achieving scheme is based on the use of product-matrix codes with special hashing functions and allow the identification of the compromised nodes and their elimination from the DSS while preserving the data integrity.

Abstract: Fail-stop signatures (FSS) provide the security for a signer against a computationally unbounded adversary by enabling the signer to provide a proof of forgery. Conventional FSS schemes are for a single-signer setting, but in the real world, there is a case where a countersignature of multiple signers (e.g. A signature between a bank, a user, and a consumer) is required. In this work, we propose a framework of FSS capturing a multi-signer setting and call the primitive fail-stop multisignatures (FSMS). We propose a generic construction of FSMS via the bundling homomorphisms proposed by Pfitzmann and then propose a provably secure instantiation of the FSMS scheme from the factoring assumption. Our proposed schemes can be also extended to fail-stop aggregate signatures (FSAS).

Abstract: The authentication error in Two-Hop wireless networks is considered without knowledge of eavesdropper channels and location. This paper presents an eavesdropper model with authentication error and two eavesdropping ways. In the model, the authentication error is expressed a pair (p_1, p_2). Based on the authentication error, a cooperative transmission protocol against impersonation attack is presented. Then, the number of eavesdroppers can be tolerated is analyzed while the desired secrecy is achieved with high probability in the limit of a large number of relay nodes. Final, we draw two conclusions for authentication error: 1) the impersonate nodes are chosen as relay is the dominant factor of the transmitted message leakage, and the impersonation attack does seriously decrease the number of eavesdroppers can be tolerated. 2) The Error authentication to legitimate nodes is almost no effect on the number of eavesdroppers can be tolerated.

Abstract: Information-theoretic security through linear network coding (LNC) is achievable only when a limited number of network links with linearly-independent global coding vectors are attacked, while security is not guaranteed otherwise. We incorporate LNC-based security and asymmetric-key cryptography to provide data protection in more realistic cases where the wiretapper attacks an arbitrary number of links. Therefore, LNC-based security protects network irrespective of the computing power of the adversary when the number of attacked links falls below a certain amount r, whereas computational security enters into the scene to protect data against computationally-bounded attackers capable of tapping any number of links.

Abstract: This paper considers optimal multi-carrier (multiple messages) spread-spectrum (SS) data embedding on linearly-transformed host. We present information-theoretic security analysis for the optimal SS embedding. The security is quantified by both the Kullback-Leibler distance and Bhattacharyya distance between the cover and stego probability distributions. The main results of this paper permit to establish fundamental security limits for the optimal SS embedding. Theoretical analysis and experimental results show the impact of the number of embedding messages, the embedding distortion, and the host transformation in the security level.

Abstract: Truthful auctions make bidders reveal their true valuations for goods to maximize their utilities. Currently, almost all spectrum auction designs are required to be truthful. However, disclosure of one's true value causes numerous security vulnerabilities. Secure spectrum auctions are thus called for to address such information leakage. Previous secure auctions either did not achieve enough security, or were very slow due to heavy computation and communication overhead. In this paper, inspired by the idea of secret sharing, we design an information-theoretically secure framework (ITSEC) for truthful spectrum auctions. As a distinguished feature, ITSEC not only achieves information-theoretic security for spectrum auction protocols in the sense of cryptography, but also greatly reduces both computation and communication overhead by ensuring security without using any encryption/description algorithm. To our knowledge, ITSEC is the first information-theoretically secure framework for truthful spectrum auctions in the presence of semi-honest adversaries. We also design and implement circuits for both single-sided and double spectrum auctions under the ITSEC framework. Extensive experimental results demonstrate that ITSEC achieves comparable performance in terms of computation with respect to spectrum auction mechanisms without any security measure, and incurs only limited communication overhead.

Abstract: Nowadays take place active development and approbation of new methodologies and algorithms for solving the problem of complex development of the protected telecommunication systems, security assessment and information security management. A lot of works describe mathematical and theoretic security models. There is no universal security model of telecommunication system that allows to effectively combine the requirements of normatively-methodical documents, threats' model and attackers' profile on the stage of planning, allows to generate the list of protective measures and allows to find the optimal set of information security tools. Normatively-methodical documents analysis shows that there is no universal approach for development of the protected telecommunication systems, threats' model and attackers' profile creation. Described in the article threats' model creation methodology allows to effectively solve problem of particular threats' model creation. The attackers' profile creation algorithm allows to uniquely classify attacker's and to create actual threats' list according to attacker's level's of impact to telecommunication system. Both models are the basis of telecommunication systems' security model. This article describes algorithm of telecommunication systems' security model creation, basic requirements for protected telecommunication systems and main stages of development of the protected telecommunication systems.

Abstract: Advancements in information technology has increased the use of internet. With the pervasiveness of internet, network security has become critical issue in every organization. Network attacks results in massive amount of loss in terms of money, reputation and data confidentiality. Reducing or eliminating the negative effects of any intrusion is a fundamental issue of network security. The network security problem can be represented as a game between the attacker or intruder and the network administrator where both the players try to attain maximum outcome. The network administrator tries to defend the attack and the attacker tries to overcome it and attack the system. Thus network security can be enforced using game theoretic approach. This paper presents a review of game theoretic solutions developed for network security.

Abstract: Wireless networks are subject to security vulnerability due to the broadcasting nature of radio transmission. Information-theoretic approaches for secure communication propose to generate secret keys from a common source, such as reciprocal channels, available to the transmitter and receiver. However, such approaches assume the probability distribution of the sources, which may not be available in many realistic scenarios. In this paper, we establish an information-theoretic framework for secret-key generation (SKG) using noisy observations of unknown deterministic parameters (UDPs). Based on an axiomatic definition of UDPs, we derive a new metric called intrinsic information between the UDP and its observation, characterizing the rate of the secret key that can be generated from the observation. This metric is then applied to quantify the use of wideband channels in mobile networks for SKG. Our results provide a non-Bayesian perspective for SKG as well as its practical implications.

Abstract: Preserving the privacy of private communication is a fundamental concern of computing addressed by encryption. Information-theoretic reasoning models unconditional security where the strength of the results is not moderated by computational hardness or unproven results. Perfect secrecy is often considered the ideal result for a cryptosystem, where knowledge of the ciphertext reveals no information about the key or message, however often this is impossible to achieve in practice. An alternative measure is the equivocation, intuitively the average number of message/key pairs that could have produced a given ciphertext. We show a theoretical bound on equivocation called max equivocation and show that this generalizes perfect secrecy when achievable, and provides an alternative measure when perfect secrecy is not. We derive bounds for max-equivocation, and show that counter intuitively max-equivocation is achieved when the entropy of the ciphertext is minimized. We consider encryption functions under this new information, and show that in general the theoretical best is unachievable, and that some popular approaches such as Latin squares or Quasigroups are also not optimal. We present some algorithms for generating encryption functions that are practical and achieve 90-95% of the theoretical best, improving with larger message spaces.

Abstract: In wireless communication, spectrum resources are utilized by authorities in particular fields. Most of the elements in spectrum are idle. Cognitive radio is a promising technique for allocating the idle spectrum into unlicensed users. Security shortage is a major challenging issue in cognitive radio ad-hoc networks (CRAHNs) that makes performance degradation on spectrum sensing and sharing. A selfish user pre-occupies the accessible bandwidth for their prospect usage and prohibits the progress secondary users whose makes the requirement for spectrum utility. Game theoretic model is proposed to detect the selfish attacker in CRAHNs. Channel state information (CSI) is considered to inform each user's channel handing information. The two strategy of Nash Equilibrium game model such as pure and mixed strategy for secondary users (SUs) and selfish secondary users (SSUs) are investigated and the selfish attacker is detected. Moreover a novel belief updating system is also proposed to the secondary users for knowing the CSI of the primary user. A simulation result shows that, game theoretic model is achieved to increase the detection rate of selfish attackers.

Abstract: In the recent years, a set of works have addressed inherent characteristics of the fading propagation channel in an information-theoretic framework oriented towards security. In particular, for cryptographic purposes, secure key bits can be extracted from reciprocal radio channels, seen as a shared source of randomness between any two entities. In this paper we intend to assess the impact of true radio channel features on the security performance, by quantizing the complex channel coefficients into discrete key bits. To this end, indoor channel measurements were performed and investigated in different scenarios, e.g. LOS/NLOS condition, narrowband (NB) as well as wide band (WB) targeting OFDM systems. Secret key robustness is firstly studied for the legitimate terminals in terms of key bit disagreement ratio and key randomness, and secondly by considering an eavesdropper in a wide set of positions around these terminals and by evaluating the difference between the generated keys. A simplified channel model is also analyzed in comparison with the measured channels, as regards the characteristics of generated key bits.

Abstract: A model of an encryption approach is analyzed from an information-theoretic point of view. In the model, an attacker faces the problem of observing messages through a concatenation of a binary symmetric channel and a channel with randomly inserted bits. The paper points out to a number of security related implications resulting from employing an insertion channel. It is shown that deliberate and secret-key-controlled insertions of random bits into the basic ciphertext provide a security enhancement of the resulting encryption scheme.

Abstract: We consider Gaussian-channel networks that employ lattice-based physical-layer network coding (PNC) as their routing strategy. Under the assumption that the communication is subject to the adversarial attacks in the form of wiretapping, we address data security from an information-theoretic viewpoint. To this end, we first examine how data transfer in PNC-based networking is vulnerable against wiretapping attacks, and then we show that it, due to the structured codebook employed in PNC, is possible to apply the already available lattice coset coding to obstruct the attackers in obtaining any information from the data communicated over the network. Several wiretap attack scenarios targeted to such networks are considered and possible solutions are discussed.

Abstract: This work proposes a novel metric to characterize the resilience of stochastic cyber-physical systems to attacks and faults. We consider a single-input single-output plant regulated by a control law based on the estimate of a Kalman filter. We allow for the presence of an attacker able to hijack and replace the control signal. The objective of the attacker is to maximize the estimation error of the Kalman filter - which in turn quantifies the degradation of the control performance - by tampering with the control input, while remaining undetected. We introduce a notion of ε-stealthiness to quantify the difficulty to detect an attack when an arbitrary detection algorithm is implemented by the controller. For a desired value of ε-stealthiness, we quantify the largest estimation error that an attacker can induce, and we analytically characterize an optimal attack strategy. Because our bounds are independent of the detection mechanism implemented by the controller, our information-theoretic analysis characterizes fundamental security limitations of stochastic cyber-physical systems.

