Trustworthy Systems, Part 2 |
Trust is created in information security to assure the identity of external parties. It is one of the core problems. The growth of large-scale distributed systems and outsourcing to cloud increases both the need and the challenge to address trustworthy systems. The works cited here are from 2014 conferences.
Msadek, N.; Kiefhaber, R.; Ungerer, T., "A Trust- and Load-Based Self-Optimization Algorithm for Organic Computing Systems," Self-Adaptive and Self-Organizing Systems (SASO), 2014 IEEE Eighth International Conference on, pp.177,178, 8-12 Sept. 2014. doi: 10.1109/SASO.2014.32 Abstract: In this paper a new design of self optimization for organic computing systems is investigated. Its main task, i.e., beside load-balancing, is to assign services with different importance levels to nodes so that the more important services are assigned to more trustworthy nodes. The evaluation results showed that the proposed algorithm is able to balance the workload between nodes nearly optimal. Moreover, it improves significantly the availability of important services.

Morisse, M.; Horlach, B.; Kappenberg, W.; Petrikina, J.; Robel, F.; Steffens, F., "Trust in Network Organizations — A Literature Review on Emergent and Evolving Behavior in Network Organizations," System Sciences (HICSS), 2014 47th Hawaii International Conference on, pp.4578,4587, 6-9 Jan. 2014. doi:10.1109/HICSS.2014.561 Abstract: This systematic literature review examines different forms of evolving and emergent behavior in network organizations (NO) with an emphasis on trust. Because of the difficulties and importance in researching emergent behavior in network organizations, this review summarizes the main aspects of 17 papers and tries to disclose open research points by combining the different perspectives of behavior and forms of NOs. Due to the complexity of those organizations, there are several “soft aspects” that affect the partnership implicitly. In particular, trust is intertwined with other facets (e.g. legal aspects). IT governance and IT systems can have an impact on trust and vice versa. Therefore, maintaining a trustworthy relationship in a network organization is undoubtedly an enormous challenge for all participants. At the end of this literature review, we discuss some open research gaps like the influence of different cultures in NOs or the visualization of emergent behavior.

Franklin, Z.R.; Patterson, C.D.; Lerner, L.W.; Prado, R.J., "Isolating Trust in an Industrial Control System-on-Chip Architecture," Resilient Control Systems (ISRCS), 2014 7th International Symposium on pp.1,6, 19-21 Aug. 2014. doi:10.1109/ISRCS.2014.6900096 Abstract: A distributed industrial control system (ICS) also distributes trust across many software and hardware components. There is a need for some malware countermeasures to be independent of application, supervisory or driver software, which can introduce vulnerabilities. We describe the Trustworthy Autonomic Interface Guardian Architecture (TAIGA) that provides an on-chip, digital, security version of classic mechanical interlocks. In order to enhance trust in critical embedded processes, TAIGA redistributes responsibilities and authorities between a Programmable Logic Controller (PLC) processor and a hardware-implemented interface controller, simplifying PLC software without significantly degrading performance while separating trusted components from updatable software. The interface controller is synthesized from C code, formally analyzed, and permits runtime checked, authenticated updates to certain system parameters but not code. TAIGA's main focus is ensuring process stability even if this requires overriding commands from the processor or supervisory nodes. The TAIGA architecture is mapped to a commercial, configurable system-on-chip platform.

A mechanism which can distinguish a trustworthy node from an untrustworthy one is essential. The effectiveness of the mechanism depends on the accuracy of node's reputation. Dynamics of Trust often happens in a trusted network. It causes intoxication and disguise for nodes, resulting in abnormal behaviors. This paper proposes a semi-distributed reputation mechanism based on Dynamic Data-Driven Application System. It focuses on the Dynamics of Trust and the balance between Distributed Nodes and the Central Controller. The experimental results show that the proposed mechanism upload only averages 52.21% of the data to compare with all of uploads. It can also effectively handle the problem of Dynamics of Trust.

