Visible to the public CAREER: A Pathway towards Channel Camouflage and Manipulation Techniques for Wireless Security

Submitted by Yao Liu on Fri, 10/06/2017 - 2:30pm

Wireless channel exhibits the spatial uncorrelation property, i.e., the characteristic of a wireless channel becomes uncorrelated every half carrier wavelength over distance. This property fertilizes an emerging research area that utilizes wireless channel characteristics to authenticate a wireless transmitter.

Visible to the public CAREER: Scaling Forensic Algorithms for Big Data and Adversarial Environments

Submitted by Matthew Stamm on Fri, 10/06/2017 - 2:19pm

Forged digital images or video can threaten reputations or impede criminal justice, due to falsified evidence. Over the past decade, researchers have developed a new class of security techniques known as 'multimedia forensics' to determine the origin and authenticity of multimedia information, such as potentially falsified images or videos. However, the proliferation of smartphones and the rise of social media have led to an overwhelming increase in the volume of multimedia information that must be forensically authenticated.

Visible to the public TWC: Phase: Medium: Collaborative Proposal: Understanding and Exploiting Parallelism in Deep Packet Inspection on Concurrent Architectures

Submitted by Somesh Jha on Fri, 10/06/2017 - 2:07pm

Deep packet inspection (DPI) is a crucial tool for protecting networks from emerging and sophisticated attacks. However, it is becoming increasingly difficult to implement DPI effectively due to the rising need for more complex analysis, combined with the relentless growth in the volume of network traffic that these systems must inspect. To address this challenge, future DPI technologies must exploit the power of emerging highly concurrent multi- and many-core platforms.

Visible to the public TWC: Small: Provably Enforcing Practical Multi-Layer Policies in Today's Extensible Software Platforms

Submitted by Jia Limin on Thu, 08/17/2017 - 10:36pm

A defining characteristic of modern personal computing is the trend towards extensible platforms (e.g., smartphones and tablets) that run a large number of specialized applications, many of uncertain quality or provenance. The common security mechanisms available on these platforms are application isolation and permission systems. Unfortunately, it has been repeatedly shown that these mechanisms fail to prevent a range of misbehaviors, including privilege-escalation attacks and information-flow leakage.

Visible to the public TWC: Medium: Collaborative: Re[DP]: Realistic Data Mining Under Differential Privacy

Submitted by Gerome Miklau on Thu, 08/17/2017 - 10:25pm

The collection and analysis of personal data about individuals has revolutionized information systems and fueled US and global economies. But privacy concerns regarding the use of such data loom large. Differential privacy has emerged as a gold standard for mathematically characterizing the privacy risks of algorithms using personal data. Yet, adoption of differentially private algorithms in industry or government agencies has been startlingly rare.

Visible to the public STARSS: Small: Side-Channel Analysis and Resiliency Targeting Accelerators

Submitted by David Kaeli on Thu, 08/17/2017 - 9:38pm

The design of social media interfaces greatly shapes how much, and when, people decide to reveal private information. For example, a designer can highlight a new system feature (e.g., your travel history displayed on a map) and show which friends are using this new addition. By making it seem as if sharing is the norm -- after all, your friends are doing it -- the designer signals to the end-user that he can and should participate and share information.