Abstract: This paper addresses the issue of detecting changes in stochastic processes. In conventional studies on change detection, it has been explored how to detect discrete changes for which the statistical models of data suddenly change. We are rather concerned with how to detect continuous changes which occurs incrementally over some successive periods. This paper gives a novel methodology for detecting continuous changes. We first define the information-theoretic measure of continuous change and prove that it is invariant with respect to the parametrization of statistical model. We then propose an efficient algorithm to detect continuous changes according to the proposed measure. We demonstrate the effectiveness of our method through the experiments using synthetic data and the applications to security and economic event detection.

Abstract: Privacy is a critical issue when communicating over shared mediums. A fundamental model for the information-theoretic analysis of secure communications is the wiretap channel (WTC), which consists of a communicating pair and an eavesdropper. In this work we study the secrecy capacity of Gaussian multiple-input multiple-output (MIMO) WTCs with finite memory. These channels are very common in wireless communications as well as in wireline communications (e.g., in power line communications). We derive a closed-form expression for the secrecy capacity of the MIMO Gaussian WTC with finite memory via the analysis of an equivalent block-memoryless model, which is transformed into a set of parallel independent memoryless MIMO WTCs. The secrecy capacity is expressed as the maximization over the input covariance matrices in the frequency domain. Finally, we show that for the Gaussian scalar WTC with finite memory, the secrecy capacity can be obtained by waterfilling.

Abstract: We consider the problem of computation in a cloud environment where either the data or the computation may be corrupted by an adversary. We assume that a small fraction of the data is stored locally at a client during the upload process to the cloud and that this data is trustworthy. We formulate the problem within a game theoretic framework where the client needs to decide an optimal fusion strategy using both non-trusted information from the cloud and local trusted data, given that the adversary on the cloud is trying to deceive the client by biasing the output to a different value/set of values. We adopt an Iterated Best Response (IBR) scheme for each player to update its action based on the opponent's announced computation. At each iteration, the cloud reveals its output to the client, who then computes the best response as a linear combination of its private local estimate and of the untrusted cloud output. We characterize equilibrium conditions for both the scalar and vector cases of the computed value of interest. Necessary and sufficient conditions for convergence for the IBR are derived and insightful geometric interpretations of such conditions is discussed for the vector case. Numerical results are presented showing the convergence conditions are relatively tight.

Abstract: Spatial modulation (SM) and space shift keying (SSK) represent transmission methods for low-complexity implementation of multiple-input multiple-output (MIMO) wireless systems in which antenna indices are employed for data transmission. In this paper, we focus our attention on the secrecy behavior of SSK and SM. Using an information-theoretic framework, we derive expressions for the mutual information and consequently compute achievable secrecy rates for SSK and SM via numerical evaluations. We also characterize the secrecy behavior of SSK by showing the effects of increasing the number of antennas at the transmitter as well as the number of antennas at the legitimate receiver and the eavesdropper. We further evaluate the secrecy rates achieved by SM with different sizes of the underlying signal constellation and compare the secrecy performance of this scheme with those of general MIMO and SIMO systems. The proposed framework unveils that SM is capable of achieving higher secrecy rates than the conventional single-antenna transmission schemes. However, it underperfoms compared to a general MIMO system in terms of the achievable secrecy rates.

Abstract: Cybersecurity is among the highest priorities in industries, academia and governments. Cyber-threats information sharing among different organizations has the potential to maximize vulnerabilities discovery at a minimum cost. Cyber-threats information sharing has several advantages. First, it diminishes the chance that an attacker exploits the same vulnerability to launch multiple attacks in different organizations. Second, it reduces the likelihood an attacker can compromise an organization and collect data that will help him launch an attack on other organizations. Cyberspace has numerous interconnections and critical infrastructure owners are dependent on each other's service. This well-known problem of cyber interdependency is aggravated in a public cloud computing platform. The collaborative effort of organizations in developing a countermeasure for a cyber-breach reduces each firm's cost of investment in cyber defense. Despite its multiple advantages, there are costs and risks associated with cyber-threats information sharing. When a firm shares its vulnerabilities with others there is a risk that these vulnerabilities are leaked to the public (or to attackers) resulting in loss of reputation, market share and revenue. Therefore, in this strategic environment the firms committed to share cyber-threats information might not truthfully share information due to their own self-interests. Moreover, some firms acting selfishly may rationally limit their cybersecurity investment and rely on information shared by others to protect themselves. This can result in under investment in cybersecurity if all participants adopt the same strategy. This paper will use game theory to investigate when multiple self-interested firms can invest in vulnerability discovery and share their cyber-threat information. We will apply our algorithm to a public cloud computing platform as one of the fastest growing segments of the cyberspace.

Abstract: We consider reliable and secure communication of information over a multipath network. A transmitter Alice sends messages to the receiver Bob in the presence of a hidden adversary Calvin. The adversary Calvin can both eavesdrop and jam on (possibly non-identical) subsets of transmission links. The goal is to communicate reliably (intended receiver can understand the messages) and secretly (adversary cannot understand the messages). Two kinds of jamming, additive and overwrite, are considered. Additive jamming corresponds to wireless network model while overwrite jamming corresponds to wired network model and storage systems. The multipath network consists of C parallel links. Calvin can both jam and eavesdrop any zio number of links, can eavesdrop (but not jam) any zi/o number of links, and can jam (but not eavesdrop) any zo/i number of links. We present the first “complete” information-theoretic characterization of maximum achievable rate as a function of the number of links that can be jammed and/or eavesdropped for equal and unequal link capacity multipath networks under additive and overwrite jamming in the large alphabet regime. Our achievability and converse proofs require non-trivial combination of information theoretic and coding theoretic ideas and our achievability schemes are computationally efficient. The PHaSE-Saving techniques1 are used for achievability while a “stochastic” singleton bound is obtained for converse.

Abstract: In the Internet-of-Things (IoT), users might share part of their data with different IoT prosumers, which offer applications or services. Within this open environment, the existence of an adversary introduces security risks. These can be related, for instance, to the theft of user data, and they vary depending on the security controls that each IoT prosumer has put in place. To minimize such risks, users might seek an “optimal” set of prosumers. However, assuming the adversary has the same information as the users about the existing security measures, he can then devise which prosumers will be preferable (e.g., with the highest security levels) and attack them more intensively. This paper proposes a decision-support approach that minimizes security risks in the above scenario. We propose a non-cooperative, two-player game entitled Prosumers Selection Game (PSG). The Nash Equilibria of PSG determine subsets of prosumers that optimize users' payoffs. We refer to any game solution as the Nash Prosumers Selection (NPS), which is a vector of probabilities over subsets of prosumers. We show that when using NPS, a user faces the least expected damages. Additionally, we show that according to NPS every prosumer, even the least secure one, is selected with some non-zero probability. We have also performed simulations to compare NPS against two different heuristic selection algorithms. The former is proven to be approximately 38% more effective in terms of security-risk mitigation.

Abstract: Achieving reliability, availability, efficient node repair and security of the data stored in a Distributed Storage System (DSS) is of great importance for improving the functioning of these systems. In this work, we apply a data distribution concept, Twin-code framework, and compare it with a DSS that uses minimum bandwidth regenerating (MBR) and minimum storage regenerating (MSR) codes. We demonstrate that the Twin-code framework gives better performance in the distribution process. Moreover, we construct a new secure Twin MDS code and investigate its security performance comparing to the security of the MBR and MSR codes. The new constructed code is resistant against a threat model where a passive eavesdropper can access to the stored data and the downloaded data during the repair process of a failed node. We demonstrate that the Twin MDS code framework achieves better results than the MBR and MSR codes regarding the security in the system.

Abstract: This paper shows that the maximal correlation between the message and the ciphertext provides good secrecy guarantees for ciphers with short keys. We show that a small maximal correlation ρ can be achieved via a randomly generated cipher with key length ≈ 2 log(1/ρ), independent of the message length, and by a stream cipher with key length ≈ 2 log(1/ρ)+log n for a message of length n. We provide a converse result showing that these ciphers are close to optimal. We then show that any cipher with a small maximal correlation achieves a variant of semantic security with computationally unbounded adversary, similar to entropic security proposed by Russell and Wang. Finally, we show that a small maximal correlation implies secrecy with respect to several mutual information based criteria but is not necessarily implied by them.

Abstract: We examine the side-channel information leakage in first-come-first-serve (FCFS) packet schedulers. In this setup, an attacker aims to learn the packet arrival pattern of a private user that shares a FCFS packet scheduler with him, using the queuing delay information of his own packets. Under an information-theoretic metric for information leakage, we identify the optimal non-adaptive strategy for a given average probe rate of the attacker and report upto 1000% increase in information leakage compared to the attack strategy analyzed in the literature with the same average probe rate. The search for optimal strategies is reduced to linear programming, implying that the discovery of such strategies is in the domain of a real-world attacker.

Abstract: With a large number of sensors and control units in networked systems, the decentralized computing algorithms play a key role in scalable and efficient data processing for detection and estimation. The well-known algorithms are vulnerable to adversaries who can modify and generate data to deceive the system to misclassify or misestimate the information from the distributed data processing. This work aims to develop secure, resilient and distributed machine learning algorithms under adversarial environment. We establish a game-theoretic framework to capture the conflicting interests between the adversary and a set of distributed data processing units. The Nash equilibrium of the game allows predicting the outcome of learning algorithms in adversarial environment, and enhancing the resilience of the machine learning through dynamic distributed learning algorithms. We use Spambase Dataset to illustrate and corroborate our results.

Abstract: Recent technological developments in cloud computing and the ensuing commercial appeal have encouraged companies and individuals to outsource their storage and computations to powerful cloud servers. However, the challenge when outsourcing data and computation is to ensure that the cloud servers comply with their advertised policies. In this paper, we focus in particular on the scenario where a data owner wishes to (i) outsource its public database to a cloud server; (ii) enable anyone to submit multi-keyword search queries to the outsourced database; and (iii) ensure that anyone can verify the correctness of the server's responses. To meet these requirements, we propose a solution that builds upon the well-established techniques of Cuckoo hashing, polynomial-based accumulators and Merkle trees. The key idea is to (i) build an efficient index for the keywords in the database using Cuckoo hashing; (ii) authenticate the resulting index using polynomial-based accumulators and Merkle tree; (iii) and finally, use the root of the Merkle tree to verify the correctness of the server's responses. Thus, the proposed solution yields efficient search and verification and incurs a constant storage at the data owner. Furthermore, we show that it is sound under the strong bilinear Diffie-Hellman assumption and the security of Merkle trees.

Abstract: To preserve the private information of the outsourced database, it is important to encrypt the database. Also it is necessary to provide a query processing scheme without decrypting the encrypted data. For this, we propose a group order preserving data encryption scheme based on periodic functions (GOPES). Our GOPES generates encryption signatures based on data groups and periodic functions. With this, we can guarantee the data privacy.