In weigh against to conventional solutions where all type of computing services are controlled through any type of personnel controls, it transfers all computing resources to the centralized large data centers, so users can enjoy services in a large scale on demand. Chiefly small and medium-size organizations can manage their projects by using cloud-based services and also able to achieve productivity enhancement with limited budgets. But, apart from all of these benefits, it may not be fully trustworthy. Cloud Computing do not keep data on the user's system, so there is a need of data security. The user pays progressively attention about data security due to this off-side storage of data on cloud computing. In order to retain confidentiality of data against un-trusted cloud service providers, There are so many approaches. All modern cloud service providers solve this problem by encryption and decryption techniques. They all have their merits and demerits. In present thesis, the basic dilemma of cloud computing security is inspected. We have also proposed a survey of various models for cloud security. To ensure the data security in the cloud, we suggest an efficient, accessible and adaptable cryptography based scheme. In-depth security and enactment inspection proved the proposed scheme as greatly efficient and robust against spiteful data alteration outbreak. The proposed scheme achieves scalability as well as flexibility due to its hierarchical structure.

The privacy risk is evaluated by the detection cost of the eavesdropper which is assumed to be informed and greedy. It is shown that the optimal detection strategy of the sensor whose decision is eavesdropped on is a likelihood-ratio test. This fundamental insight allows for the optimization to reuse known algorithms extended to incorporate the privacy constraint. The trade-off between the detection performance and privacy risk is illustrated in a numerical example. The incorporation of physical layer privacy in the system design will lead to trustworthy sensor networks in future.

However the adoption issues for the cloud is mainly due to the lack of transparency and control. Also, there are too many cloud service providers in the marketplace offering similar functionalities. In order to support the consumers in identifying trustful cloud providers, Trustworthy mechanisms for selecting cloud service providers is proposed in this paper. The proposed system is implemented using feedbacks and credential attributes (QoS) of providers. A modified Identity model is proposed to identify malicious feedbacks and provides improvements in the trust computation. Results show that the trust computation using the proposed architecture is more efficient in terms of finding accurate trust based providers.

Commercial ports are the main gateways and face increased requirements, responsibilities and needs in view of a secure and sustainable maritime digital environment. Therefore, they have to rely on complicated and advanced facilities, ICT infrastructure and trustworthy e-maritime services in order to optimize their operations. This paper aims at alleviating this gap on the basis of a holistic approach that addresses the security of the dual nature of ports' Critical Information Infrastructures (CIIs). In particular, it introduces a collaborative security management system (CYSM system), which enables ports' operators to: (a) model physical and cyber assets and interdependencies; (b) analyse and manage internal / external / interdependent physical and cyber threats / vulnerabilities; and (c) evaluate / manage physical and cyber risks against the requirements specified in the ISPS Code and ISO27001.

It becomes more and more crucial for a user to know which mobile application is trustworthy to purchase, download, install, execute and recommend. This paper presents the design and implementation of a trust-behavior based reputation system for mobile applications based on an Android platform. The system can automatically evaluate a user's trust in a mobile application based on application usage and generate application reputation according to collected individual trust information. We implement the system and evaluate its performance based on a user study. The result shows that our system is effective with regard to trust/reputation evaluation accuracy, power efficiency and system usability.

Organizations, now a days are in the marathon of equipping the whole system in a cloud form. The attackers evaluating data for a long time to extract the valued information to perform data mining based attacks on the cloud. In the recent architectures the data is sited in a single or distributed cloud provider. It gives the opportunity to the cloud providers and attackers to unauthorized access from cloud and also gives the chance to analyze the client data for a long time to extract the sensitive information, which is responsible for the privacy violation of clients. This paper proposes an approach that firstly maintains the confidentiality, integrity, and authentication for the stored data in cloud. Secondly, it presents distributed storage cloud architecture, which includes the description of trusted computing work group (TCG) and trusted platform module (TPM). It provides hardware authentication for trustworthy computing platform and also uses Kerberos authentication to avoid software attacks. This proposed approach establishes file locality by clustering the related data based on their physical distance and effective matching with client applications. It supports efficient clustering and reduces communication cost in large-scale cloud computing applications.

Recent mishaps such as the missing MH370 aircraft and the sunk Korean Sewol ferry go to show that our technology in safety and security risk assessment still need a more integrated approach. Nuclear plant meltdown in the recent Fukushima accident is also a typical example of insufficient risk assessments. This work is a case study on how a unified security and safety risk assessment methodology may be applied to a High Pressure Core Flooder (HPCF) system in a nuclear power plant. Individual risk security or safety assessments may overlook the possible higher risk associated with such critical systems. The case study shows how the proposed method provides a more accurate risk assessment compared to individual assessments.