Cloud computing allows data owners to outsource their databases, eliminating the need for costly storage and computational resources. The main challenge is maintaining data confidentiality with respect to untrusted parties as well as providing efficient and accurate query results to the authenticated users. We propose a dual transformation scheme on the spatial database to overcome this problem, while the service provider executes queries and returns results to the users. First, our approach utilizes the space-filling Hilbert curve to map each spatial point in the multidimensional space to a one-dimensional space. This space transformation method is easy to compute and preserves the spatial proximity. Next, the order-preserving encryption algorithm is applied to the clustered data. The user issues spatial range queries to the service provider on the encrypted Hilbert index and then uses a secret key to decrypt the query response returned. This allows data protection and reduces the query communication cost between the user and service provider.

Abstract: Outsourcing data on the cloud poses many challenges related to data owners and users privacy, especially when some data processing capabilities are delegated to the cloud infrastructure. In this paper we address the problem of executing privacy-preserving equality queries in a scenario where multiple data owners outsource their databases to an untrusted cloud service provider, accepting encrypted queries coming from authorized users. We propose a highly scalable proxy re-encryption scheme so that (i) the cloud service provider can return only the encrypted data that satisfies user's query without decrypting it, and (ii) the encrypted results can be decrypted using the user's key. We analyze the computation efficiency and the security of the scheme against proxy under the standard Diffie-Hellman assumption, reporting also some experimental results, which show encouraging speed up in comparison with previously proposed similar schemes.

Abstract: Cloud computing is an information technology where user can remotely store their outsourced data so as enjoy on demand high quality application and services from configurable resources. Using information data exchange, users can be worried from the load of local data storage and protection. Thus, allowing freely available auditability for cloud data storage is more importance so that user gives change to check data integrity through external audit party. In the direction of securely establish efficient third party auditor (TPA), which has next two primary requirements to be met: 1) TPA should able to audit outsourced data without demanding local copy of user outsourced data; 2) TPA process should not bring in new threats towards user data privacy. To achieve these goals this system will provide a solution that uses Kerberos as a Third Party Auditor/ Authenticator, RSA algorithm for secure communication, MD5 algorithm is used to verify data integrity, Data centers is used for storing of data on cloud in effective manner with secured environment and provides Multilevel Security to Database.

Abstract: There has been a tremendous growth in health data collection since the development of Electronic Medical Record (EMR) systems. Such collected data is further shared and analyzed for diverse purposes. Despite many benefits, data collection and sharing have become a big concern as it threatens individual privacy. In this paper, we propose a secure and private data management framework that addresses both the security and privacy issues in the management of medical data in outsourced databases. The proposed framework ensures the security of data by using semantically-secure encryption schemes to keep data encrypted in outsourced databases. The framework also provides a differentially-private query interface that can support a number of SQL queries and complex data mining tasks. We experimentally evaluate the performance of the proposed framework, and the results show that the proposed framework is practical and has low overhead.

Abstract: Sensor network has become an increasingly attractive and advantageous subject recently. More and more demands of data storage and data query have been raised in soft-defined sensor network. Bonnet et al. [1] investigated the problem of database in sensor network. In most of such scenes, data is stored in server instead of local. For this reason, data security [2] is very important. While encryption of outsourced data protects against many privacy threats, it could not hide the access patterns of the users. Protecting user information from leakage or attackers while guaranteeing high efficiency of query is becoming an important problem of concern. In this paper, we discuss secure range query based on spatial index. We build the spatial index on the client instead of the server to keep the information away from the potential threat. While keeping a high efficiency of query, we not only encrypt the data, but also hide the access patterns. That will greatly reduce the risk of data leakage. We do simulations and prove our design to be practicable and effective.

Abstract: The demand of storing and processing data online grows quickly to adapt to the rapid change of business. It could lead to crisis if the cloud service provider is compromised and data of users are exposed to attackers in plaintext. In this paper, we introduce a practical scheme that dynamically protects and outsources data on demand, as well as propose a corresponding architecture to securely process data in Database Service Provider. After studying over 1300 database models, we believe this scheme can be applied in production with justifiable result.

Abstract: In today's information era, the data is a key asset for any organization. Every organization has a privacy policy for hiding their data in the database, but when they outsource their data to a third party for analysis purpose there is no security measure taken in order to prevent it from being misused. Data Security plays a vital role in the industry and one way to achieve security is to use data masking. The Main objective of data masking is to hide the sensitive data from the outside world. In this paper we propose a few approaches to hide the sensitive data from being accessed by unauthorized users.

Abstract: Recent trend towards cloud computing and outsourcing has led to the requirement for face recognition (FR) to be performed remotely by third-party servers. When outsourcing the FR, client's test image and classification result will be revealed to the servers. Within this context, we propose a novel privacy-preserving (PP) FR algorithm based on randomization. Existing PP FR algorithms are based on homomorphic encryption (HE) which requires higher computational power and communication bandwidth. Since we use randomization, the proposed algorithm outperforms the HE based algorithm in terms of computational and communication complexity. We validated our algorithm using popular ORL database. Experimental results demonstrate that accuracy of the proposed algorithm is the same as the accuracy of existing algorithms, while improving the computational efficiency by 120 times and communication complexity by 2.5 times against the existing HE based approach.

Abstract: Amplified and disrupting cyber-attacks might lead to severe security incidents with drastic consequences such as large property damage, sensitive information breach, or even disruption of the national economy. While traditional intrusion detection and prevention system might successfully detect low or moderate levels of attack, the cooperation among different organizations is necessary to defend against multi-stage and large-scale cyber-attacks. Correlating intrusion alerts from a shared database of multiple sources provides security analysts with succinct and high-level patterns of cyber-attacks - a powerful tool to combat with sophisticate attacks. However, sharing intrusion alert data raises a significant privacy concern among data holders, since publishing this information means a risk of exposing other sensitive information such as intranet topology, network services, and the security infrastructure. This paper discusses possible cryptographic approaches to tackle this issue. Organizers can encrypt their intrusion alert data to protect data confidentiality and outsource them to a shared server to reduce the cost of storage and maintenance, while, at the same time, benefit from a larger source of information for alert correlation process. Two privacy preserving alert correlation techniques are proposed under semi-honest model. These methods are based on attribute similarity and prerequisite/consequence conditions of cyber-attacks.

Abstract: Traditional computation outsourcing and modern cloud computing are affected by a common risk of distrust between service requestor and service provider. We propose a novel protocol, named Probus, that offers guarantees of correct behavior to both parts without assuming any trust relationship between them in the context of cloud-based key-value databases. Probus allows a service requestor to have evidence of cloud provider misbehavior on its data, and a cloud provider to defend itself from false accusations by demonstrating the correctness of its operations. Accusation and defense proofs are based on cryptographic mechanisms that can be verified by a third party. Probus improves the state-of-the-art by introducing novel solutions that allow for efficient verification of data security properties and by limiting the overhead required to provide its security guarantees. Thanks to Probus it is possible to check the correctness of all the results generated by a cloud service, thus improving weaker integrity assurance based on probabilistic verifications that are adopted by related work.

Abstract: Outsourcing databases into cloud increases the need of data security. The user of cloud must be sure that his data will be safe and will not be stolen or reused even if the datacenters were attacked. The service provider is not trustworthy so the data must be invisible to him. Executing queries over encrypted data preserves a certain degree of confidentiality. In this paper, we propose an efficient algorithm to run computations on data encrypted for different principals. The proposed algorithm allows users to run queries over encrypted columns directly without decrypting all records.

Abstract: Cloud computing has greatly facilitated large-scale data outsourcing due to its cost efficiency, scalability and many other advantages. Subsequent privacy risks force data owners to encrypt sensitive data, hence making the outsourced data no longer searchable. Searchable Symmetric Encryption (SSE) is an advanced cryptographic primitive addressing the above issue, which maintains efficient keyword search over encrypted data without disclosing much information to the storage provider. Existing SSE schemes implicitly assume that original user data is centralized, so that a searchable index can be built at once. Nevertheless, especially in cloud computing applications, user-side data centralization is not reasonable, e.g. an enterprise distributes its data in several data centers. In this paper, we propose the notion of Multi-Data-Source SSE (MDS-SSE), which allows each data source to build a local index individually and enables the storage provider to merge all local indexes into a global index afterwards. We propose a novel MDS-SSE scheme, in which an adversary only learns the number of data sources, the number of entire data files, the access pattern and the search pattern, but not any other distribution information such as how data files or search results are distributed over data sources. We offer rigorous security proof of our scheme, and report experimental results to demonstrate the efficiency of our scheme.

Abstract: In storage outsourcing, highly correlated datasets can occur commonly, where the rich information buried in correlated data can be useful for many cloud data generation/dissemination services. In light of this, we propose to enable a secure and efficient cloud-assisted image sharing architecture for mobile devices, by leveraging outsourced encrypted image datasets with privacy assurance. Different from traditional image sharing, the proposed design aims to save the transmission cost from mobile clients, by directly utilizing outsourced correlated images to reproduce the image of interest inside the cloud for immediate dissemination. While the benefits are obvious, how to leverage the encrypted image datasets makes the problem particular challenging. To tackle the problem, we first propose a secure and efficient index design that allows the mobile client to securely find from the encrypted image datasets the candidate selection pertaining to the image of interest for sharing. We then design two specialized encryption mechanisms that support the secure image reproduction inside the cloud directly from the encrypted candidate selection. We formally analyze the security strength of the design. Our experiments show that up to 90% of the transmission cost at the mobile client can be saved, while achieving all service requirements and security guarantees.

Abstract: In our IT society, cloud computing is clearly becoming one of the dominating infrastructures for enterprises as long as end users. As more cloud based services available to end users, their oceans of data are outsourced in the cloud as well. Without any special mechanisms, the data may be leaked to a third party for unauthorized use. Most presented works of cloud computing put these emphases on computing utility or new types of applications. But in the view of cloud users, such as traditional big companies, data in cloud computing systems is tend to be out of control and privacy fragile. So most of data they outsourced is less important. A mechanism to guarantee the ownership of data is required. In this paper, we analyzed a couple of recently presented scalable data management models to describe the storage patterns of data in cloud computing systems. Then we defined a new tree-based dataset management model to solve the storage and sharing problems in cloud computing. A couple of operation strategies including data encryption, data boundary maintenance, and data proof are extracted from the view of different entities in the cloud. The behaviors of different users are controlled by view management on the tree. Based on these strategies, a flexible data management mechanism is designed in the model to guarantee entity privacy, data availability and secure data sharing.

Abstract: Cloud computing encourages the prototype for data service outsourcing, where data owners can avoid cost usage by storing their data in cloud storage centers. The ultimate problem of cloud computing technology is that, the service providers have to protect the user data and services. Secured systems should consider Confidentiality, Availability and Integrity as their primary option. The user encrypts their information to achieve the first one. The second one is achieved in convenient deployment scheme. Last but not the least is integrity. To provide integrity, lots of techniques were discovered, but still the goal is not achieved. In this paper, we propose a novel scheme to achieve integrity goals and we explore how to ensure the integrity and correctness of data storage in cloud computing. The Unique feature of this scheme is finding out which data portion is modified or attacked by the malicious user. In our scheme, there is no need for third-party authority (TPA) and cloud service provider communication in verification. Compared with the existing scheme, it takes the advantage of huge data support and high performance with a simple and easily approachable technique.

Abstract: The advent of the cloud computing makes storage outsourcing become a rising trend, which promotes the secure remote data auditing a hot topic that appeared in the research literature. Recently some research consider the problem of secure and efficient public data integrity auditing for shared dynamic data. However, these schemes are still not secure against the collusion of cloud storage server and revoked group users during user revocation in practical cloud storage system. In this paper, we figure out the collusion attack in the exiting scheme and provide an efficient public integrity auditing scheme with secure group user revocation based on vector commitment and verifier-local revocation group signature. We design a concrete scheme based on the our scheme definition. Our scheme supports the public checking and efficient user revocation and also some nice properties, such as confidently, efficiency, countability and traceability of secure group user revocation. Finally, the security and experimental analysis show that, compared with its relevant schemes our scheme is also secure and efficient.

Abstract: Globalization of the integrated circuit (IC) design industry is making it easy for rogue elements in the supply chain to pirate ICs, overbuild ICs, and insert hardware Trojans. Due to supply chain attacks, the IC industry is losing approximately $4 billion annually. One way to protect ICs from these attacks is to encrypt the design by inserting additional gates such that correct outputs are produced only when specific inputs are applied to these gates. The state-of-the-art logic encryption technique inserts gates randomly into the design, but does not necessarily ensure that wrong keys corrupt the outputs. Our technique ensures that wrong keys corrupt the outputs. We relate logic encryption to fault propagation analysis in IC testing and develop a fault analysis-based logic encryption technique. This technique enables a designer to controllably corrupt the outputs. Specifically, to maximize the ambiguity for an attacker, this technique targets 50% Hamming distance between the correct and wrong outputs (ideal case) when a wrong key is applied. Furthermore, this 50% Hamming distance target is achieved using a smaller number of additional gates when compared to random logic encryption.

Abstract: Due to globalization of Integrated Circuit (IC) design flow, rogue elements in the supply chain can pirate ICs, overbuild ICs, and insert hardware trojans. EPIC [1] locks the design by randomly inserting additional gates; only a correct key makes the design to produce correct outputs. We demonstrate that an attacker can decipher the locked netlist, in a time linear to the number of keys, by sensitizing the key-bits to the output. We then develop techniques to fix this vulnerability and make an attacker’s effort truly exponential in the number of inserted keys.

Abstract: Logic obfuscation can protect designs from reverse engineering and IP piracy. In this paper, a new attack strategy based on applying brute force iteratively to each logic cone is described and shown to significantly reduce the number of brute force key combinations that need to be tried by an attacker. It is shown that inserting key gates based on MUXes is an effective approach to increase security against this type of attack. Experimental results are presented quantifying the threat posed by this type of attack along with the relative effectiveness of MUX key gates in countering it.

Abstract: The threats of reverse-engineering, IP piracy, and hardware Trojan insertion in the semiconductor supply chain are greater today than ever before. Split manufacturing has emerged as a viable approach to protect integrated circuits (ICs) fabricated in untrusted foundries, but has high cost and/or high performance overhead. Furthermore, split manufacturing cannot fully prevent untargeted hardware Trojan insertions. In this paper, we propose to insert additional functional circuitry called obfuscated built-in self-authentication (OBISA) in the chip layout with split manufacturing process, in order to prevent reverse-engineering and further prevent hardware Trojan insertion. Self-tests are performed to authenticate the trustworthiness of the OBISA circuitry. The OBISA circuit is connected to original design in order to increase the strength of obfuscation, thereby allowing a higher layer split and lower overall cost. Additional fan-outs are created in OBISA circuitry to improve obfuscation without losing testability. Our proposed gating mechanism and net selection method can ensure negligible overhead in terms of area, timing, and dynamic power. Experimental results demonstrate the effectiveness of the proposed technique in several benchmark circuits.

Abstract: Logic encryption has recently gained interest as a countermeasure against IP piracy and reverse engineering attacks. A secret key is used to lock/encrypt an IC such that the IC will not be functional without being activated with the correct key. Existing attacks against logic encryption are of theoretical and/or algorithmic nature. In this paper, we evaluate for the first time the security of logic encryption against side-channel attacks. We present a differential power analysis attack against random and strong logic encryption techniques. The proposed attack is highly effective against random logic encryption, revealing more than 70% of the key bits correctly in 50% of the circuits. However, in the case of strong logic encryption, which exhibits an inherent DPA-resistance, the attack could reveal more than 50% of the key bits in only 25% of the circuits.

Abstract: Circuit fingerprinting is a method that adds unique features into each copy of a circuit such that they can be identified for the purpose of tracing intellectual property (IP) piracy. It is challenging to develop effective fingerprinting techniques because each copy of the IP must be made different, which increases the design and manufacturing cost. In this paper, we explore the Observability Don't Care (ODC) conditions to create multiple fingerprinting copies of a design IP (e.g. in the form of gate level layout) with minute changes. More specifically, we find locations in the given circuit layout where we can replace a gate with another gate and some wires without changing the functionality of the circuit. However, as expected, this could introduce design overhead. Our experimental results show that, although we can embed fingerprints of up to 1438 bits, there is an average of 10.9% area increase, 50.5% delay increase, and 9.4% power increase on circuits in the MCNC and ISCAS 85 benchmark suites. We further propose a fingerprinting heuristics under delay constraints to help us reduce area and power overhead.

Abstract: Summary form only given. Reusable hardware intellectual property (IP) based System-on-Chip (SoC) design has emerged as a pervasive design practice in the industry to dramatically reduce design/verification cost while meeting aggressive time-to-market constraints. However, growing reliance on reusable pre-verified hardware IPs and wide array of CAD tools during SoC design - often gathered from untrusted 3rd party vendors - severely affects the security and trustworthiness of SoC computing platforms. Major security issues in the hardware IPs at different stages of SoC life cycle include piracy during IP evaluation, reverse engineering, cloning, counterfeiting, as well as malicious hardware modifications. The global electronic piracy market is growing rapidly and is now estimated to be $1B/day, of which a significant part is related to hardware IPs. Furthermore, use of untrusted foundry in a fabless business model greatly aggravates the SoC security threats by introducing vulnerability of malicious modifications or piracy during SoC fabrication. Due to ever-growing computing demands, modern SoCs tend to include many heterogeneous processing cores, scalable communication network, together with reconfigurable cores e.g. embedded FPGA in order to incorporate logic that is likely to change as standards and requirements evolve. Such design practices greatly increase the number of untrusted components in the SoC design flow and make the overall system security a pressing concern. There is a critical need to analyze the SoC security issues and attack models due to involvement of multiple untrusted entities in SoC design cycle - IP vendors, CAD tool developers, and foundries - and develop low-cost effective countermeasures. These countermeasures would encompass encryption, obfuscation, watermarking and fingerprinting, and certain analytic methods derived from the behavioral aspects of SoC to enable trusted operation with untrusted components. In this tutorial, we plan to prov- de a comprehensive coverage of both fundamental concepts and recent advances in validation of security and trust of hardware IPs. The tutorial also covers the security and debug trade-offs in modern SoCs e.g., more observability is beneficial for debug whereas limited observability is better for security. It examines the state-of-the-art in research in this challenging area as well as industrial practice, and points to important gaps that need to be filled in order to develop a validation and debug flow for secure SoC systems. The tutorial presenters (one industry expert and two faculty members) will be able to provide unique perspectives on both academic research and industrial practices. The selection of topics covers a broad spectrum and will be of interest to a wide audience including design, validation, security, and debug engineers. The proposed tutorial consists of five parts. The first part introduces security vulnerabilities and various challenges associated with trust validation for hardware IPs. Part II covers various security attacks and countermeasures. Part III covers both formal methods and simulation-based approaches for security and trust validation. Part IV presents the conflicting requirements between security and debug during SoC development and ways to address them. Part V covers real-life examples of security failures and successful countermeasures in industry. Finally, Part VI concludes this tutorial with discussion on emerging issues and future directions.

Abstract: A number of studies of hardware security aim to thwart piracy, overbuilding, and reverse engineering (RE) by obfuscating and/or camouflaging. However, these techniques incur high overheads, and integrated circuit (IC) camouflaging cannot provide any protection for the gate-level netlist of the third party intellectual property (IP) core or the single large monolithic IC. In order to circumvent these weaknesses, this brief elaborately analyzes these hardware security techniques and proposes a practical logic obfuscation method with low overheads to prevent an adversary from RE both the gate-level netlist and the layout-level geometry of IP/IC and protect IP/IC from piracy and overbuilding. Experimental evaluations demonstrate the low area, power, and zero performance overhead of the proposed obfuscation technique.

Abstract: The staggering evolution of electronic products in all spheres of human life has been possible because of the advancements in the Integrated Circuit (IC) design and technologies. The complexities of the ICs have grown tremendously over the years, so does the intellectual capital of resources and man years of efforts in their creations. With increasing emphasis on protection of ICs, the issues of Intellectual Property Rights (IPR) pertaining to IC layout, the backbone of implemented functionality, have become crucial. The matters of IPR also touch on several legal and ethical issues associated with the layout creations. In this context, analyzing the distinctness in IC Layout Design (LD) and knowing the unique and common parts in different IC LDs of concern has become important both from IP protection aspects as well as design perspective of tagging the layouts for their content. A robust analytical evaluation of designs could immensely help in catching piracy of IC Designs in addition to assisting the screening processes followed before granting IPR to claimants. Authors have previously presented some results on custom designed IC Layout Design Diagnostic Tool (ICLDDT) for this purpose. In the present paper, the abilities of a more advanced version, Version 2 of this tool is investigated further and results of performance reported.