In the introduced approach on OSI layer 2, attacks carried out by already authenticated and participating nodes (insider threats) can be detected and prevented. Forbidden activities and manipulations in hard- and software, such as executing unknown binaries, loading additional kernel modules or even inserting unauthorized USB devices, are detected and result in an autonomous reaction of each network participant. The provided trust establishment and authentication protocol operates independently from upper protocol layers and is optimized for resource constrained machines. Well known concepts of backbone architectures can maintain the chain of trust between different kinds of network types. Each endpoint, forwarding and processing unit monitors the internal network independently and reports misbehaviours autonomously to a central instance in or outside of the trusted network.

We investigate how this paradigm differs from existing computing paradigms, such as grid computing and the conventional cloud computing paradigms. We show that incentives to adopt this paradigm are intuitive and natural, and security and trust guarantees provided by it are solid. We propose metrics for measuring the utility and advantage of this computing paradigm, and using real-world social graphs and structures of social traces; we investigate the potential of this paradigm for ordinary users. We study several design options and trade-offs, such as scheduling algorithms, centralization, and straggler handling, and show how they affect the utility of the paradigm. Interestingly, we conclude that whereas graphs known in the literature for high trust properties do not serve distributed trusted computing algorithms, such as Sybil defenses-for their weak algorithmic properties, such graphs are good candidates for our paradigm for their self-load-balancing features.

Among collaborative e-Learning drawbacks which are not completely solved, we have investigated information security requirements in on-line assessment (e-assessment). To the best of our knowledge, security requirements cannot be reached with technology alone, therefore, new models such as trustworthiness approaches can complete technological solutions and support e-assessment requirements for e-Learning. Although trustworthiness models can be defined and included as a service in e-assessment security frameworks, there are multiple factors related to trustworthiness which cannot be managed without normalization. Among these factors we discuss trustworthiness multiple sources, different data source formats, measure techniques and other trustworthiness factors such as rules, evolution or context. Hence, in this paper, we justify why trustworthiness normalization is needed and a normalized trustworthiness model is proposed by reviewing existing normalization procedures for trustworthy values applied to e-assessments. Eventually, we examine the potential of our normalized trustworthiness model in a real online collaborative learning course.

Services can in turn be composed with the help of these participants. However, the composite structure, the subjective interpretation of trust demand, and the opportunistic connectivity make service composition a challenging task in S-MSN. In this paper, we propose a novel approach to enable trustworthy service evaluation and invocation during the process of composition. By analyzing dependency relationships, our approach can decentralizedly evaluate the trust degree of each service based on a lattice-based trust model to prevent data from being transmitted to untrustworthy counterparts. Besides, service consumers and vendors are able to specify their global and local constraints on the trust degree of service components on demand for more effective composition. Finally, by introducing acquaintances to the neighbors iteratively, social participants form a trust-aware acquaintance graph to forward invocation messages.

Using Multi-Agent Systems (MAS) as a paradigm for an electronic institution framework enables both to simulate and facilitate the process of autonomous agents, as either enterprises or individual representatives, reaching joint agreements through automatic negotiation. In the heart of the MAS-based electronic institution framework, a Normative Environment provides monitoring capabilities and enforcement mechanisms influencing agents' behavior during joint activities. Moreover, it makes available relevant data that can be important for building up contextual-dependent agent's trust models which, consequently, also influence future possible negotiations leading to new and safer agreements. To support agents information generation, monitoring and fusion, we here present ANTE platform, a software MAS integrating Trust models with negotiation facilities and Normative environments, for the creation and monitoring of agent-based networks.

As MSNs are distributed public virtual social spaces, the available information may not be trustworthy to all. Therefore, mobile users are often at risk since they may not have any prior knowledge about others who are socially connected. To address this problem, trust inference plays a critical role for establishing social links between mobile users in MSNs. Taking into account the nonsemantical representation of trust between users of the existing trust models in social networks, this paper proposes a new fuzzy inference mechanism, namely MobiFuzzyTrust, for inferring trust semantically from one mobile user to another that may not be directly connected in the trust graph of MSNs. First, a mobile context including an intersection of prestige of users, location, time, and social context is constructed. Second, a mobile context aware trust model is devised to evaluate the trust value between two mobile users efficiently. Finally, the fuzzy linguistic technique is used to express the trust between two mobile users and enhance the human's understanding of trust. Real-world mobile dataset is adopted to evaluate the performance of the MobiFuzzyTrust inference mechanism. The experimental results demonstrate that MobiFuzzyTrust can efficiently infer trust with a high precision.