Abstract: The increasing IC manufacturing cost encourages a business model where design houses outsource IC fabrication to remote foundries. Despite cost savings, this model exposes design houses to IC piracy as remote foundries can manufacture in excess to sell on the black market. Recent efforts in digital hardware security aim to thwart piracy by using XOR-based chip locking, cryptography, and active metering. To counter direct attacks and lower the exposure of unlocked circuits to the foundry, we introduce a multiplexor-based locking strategy that preserves test response allowing IC testing by an untrusted party before activation. We demonstrate a simple yet effective attack against a locked circuit that does not preserve test response, and validate the effectiveness of our locking strategy on IWLS 2005 benchmarks.

Abstract: Over the past 10 years, the designers of intellectual properties (IP) have faced increasing threats including illegal copy or cloning, counterfeiting, reverse-engineering. This is now a critical issue for the microelectronics industry, mainly for fabless designers and FPGA designers. The design of a secure, efficient, lightweight protection scheme for design data is a serious challenge for the hardware security community. In this context, this paper presents the first ultra-lightweight transmitter using side channel leakage based on electromagnetic emanation to send embedded IP identity discreetly and quickly. In addition, we present our electromagnetic test bench and a coherent demodulation method using slippery window spectral analysis to recover data outside the device. The hardware resources occupied by the transmitter represent less than 0.022% of a 130 nm Microsemi Fusion FPGA. Experimental results show that the demodulation method success to provide IP data with a bit rate equal to 500 Kbps.

Abstract: Nowadays, electronics systems design is a complex process. A design-and-reuse model has been adopted, and the vast majority of designers integrate third party intellectual property (IP) cores in their design in order to reduce time to market. Due to their immaterial form and high market value, IP cores are exposed to threats such as cloning and illegal copying. In order to fight these threats, we propose to achieve functional locking, equivalent to a trigger able and reversible denial-of-service. This is done by inserting locking gates at specific locations in the net list, allowing to force outputs at a fixed value. We developed a new method based on graph exploration techniques for locking gates insertion. It selects candidate nodes ten thousand times faster than state-of-the-art fault analysis-based logic masking techniques. Methods are then compared on ISCAS'85 combinational benchmarks.

Abstract: Third-party intellectual property (3PIP) cores are widely used in integrated circuit designs. It is essential and important to ensure their trustworthiness. Existing hardware trust verification techniques suffer from high computational complexity, low extensibility, and inability to detect implicitly-triggered hardware trojans (HTs). To tackle the above problems, in this paper, we present a novel 3PIP trust verification framework, named FASTrust, which conducts HT feature analysis on the flip-flop level control-data flow graph (CDFG) of the circuit. FASTrust is not only able to identify existing explicitly-triggered and implicitly-triggered HTs appeared in the literature in an efficient and effective manner, but more importantly, it also has the unique advantage of being scalable to defend against future and more stealthy HTs by adding new features to the system.

Abstract: Digital watermarks embed information into a host artifact in such a way that the functionalities of the artifact remain unchanged. Allowing for the timely retrieval of authorship/ownership information, and ideally hard to be removed, watermarks discourage piracy and have thus been regarded as important tools to protect the intellectual property. A watermark aimed at uniquely identifying an artifact is referred to as a fingerprint. After presenting a formal definition of digital watermarks, we introduce an unbiased fingerprinting protocol -- based on oblivious transfer -- that lends no advantage to the prosecuting party in a dispute around intellectual property breach.

We also consider current approaches and controls to mitigating the level of such threats by broadly classifying them into two categories.

Abstract: The proof carrying hardware intellectual property (PCHIP) framework ensures trustworthiness by developing proofs for security properties designed to prevent introduction of malicious behaviors via third-party hardware IP. However, converting a design to a formal representation and developing proofs for the desired security properties is a cumbersome task for IP developers and requires extra knowledge of formal reasoning methods, proof development and proof checking. While security properties are generally specific to each design, information flow policies are a set of policies which ensure that no secret information is leaked through untrusted channels, and are mainly applicable to the designs which manipulate secret and sensitive data. In this work, we introduce the VeriCoq-IFT framework which aims to (i) automate the process of converting designs from HDL to the Coq formal language, (ii) generate security property theorems ensuring information flow policies, (iii) construct proofs for such theorems, and (iv) check their validity for the design, with minimal user intervention. We take advantage of Coq proof automation facilities in proving the generated theorems for enforcing these policies and we demonstrate the applicability of our automated framework on two DES encryption circuits. By providing essential information, the trustworthiness of these circuits in terms of information flow policies is verified automatically. Any alteration of the circuit description against information flow policies causes proofs to fail. Our methodology is the first but essential step in the adoption of PCHIP as a valuable method to authenticate the trustworthiness of third party hardware IP with minimal extra effort.

Abstract: As control system networks are being connected to enterprise level networks for remote monitoring, operation, and system-wide performance optimization, these same connections are providing vulnerabilities that can be exploited by malicious actors for attack, financial gain, and theft of intellectual property. Much effort in cyber-physical system (CPS) protection has focused on protecting the borders of the system through traditional information security techniques. Less effort has been applied to the protection of cyber-physical systems from intelligent attacks launched after an attacker has defeated the information security protections to gain access to the control system. In this paper, attacks on actuator signals are analyzed from a system theoretic context. The threat surface is classified into finite energy and bounded attacks. These two broad classes encompass a large range of potential attacks. The effect of theses attacks on a linear quadratic (LQ) control are analyzed, and the optimal actuator attacks for both finite and infinite horizon LQ control are derived, therefore the worst case attack signals are obtained. The closed-loop system under the optimal attack signals is given and a numerical example illustrating the effect of an optimal bounded attack is provided.

Abstract: Plagiarism is an illicit act which has become a prime concern mainly in educational and research domains. This deceitful act is usually referred as an intellectual theft which has swiftly increased with the rapid technological developments and information accessibility. Thus the need for a system/ mechanism for efficient plagiarism detection is at its urgency. In this paper, an investigation of different combined similarity metrics for extrinsic plagiarism detection is done and it focuses on unfolding the importance of combined similarity metrics over the commonly used single metric usage in plagiarism detection task. Further the impact of utilizing part of speech tagging (POS) in the plagiarism detection model is analyzed. Different combinations of the four single metrics, Cosine similarity, Dice coefficient, Match coefficient and Fuzzy-Semantic measure is used with and without POS tag information. These systems are evaluated using PAN1 -2014 training and test data set and results are analyzed and compared using standard PAN measures, viz, recall, precision, granularity and plagdet_score.

Abstract: The prevalent use of systems-on-chip (SoCs) makes them prime targets for software attacks. Proposed security countermeasures monitor software execution in real-time, but are impractical, and require impractical changes to the internal logic of intellectual property (IP) cores. We leverage the software observability provided by the readily available SoC debug architecture to detect attacks without modifying IP cores. We add hardware components to configure the debug architecture for security monitoring, to store a golden software execution model, and to notify a trusted kernel process when an attack is detected.

Abstract: Reusable hardware Intellectual Property (IP) based System-on-Chip (SoC) design has emerged as a pervasive design practice in the industry today. The possibility of hardware Trojans and/or design backdoors hiding in the IP cores has raised security concerns. As existing functional testing methods fall short in detecting unspecified (often malicious) logic, formal methods have emerged as an alternative for validation of trustworthiness of IP cores. Toward this direction, we discuss two main categories of formal methods used in hardware trust evaluation: theorem proving and equivalence checking. Specifically, proof-carrying hardware (PCH) and its applications are introduced in detail, in which we demonstrate the use of theorem proving methods for providing high-level protection of IP cores. We also outline the use of symbolic algebra in equivalence checking, to ensure that the hardware implementation is equivalent to its design specification, thus leaving little space for malicious logic insertion.

Abstract: Application developers are now turning to field-programmable gate array (FPGA) devices for solutions of small to medium volume due to its post-fabrication flexibility. Unfortunately, the existing upfront intellectual property (IP) licensing model for FPGA based third-party IP cores is economically unattractive. The IP bitstreams in transaction are also vulnerable to cloning, misappropriation and reverse engineering. This paper proposes a secure pay-per-use licensing protocol to avoid complicated communication flow and high implementation cost, while preventing the IP rights from being compromised or abused by all parties involved. The protocol guarantees the confidentiality and integrity of the security-critical components and forbids the implementation of licensed IP cores on gray market or counterfeit chips. The public-crypto based core installation module used to self-configure the licensed IP cores occupies only limited FPGA fabrics temporarily.

Abstract: Intellectual Property (IP) verification is a crucial component of System-on-Chip (SoC) design in the modern IC design business model. Given a globalized supply chain and an increasing demand for IP reuse, IP theft has become a major concern for the IC industry. In this paper, we address the trust issues that arise between IP owners and IP users during the functional verification of an IP core. Our proposed scheme ensures the privacy of IP owners and users, by a) generating a privacy-preserving version of the IP, which is functionally equivalent to the original design, and b) employing homomorphically encrypted input vectors. This allows the functional verification to be securely outsourced to a third-party, or to be executed by either parties, while revealing the least possible information regarding the test vectors and the IP core. Experiments on both combinational and sequential benchmark circuits demonstrate up to three orders of magnitude IP verification slowdown, due to the computationally intensive fully homomorphic operations, for different security parameter sizes.

Abstract: With the rapid growth in the development of digital content, the terms security and privacy are very challenging issues. Watermarking is a broad interesting field which provides way in hiding an informal or formal data in another for maintaining intellectual property rights. The key perspectives of watermarking are security, robustness, invisibility and capacity. In the proposed technique the capacity is increased by embedding two RGB images in one RGB image. The invisibility of the hidden information is obtained by employing least significant bit substitution. The security is enhanced using a novel template matching detection scheme. The proposed fragile watermarking system destroys the watermarks when modified or tampered thus providing integrity and authentication features.

Abstract: Network reconnaissance of IP addresses and ports is prerequisite to many host and network attacks. Meanwhile, static configurations of networks and hosts simplify this adversarial reconnaissance. In this paper, we present a novel proactive-adaptive defense technique that turns end-hosts into untraceable moving targets, and establishes dynamics into static systems by monitoring the adversarial behavior and reconfiguring the addresses of network hosts adaptively. This adaptability is achieved by discovering hazardous network ranges and addresses and evacuating network hosts from them quickly. Our approach maximizes adaptability by (1) using fast and accurate hypothesis testing for characterization of adversarial behavior, and (2) achieving a very fast IP randomization (i.e., update) rate through separating randomization from end-hosts and managing it via network appliances. The architecture and protocols of our approach can be transparently deployed on legacy networks, as well as software-defined networks. Our extensive analysis and evaluation show that by adaptive distortion of adversarial reconnaissance, our approach slows down the attack and increases its detectability, thus significantly raising the bar against stealthy scanning, major classes of evasive scanning and worm propagation, as well as targeted (hacking) attacks.

Abstract: Network servers and applications commonly use static IP addresses and communication ports, making themselves easy targets for network reconnaissances and attacks. Port and address hopping is a novel and effective moving target defense (MTD) which hides network servers and applications by constantly changing IP addresses and ports. In this paper, we develop a novel port and address hopping mechanism called Random Port and Address Hopping (RPAH), which constantly and unpredictably mutates IP addresses and communication ports based on source identity, service identity as well as time with high rate. RPAH provides us a more strength and effective MTD mechanism with three hopping frequency, i.e., source hopping, service hopping and temporal hopping. In RPAH networks, the real IPs (rIPs) and real ports (rPorts) remain untouched and packets are routed based on dynamic and temporary virtual IPs (vIPs) of servers. Therefore, messages from adversaries using static, invalid or inactive IP addresses/ports will be detected and denied. Our experiments and evaluation show that RPAH is effective in defense against various internal and external threats such as network scanning, SYN flooding attack and worm propagation, while introducing an acceptable operation overhead.

Abstract: Modbus/TCP is a network protocol for industrial communications encapsulated in TCP/IP network packets. There is an increasing need to test existing Modbus protocol implementations for security vulnerabilities, as devices become accessible even from the Internet. Fuzz testing can be used to discover implementation bugs in a fast and economical way. We present the design and implementation of MTF, a Modbus/TCP Fuzzer. The MTF incorporates a reconnaissance phase in the testing procedure so as to assist mapping the capabilities of the tested device and to adjust the attack vectors towards a more guided and informed testing rather than plain random testing. The MTF was used to test eight implementations of the Modbus protocol and revealed bugs and vulnerabilities that crash the execution, effectively resulting in denial of service attacks using only a few network packets.

Abstract: Cyber attacks are typically preceded by a reconnaissance phase in which attackers aim at collecting critical information about the target system, including information about network topology, services, operating systems, and unpatched vulnerabilities. Specifically, operating system fingerprinting aims at determining the operating system of a remote host in either a passive way, through sniffing and traffic analysis, or an active way, through probing. Similarly, service fingerprinting aims at determining what services are running on a remote host. In this paper, we propose an approach to defeat an attacker's fingerprinting effort through deception. To defeat OS fingerprinting, we manipulate outgoing traffic so that it resembles traffic generated by a host with a different operating system. Similarly, to defeat service fingerprinting, we modify the service banner by intercepting and manipulating certain packets before they leave the host or network. Experimental results show that our approach can efficiently and effectively deceive an attacker.

Abstract: Monitoring of the high-performance computing systems and their components, such as clusters, grids and federations of clusters, is performed using monitoring systems for servers and networks, or Network Monitoring Systems (NMS). These monitoring tools assist system administrators in assessing and improving the health of their infrastructure. A successful attack on the infrastructure monitoring tools grants the attacker elevated power over the monitoring tasks, and eventually over some management functionality of the interface or over hosts running those interfaces. Additionally, detailed and accurate fingerprinting and reconnaissance of a target infrastructure is possible when such interfaces are publicly exposed. A successful reconnaissance allows an attacker to craft an efficient second stage attacks, such as targeted, mimicry and blended attacks. We provide in this paper a comprehensive security analysis of some of the most popular infrastructure monitoring tools for grids, clusters and High-Performance Computing (HPC) systems. We also provide insights based on the infrastructure data openly exposed over the Internet. The wide use of some of the most popular infrastructure monitoring tools makes this data exposure possible. For example, we found such monitoring interfaces to expose infrastructure details of systems inside many high-profile organizations, including two top national laboratories for nuclear research and one top Internet non-profit foundation. We also present our findings on a plethora of web vulnerabilities in the entire version-span of such monitoring tools, and discuss at a high-level the possible attacks. The results of our research allow us to “monitor” an “alarming” mismanagement reality of grid infrastructure. The aim of this work is to raise the awareness about this novel risk to cloud infrastructure.

Abstract: Wireless ad hoc networks have become valuable assets to both the commercial and military communities with applications ranging from industrial control on a factory floor to reconnaissance of a hostile border. In most applications, nodes act as data sources and forward information to a central base station (BS) that may also perform network management tasks. The critical role of the BS makes it a target for an adversary's attack. Even if an ad hoc network employs conventional security primitives such as encryption and authentication, an adversary can apply traffic analysis techniques to find the BS. Therefore, the BS should be kept anonymous to protect its identity, role, and location. Previous work has demonstrated distributed beamforming to be an effective technique to boost BS anonymity in wireless ad hoc networks; however, the increased anonymity and corresponding energy consumption depend on the quality and quantity of selected helper relays. In this paper we present a novel, distributed approach for determining a set of relays per hop that boosts BS anonymity using evidence theory analysis while minimizing energy consumption. The identified relay set is further prioritized using local wireless channel statistics. The simulation results demonstrate the effectiveness our approach.

Abstract: Recently, a botnet based DDoS (Distributed Denial of Service) attack, called target link flooding attack, has been reported that cuts off specific links over the Internet and disconnects a specific region from other regions. Detecting or mitigating the target link flooding attack is more difficult than legacy DDoS attack techniques, since attacking flows do not reach the target region. Although many mitigation schemes are proposed, they detect the attack after it occurs. In this paper, we propose a fast target link flooding attack detection scheme by leveraging the fact that the traceroute packets are increased before the attack caused by the attacker's reconnaissance. Moreover, by analyzing the characteristic of the target link flooding attack that the number of traceroute packets simultaneously increases in various regions over the network, we propose a detection scheme with multiple detection servers to eliminate false alarms caused by sudden increase of traceroute packets sent by legitimate users. We show the effectiveness of our scheme by computer simulations.

Abstract: The term “Advanced Persistent Threat” refers to a well-organized, malicious group of people who launch stealthy attacks against computer systems of specific targets, such as governments, companies or military. The attacks themselves are long-lasting, difficult to expose and often use very advanced hacking techniques. Since they are advanced in nature, prolonged and persistent, the organizations behind them have to possess a high level of knowledge, advanced tools and competent personnel to execute them. The attacks are usually preformed in several phases - reconnaissance, preparation, execution, gaining access, information gathering and connection maintenance. In each of the phases attacks can be detected with different probabilities. There are several ways to increase the level of security of an organization in order to counter these incidents. First and foremost, it is necessary to educate users and system administrators on different attack vectors and provide them with knowledge and protection so that the attacks are unsuccessful. Second, implement strict security policies. That includes access control and restrictions (to information or network), protecting information by encrypting it and installing latest security upgrades. Finally, it is possible to use software IDS tools to detect such anomalies (e.g. Snort, OSSEC, Sguil).

Abstract: Spear phishing is a widespread concern in the modern network security landscape, but there are few metrics that measure the extent to which reconnaissance is performed on phishing targets. Spear phishing emails closely match the expectations of the recipient, based on details of their experiences and interests, making them a popular propagation vector for harmful malware. In this work we use Natural Language Processing techniques to investigate a specific real-world phishing campaign and quantify attributes that indicate a targeted spear phishing attack. Our phishing campaign data sample comprises 596 emails - all containing a web bug and a Curriculum Vitae (CV) PDF attachment - sent to our institution by a foreign IP space. The campaign was found to exclusively target specific demographics within our institution. Performing a semantic similarity analysis between the senders' CV attachments and the recipients' LinkedIn profiles, we conclude with high statistical certainty (p <; 10-4) that the attachments contain targeted rather than randomly selected material. Latent Semantic Analysis further demonstrates that individuals who were a primary focus of the campaign received CVs that are highly topically clustered. These findings differentiate this campaign from one that leverages random spam.

Abstract: This paper aims at inferring probing campaigns by investigating dark net traffic. The latter probing events refer to a new phenomenon of reconnaissance activities that are distinguished by their orchestration patterns. The objective is to provide a systematic methodology to infer, in a prompt manner, whether or not the perceived probing packets belong to an orchestrated campaign. Additionally, the methodology could be easily leveraged to generate network traffic signatures to facilitate capturing incoming packets as belonging to the same inferred campaign. Indeed, this would be utilized for early cyber attack warning and notification as well as for simplified analysis and tracking of such events. To realize such goals, the proposed approach models such challenging task as a problem of interpolating and predicting time series with missing values. By initially employing trigonometric interpolation and subsequently executing state space modeling in conjunction with a time-varying window algorithm, the proposed approach is able to pinpoint orchestrated probing campaigns by only monitoring few orchestrated flows. We empirically evaluate the effectiveness of the proposed model using 330 GB of real dark net data. By comparing the outcome with a previously validated work, the results indeed demonstrate the promptness and accuracy of the proposed approach.

Abstract: In recent years, Wireless Sensor Networks (WSNs) have become valuable assets to both the commercial and military communities with applications ranging from industrial control on a factory floor to reconnaissance of a hostile border. In most applications, the sensors act as data sources and forward information generated by event triggers to a central sink or base station (BS). The unique role of the BS makes it a natural target for an adversary that desires to achieve the most impactful attack possible against a WSN with the least amount of effort. Even if a WSN employs conventional security mechanisms such as encryption and authentication, an adversary may apply traffic analysis techniques to identify the BS. This motivates a significant need for improved BS anonymity to protect the identity, role, and location of the BS. Previous work has proposed anonymity-boosting techniques to improve the BS's anonymity posture, but all require some amount of overhead such as increased energy consumption, increased latency, or decreased throughput. If the BS understood its own anonymity posture, then it could evaluate whether the benefits of employing an anti-traffic analysis technique are worth the associated overhead. In this paper we propose two distributed approaches to allow a BS to assess its own anonymity and correspondingly employ anonymity-boosting techniques only when needed. Our approaches allow a WSN to increase its anonymity on demand, based on real-time measurements, and therefore conserve resources. The simulation results confirm the effectiveness of our approaches.

Abstract: DDoS attacks have been a persistent threat to network availability for many years. Most of the existing mitigation techniques attempt to protect against DDoS by filtering out attack traffic. However, as critical network resources are usually static, adversaries are able to bypass filtering by sending stealthy low traffic from large number of bots that mimic benign traffic behavior. Sophisticated stealthy attacks on critical links can cause a devastating effect such as partitioning domains and networks. In this paper, we propose to defend against DDoS attacks by proactively changing the footprint of critical resources in an unpredictable fashion to invalidate an adversary's knowledge and plan of attack against critical network resources. Our present approach employs virtual networks (VNs) to dynamically reallocate network resources using VN placement and offers constant VN migration to new resources. Our approach has two components: (1) a correct-by-construction VN migration planning that significantly increases the uncertainty about critical links of multiple VNs while preserving the VN placement properties, and (2) an efficient VN migration mechanism that identifies the appropriate configuration sequence to enable node migration while maintaining the network integrity (e.g., avoiding session disconnection).