Indeed, the complex layered nature of service-based systems frequently leads to service failure and conflicting adaptation. To tackle this problem, we propose an ontology-based categorization of service behavior across all the functional layers. The proposed ontology provides support for cross-layer self-adaptation by facilitating reasoning about events to identify the real source of service failure, and reasoning about self-adaptation actions to check integrity and compatibility of self-adaptation with constraints imposed by each layer.

Haiying Shen; Guoxin Liu, "An Efficient and Trustworthy Resource Sharing Platform for Collaborative Cloud Computing," Parallel and Distributed Systems, IEEE Transactions on, vol.25, no.4, pp. 862, 875, April 2014. doi:10.1109/TPDS.2013.106 Abstract: Advancements in cloud computing are leading to a promising future for collaborative cloud computing (CCC), where globally-scattered distributed cloud resources belonging to different organizations or individuals (i.e., entities) are collectively used in a cooperative manner to provide services. Due to the autonomous features of entities in CCC, the issues of resource management and reputation management must be jointly addressed in order to ensure the successful deployment of CCC. However, these two issues have typically been addressed separately in previous research efforts, and simply combining the two systems generates double overhead. Also, previous resource and reputation management methods are not sufficiently efficient or effective. By providing a single reputation value for each node, the methods cannot reflect the reputation of a node in providing individual types of resources. By always selecting the highest-reputed nodes, the methods fail to exploit node reputation in resource selection to fully and fairly utilize resources in the system and to meet users' diverse QoS demands. We propose a CCC platform, called Harmony, which integrates resource management and reputation management in a harmonious manner. Harmony incorporates three key innovations: integrated multi-faceted resource/reputation management, multi-QoS-oriented resource selection, and price-assisted resource/reputation control. The trace data we collected from an online trading platform implies the importance of multi-faceted reputation and the drawbacks of highest-reputed node selection. Simulations and trace-driven experiments on the real-world PlanetLab testbed show that Harmony outperforms existing resource management and reputation management systems in terms of QoS, efficiency and effectiveness.

Johnson, L.; Choi Han-Lim; How, J.P., "Convergence Analysis of the Hybrid Information and Plan Consensus Algorithm," American Control Conference (ACC), 2014, pp. 3171, 3176, 4-6 June 2014. doi: 10.1109/ACC.2014.6859325 Abstract: This paper presents a rigorous analysis of the Hybrid Information and Plan Consensus (HIPC) Algorithm previously introduced in Ref. [1]. HIPC leverages the ideas of local plan consensus and implicit coordination to exploit the features of both paradigms. Prior work on HIPC has empirically shown that it reduces the convergence time and number of messages required for distributed task allocation algorithms. This paper further explores HIPC to rigorously prove convergence and provides a worst case on the time to convergence. This worst-case bound is no slower than a comparable plan consensus algorithm, Bid Warped CBBA [2], requiring two times the number of tasks times the network diameter iterations for convergence. Additionally, the analysis of convergence highlights why the performance of HIPC is significantly better than this on average. Convergence bounds of this type are essential creating trustworthy autonomy, and for guaranteeing performance when using these algorithms in the field.

Kouno, Kazuaki; Aikebaier, Ailixier; Enokido, Tomoya; Takizawa, Makoto, "Trustworthiness-Based Group Communication Protocols," Network-Based Information Systems (NBiS), 2014 17th International Conference on, pp.490,494, 10-12 Sept. 2014. doi: 10.1109/NBiS.2014.52 Abstract: In distributed applications, a group of multiple process are cooperating with each other by exchanging messages in underlying networks. A message sent by each process has to be delivered to every process in a group. In this paper, we discuss a protocol for reliably, efficiently transmitting messages to every operational process in a group. We assume that each process can send messages to only neighboring processes like wireless networks and scalable peer-to-peer (P2P) overlay networks. Here, a process sends a message to its neighboring processes and then each neighboring process forwards the message to its neighboring processes. In this paper, we propose a trustworthiness-based group communication protocol where only trustworthy neighboring processes forward messages. In order to reduce the number of messages, a trustworthy neighboring process is a process which can more reliably forward messages. We discuss how to obtain the trustworthiness of a process in networks and forward messages to every process through trustworthy processes. We discuss a reactive type of protocol to reliably deliver message to a destination process m a wireless network.