Abstract: Penetration testing (or “pentesting”) is critical to both maintaining and increasing the reliability of computer networks while lessening their vulnerability. The number, importance and value of these networks has been growing over the past decade, and their capabilities and respective uses have been integrated into many aspects of our lives. Without penetration testing, our networks can fall victim to a myriad of malicious mayhem which has the potential for serious, large-scale ramifications, and when these networks are not operating as expected it is often individuals who suffer. However, penetration testing poses its own new and diverse set of problems to security analysts. Due to the abstract nature of performing a pentest, the near complete lack of design geared toward effective collaboration and teamwork in many widely used penetration testing tools can create a notable hindrance for security teams. This paper describes a software project surrounding network penetration testing from a collaborative standpoint and the problems associated with team-based efforts utilizing present network analysis tools and technologies.

Abstract: Currently critical infrastructures such as SCADA systems are increasingly under threat, they often go unreported. There is a great need in addressing them. Today majority of the industries use these SCADA systems, so it is very critical to protect these systems. Attack on these systems could cause serious damage to the infrastructure and sometimes a threat to human life as well. As per date there are very few solutions to address SCADA security. So, it is important to take countermeasures against the attacks on these systems. In this paper we will analyze the use of honeypot systems in detecting the network attack vectors on SCADA systems. We will start by analyzing and testing various honeypot features which can help in providing additional security for SCADA systems. A Honeypot is built to mimic the services of an ICS; exposing them to the Internet, making them attractive for attackers and monitor the attackers activities. The goal is to model the attacking methodologies and suggest recommendations to make SCADA system secure.

Abstract: Today's capability of fast Internet-wide scanning allows insights into the Internet ecosystem, but the on-going transition to the new Internet Protocol version 6 (IPv6) makes the approach of probing all possible addresses infeasible, even at current speeds of more than a million probes per second. As a consequence, the exploitation of frequent patterns has been proposed to reduce the search space. Current patterns are manually crafted and based on educated guesses of administrators. At the time of writing, their adequacy has not yet been evaluated. In this paper, we assess the idea of pattern-based scanning for the first time, and use an experimental set-up in combination with three real-world data sets. In addition, we developed a pattern-based algorithm that automatically discovers patterns in a sample and generates addresses for scanning based on its findings. Our experimental results confirm that pattern-based scanning is a promising approach for IPv6 reconnaissance, but also that currently known patterns are of limited benefit and are outperformed by our new algorithm. Our algorithm not only discovers more addresses, but also finds implicit patterns. Furthermore, it is more adaptable to future changes in IPv6 addressing and harder to mitigate than approaches with manually crafted patterns.

Abstract: The topology of networks typically remains static over long periods of time, giving attackers the advantage of long planning cycles to develop, test, and refine targeted attacks. The CINDAM design preempts the attacker by creating ephemeral, per-host views of the protected enclave to transform the constant topology of computing networks into deceptive, mutable, and individualized ones that are able to impede nation-state attacks while still providing mission services to legitimate users. CINDAM achieves this deception without affecting network operations and without modifying client and server software. CINDAM is being implemented using software-defined networking technology for a cost-effective cyber deception solution.

Abstract: Zero-day attack is a critical network attack. The zero-day attack period (ZDAP) is the period from the release of malware/exploit until a patch becomes available. IDS/IPS cannot effectively block zero-day attacks because they use pattern-based signatures in general. This paper proposes a Prophetic Defender (PD) by which ZDAP can be minimized. Prior to actual attack, hackers scan networks to identify hosts with vulnerable ports. If this port scanning can be detected early, zero-day attacks will become detectable. PD architecture makes use of a honeypot-based pseudo server deployed to detect malicious port scans. A port-scanning honeypot was operated by us in 6 years from 2009 to 2015. By analyzing the 6-year port-scanning log data, we understand that PD is effective for detecting and blocking zero-day attacks. The block rate of the proposed architecture is 98.5%.

Abstract: A botnet is group of compromised computers that are controlled by a botmaster, who uses them to perform illegal activities. Centralized and P2P (Peer-to-Peer) botnets are the most commonly used botnet types. Honeypots have been used in many systems as computer defense. They are used to attract botmasters to add them in their botnets; to become spies in exposing botnet attacker behaviors. In recent research works, improved mechanisms for honeypot detection have been proposed. Such mechanisms would enable bot masters to distinguish honeypots from real bots, making it more difficult for honeypots to join botnets. This paper presents a new method that can be used by security defenders to overcome the authentication procedure used by the advanced two-stage reconnaissance worm (ATSRW). The presented method utilizes the peer list information sent by an infected host during the ATSRW authentication process and uses a combination of IP address spoofing and fake TCP three-way handshake. The paper provides an analytical study on the performance and the success probability of the presented method. We show that the presented method provide a higher chance for honeypots to join botnets despite security measures taken by botmasters.

Abstract: Critical infrastructure control systems continue to foster predictable communication paths and static configurations that allow easy access to our networked critical infrastructure around the world. This makes them attractive and easy targets for cyber-attack. We have developed technologies that address these attack vectors by automatically reconfiguring network settings. Applying these protective measures will convert control systems into "moving targets" that proactively defend themselves against attack. This "Moving Target Defense" (MTD) revolves about the movement of network reconfiguration, securely communicating reconfiguration specifications to other network nodes as required, and ensuring that connectivity between nodes is uninterrupted. Software-defined Networking (SDN) is leveraged to meet many of these goals. Our MTD approach eliminates adversaries targeting known static attributes of network devices and systems, and consists of the following three techniques: (1) Network Randomization for TCP/UDP Ports; (2) Network Randomization for IP Addresses; (3) Network Randomization for Network Paths In this paper, we describe the implementation of the aforementioned technologies. We also discuss the individual and collective successes for the techniques, challenges for deployment, constraints and assumptions, and the performance implications for each technique.

Abstract: Recent technological advancements and increasing potential applications have led to the use of Wireless Sensor Networks in various fields. Since the sensor nodes are usually deployed in places where there is no human surveillance, these networks are highly vulnerable to various security threats. The memory, power and processing constraints of the sensor nodes pose challenges to developing efficient security algorithms. Although many cryptographic techniques have been proposed to mitigate outside attacks, the securing of networks against inside attacks has not been addressed effectively. In this paper, a novel security system has been proposed to address the overall security requirement for Wireless Sensor Networks. Defense against outside attacks is provided using a cluster-based authentication and key management scheme using Elliptic Curve Cryptography, while inside attacks are taken care by a Hybrid Intrusion Detection System using Bayesian probabilistic model for decision making. The simulation results show the overall effectiveness of the proposed scheme, revealing better performance in terms of resilience to outside attacks, memory capacity, energy efficiency and false alarm rate.

Abstract: Shipboard networked control systems are based on a distributed control system architecture that provides remote and local control monitoring. In order to allow the network to scale a hierarchical communication network is composed of highspeed Ethernet based network switches. Ethernet is the prevalent medium to transfer control data, such as control signals, alarm signal, and sensor measurements on the network. However, communication capabilities bring new security vulnerabilities and make communication links a potential target for various kinds of cyber/physical attacks. The goal of this work is to implement and demonstrate a network layer attack against networked control systems, by tampering with temporal characteristics of the network, leading to time varying delays and packet scheduling abnormalities.

Abstract: We address the problems of network and reconfiguration attacks on an industrial control system (ICS) by describing a trustworthy autonomic interface guardian architecture (TAIGA) that provides security against attacks originating from both supervisory and plant control nodes. In contrast to the existing security techniques which attempt to bolster perimeter security at supervisory levels, TAIGA physically isolates trusted defense mechanisms from untrusted components and monitors the physical process to detect an attack. Trusted components in TAIGA are implemented in programmable logic (PL). Our implementation of TAIGA integrates a trusted safety-preserving backup controller, and a mechanism for preemptive switching to a backup controller when an attack is detected. A hardware implementation of our approach on an inverted pendulum system illustrates how TAIGA improves resilience against software reconfiguration and network attacks.

Abstract: The growing connectivity of cyber-physical systems (CPSes) has led to an increased concern over the ability of cyber-attacks to inflict physical damage. Current cyber-security measures focus on preventing attacks from penetrating control supervisory networks. These reactive techniques, however, are often plagued with vulnerabilities and zero-day exploits. Embedded processors in CPS field devices often possess little security of their own, and are easily exploited once the network is penetrated. We identify four possible outcomes of a cyber-attack on a CPS embedded processor. We then discuss five trust requirements that a device must satisfy to guarantee correct behavior through the device's lifecycle. Next, we examine the Trustworthy Autonomic Interface Guardian Architecture (TAIGA) which monitors communication between the embedded controller and physical process. This autonomic architecture provides the physical process with a last line of defense against cyber-attacks. TAIGA switches process control to a trusted backup controller if an attack causes a system specification violation. We conclude with experimental results of an implementation of TAIGA on a hazardous cargo-carrying robot.

Abstract: The economic machinery of the United States is reliant on complex large-scale cyber-physical systems which include electric power grids, oil and gas systems, transportation systems, etc. Protection of these systems and their control from security threats and improvement of the robustness and resilience of these systems, are important goals. Since all these systems have Supervisory Control and Data Acquisition (SCADA) in their control centers, a number of test beds have been developed at various laboratories. Usually on such test beds, people are trained to operate and protect these critical systems. In this paper, we describe a virtualized distributed test bed that we developed for modeling and simulating SCADA applications and to carry out related security research. The test bed is a virtualized by integrating various heterogeneous simulation components. This test bed can be reconfigured to simulate the SCADA of a power system, or a transportation system or any other critical systems, provided a back-end domain specific simulator for such systems are attached to it. In this paper, we describe how we created a scalable architecture capable of simulating larger infrastructures and by integrating communication models to simulate different network protocols. We also developed a series of middleware packages that integrates various simulation platforms into our test bed using the Python scripting language. To validate the usability of the test bed, we briefly describe how a power system SCADA scenario can be modeled and simulated in our test bed.

Abstract: Wireless Sensor and Actuator Networks has become an important area of research. They can provide flexibility, low operational and maintenance costs and they are inherently scalable. In the realm of Internet of Things the majority of devices is able to communicate with one another, and in some cases they can be deployed with an IP address. This feature is undoubtedly very beneficial in wireless sensor and actuator networks applications, such as monitoring and control systems. However, this kind of communication infrastructure is rather challenging as it can compromise the overall system performance due to several factors, namely outliers, intermittent communication breakdown or security issues. In order to improve the overall resilience of the system, this work proposes a distributed hierarchical multi-agent architecture implemented over a IPv6 communication infrastructure. The Contiki Operating System and RPL routing protocol were used together to provide a IPv6 based communication between nodes and an external network. Experimental results collected from a laboratory IPv6 based WSAN test-bed, show the relevance and benefits of the proposed methodology to cope with communication loss between nodes and the server.

Abstract: Limited scalability, reliability, and security of today’s utility communication infrastructures are main obstacles to the deployment of smart grid applications. The C-DAX project aims at providing and investigating a communication middleware for smart grids to address these problems, applying the information-centric networking and publish/subscribe paradigm. We briefly describe the C-DAX architecture, and extend it with a flexible resilience concept, based on resilient data forwarding and data redundancy. Different levels of resilience support are defined, and their underlying mechanisms are described. Experiments show fast and reliable performance of the resilience mechanism.

Abstract: Networked infrastructures underpin most social and economical interactions nowadays and have become an integral part of the critical infrastructure. Thus, it is crucial that heterogeneous networked environments provide adequate resilience in order to satisfy the quality requirements of the user. In order to achieve this, a coordinated approach to confront potential challenges is required. These challenges can manifest themselves under different circumstances in the various infrastructure components. The objective of this paper is to present a multi-level resilience approach that goes beyond the traditional monolithic resilience schemes that focus mainly on one infrastructure component. The proposed framework considers four main aspects, i.e. users, application, network and system. The latter three are part of the technical infrastructure while the former profiles the service user. Under two selected scenarios this paper illustrates how an integrated approach coordinating knowledge from the different infrastructure elements allows a more effective detection of challenges and facilitates the use of autonomic principles employed during the remediation against challenges.

Abstract: Hardware Trojans compromise security by invalidating the assumption that hardware provides a root-of-trust for secure systems. We propose a novel approach for an FPGA system-on-chip (SoC) to ensure confidentiality of trusted software despite hardware Trojan attacks. Our approach employs defensive techniques that feature morphing on-chip resources for moving target defense against fabrication-time Trojans, onion-encryption for confidentiality, and replication of functionally-equivalent variants of processing elements with arbitrated voting for resilience to design-time Trojans. These techniques are enabled by partial runtime reconfiguration (PRR) and are managed by a hardware abstraction layer (HAL) that reduces developer burden. We call our approach the Morph Onion-encryption Replication PRR HAL, or MORPH. MORPH aims to provide a stable interface for embedded systems developers to use in deploying applications that are resilient to hardware Trojans.

Abstract: The network has become essential to all aspects of modern life and thus the consequences of network disruption have become increasingly severe.

Abstract: Access control systems have been widely used in physical security to authenticate the passing people and control their entrance. The existing systems can be classified into the fingerprint based system, the proximity card based system, etc. according to the adopted authentication techniques. However, proximity cards are easy to lose, while fingerprints also become less reliable because they can be copied to make fakes. It appears access control systems relying on only one single authentication technique can be really risky. In this paper, we improve the traditional fingerprint based access control system with an additional authentication process and a remote authorization scheme, both of which are based on Quick Response Code (QR code). The second authentication process leverages the one-time password (OTP) and the personalized response to a challenge contained in the QR code to enhance security. The authorization scheme assists a remote manager to grant temporary access to otherwise unauthorized personnel using the time-stamped authorization information stored in the QR code. We have implemented the prototype of the proposed system in the .NET framework. Our experiments show the prototype takes about 77 ms to offer more rigorous authentication and 134 ms to provide both strengthened authentication and authorization.

Abstract: The proliferation of technology paves way to new kind of devices that can communicate with other devices to produce output mostly on wireless communication. Wirelessly communicating embedded devices are brought to one another in a single link over Internet called IoT (Internet of Things). If all objects and people in daily life were equipped with identifiers, computers could manage and inventory them. Besides using RFID, the tagging of things may be achieved through such technologies as near field communication, barcodes, QR codes and digital watermarking. Here new method of using embedded technology to provide such application, Arduino is used as an embedded controller to interface Ethernet shield with a PC/Laptop to provide IoT over Ethernet. A user can use this parking service in the airport scenario provided by airport authority with user ID and password. Whenever a user need to check the vehicle in the parking lot, uses the ID and password to logon into the airport web link and view the status of the car in the parking lot using IoT. IoT Based Airport Parking System is discussed here to implement Arduino environment as IoT application.

Abstract: The reach of information is now much easier and effective in the age of information technology. Electronic documents and resources have changed the entire paradigm of education and research. Students, teachers, professionals, academicians and researchers may get their information on their desktop/laptop/Smartphone through electronic platform. The availability of Information and Communication Technology (ICT) and their use has also produced some challenges amongst the library professionals to make optimum use of information resources available. It has been observed that in spite of awareness programs, several e-resources are being underutilized or less used. There are several tools which may be used to raise the usage of e-resources to the maximum. One of them is QR Code technology. Quick Response codes are basically made for product promotion more likely as Bar-codes. In this paper a working model is presented which can be used in the Libraries to maximize the usage of e-books and other products and services of the Library.

Abstract: The popularity of QR code clearly indicates the strong demand of users to acquire (or pull) further information from interested sources (e.g., a poster) in the physical world. However, existing information pulling practices such as a mobile search or QR code scanning incur heavy user involvement to identify the targeted posters. Meanwhile, businesses (e.g., advertisers) are also interested to learn about the behaviors of potential customers such as where, when, and how users show interests in their offerings. Unfortunately, little such context information are provided by existing information pulling systems. In this paper, we present Contextual-Code (C-Code) - an information pulling system that greatly relieves users' efforts in pulling information from targeted posters, and in the meantime provides rich context information of user behavior to businesses. C-Code leverages the rich contextual information captured by the smartphone sensors to automatically disambiguate information sources in different contexts. It assigns simple codes (e.g., a character) to sources whose contexts are not discriminating enough. To pull the information from an interested source, users only need to input the simple code shown on the targeted source. Our experiments demonstrate the effectiveness of C-Code design. Users can effectively and uniquely identify targeted information sources with an average accuracy over 90%.

Abstract: Barcodes have been long used for data storage. Detecting and locating barcodes in images of complex background is an essential yet challenging step in the process of automatic barcode reading. This work proposed an algorithm that localizes and segments two-dimensional quick response (QR) barcodes. The localization involved a convolutional neural network that could detect partial QR barcodes. Majority voting was then applied to determine barcode locations. Then image processing algorithms were implemented to segment barcodes from the background. Experimental results show that the proposed approach was robust to detect QR barcodes with rotation and deformation.

Abstract: There is a growing interest in integrating public transportation with the smartphone and mobile ticketing provides just that. To do so, different technologies can be used, such as Near Field Communication, Quick Response Codes and Bluetooth Low Energy. This paper explores the possibility of implementing a mobile ticketing solution, with focus on the ticket validation process, using these technologies. They are analyzed and compared at different levels and two possible approaches proposed. Both solutions are presented in terms of infrastructure and maintenance cost, as well as passenger interaction and benefit. The feasibility and performance of the technologies is analyzed and presented in the context of the proposed approaches. As a result, a mobile ticketing solution can be implemented using different technologies, and their choice depends on factors such as the available funds, the intended interaction level, performance and the size of the target audience.

Abstract: The barcode technology has undergone many dramatic changes during the past few years. This is due to the increased need for encoding more data into the barcode. One of the latest developments in the barcode technology is color barcode, developed by Microsoft's High Capacity Color Barcode (HCCB). With four or eight colors, color barcodes are now used extensively in certain areas such as airports, print advertising and mobile phones compared to the 2D black and white barcodes such as Quick Response (QR) code and data matrix. This paper provides an overview of six papers related to color barcode and later introduces an algorithm developed to encode data using binarization and grouping of bits to form a color barcode and also to decode data from color barcode.

Abstract: Quick Response (QR) codes are two-dimensional (2-D) barcodes that can contain information such as URL links (e.g. a link to YouTube video, website link) and text (e.g. contact details, product details). These square pattern codes consist of black modules on a white background. QR code generator is software that stores data (e.g. URL link, text, Google maps location) into a QR code. This encoded data can be decoded by scanning the QR code symbol with a mobile device that is equipped with a camera and a QR code reader software. QR codes have a number of purposes; they are mostly used in manufacturing (e.g. product traceability, process control, inventory and equipment management), warehousing and logistics (e.g. item tracking), retailing (e.g. sales management), healthcare (e.g. medical records management, patient identification, equipment and device tracking), transportation (e.g. ticketing and boarding passes), office automation (e.g. document management), marketing and advertising (e.g. mobile marketing, electronic tickets, coupons, payments). This paper will describe various methods for the implementation of QR codes in the educational process. Experience from the School of Electrical Engineering in Zagreb shows that QR codes supports both independent and collaborative learning and can create an interactive learning environment.

Abstract: Mobile-based Assessment is increasingly used in different educational settings. Its successful implementation though depends on user acceptance. While previous research provides evidence on acceptance of mobile learning and computer-based assessment, there are not many studies focusing explicitly on the acceptance of Mobile-based Assessment. This study examines the impact of Perceived Mobility, Satisfaction, Perceived Usefulness and Perceived Ease of Use on students' Behavioral Intention to Use Mobile-based Assessment. 47 secondary school students, using their mobile devices and Quick Response (QR) - coding technology, participated in an outdoor Mobile-based Assessment procedure during their visit in a Botanic Garden. Partial Least Squares (PLS) was used for the data analysis of the recorded students' perceptions about the Mobile-based Assessment. Results show that Perceived Mobility, Satisfaction, Perceived Usefulness and Perceived Ease of Use are all significant determinants of Behavioral Intention to Use mobile-based assessment. Several important implications for designing and implementing mobile-based assessment procedures are discussed.

Abstract: The conventional optical cable labels in smart substations contain too little information to support operation or maintenance. To solve this problem, this paper introduced a QR (Quick Response) code system for labeling and identification of optical cable labels in China's smart substations. The label format is specified for three kinds of cables, and the implementation methods of generation module and identification module are also stated. The generation module can provide design drawings of secondary system, QR code labels and database for handheld terminals. The identification module can quickly identify the optical cable by scanning the QR code and show its physical connection and virtual circuit to users. In that way, scan-and-read for signal circuits is achieved, which improves the efficiency of commissioning, operation and maintenance work in smart substations.
