Visible to the public TWC: Small: Communication under Adversarial Attacks in Complex Networks - Fundamental Limits and Secure Coding Strategies

Today's world is highly dependent on the integrity of communication systems as the Internet, WiFi, or cellular networks. As networks become more pervasive, they are increasingly being used for communication and storage of critical as well as sensitive data and therefore impose more stringent demands on reliability and security, which must be maintained even under extreme settings such as partial power failures, natural disasters, or, most importantly, adversarial attacks.

Visible to the public TWC: Small: Towards Stealth Networks: Fundamental Limits and Algorithms for Stealth Communications

The widespread development of communication networks has profoundly transformed our society, resulting in a significant increase in productivity and efficiency. However, the benefits of this increased connectivity are today also counterbalanced by the ease with which malicious individuals can interfere or tamper with sensitive data and information. The past decade has thus witnessed a growing concern for the issues of privacy, confidentiality, and integrity of communications.

Visible to the public TWC TTP: Small: Collaborative: Privacy-Preserving Data Collection and Access for IEEE 802.11s-Based Smart Grid Applications

The modernized Smart Grid (SG) is expected to enable several new applications such as dynamic pricing, demand response and fraud detection; however, collection of such fine-grained data raises privacy issues. This project aims to design and implement several novel mechanisms for securing data collection and communication in SG Advanced Metering Infrastructure applications while preserving user privacy when the data are to be accessed.

Visible to the public TWC: Medium: Secure and Resilient Vehicular Platooning

The goal of the project is to provide a secure foundation for a transportation system that increasingly relies on the cooperation, connectedness, and automation of vehicles to achieve increases in safety, efficiency, and capacity. The financial losses attributable to congestion in America's transportation infrastructure are more than $1 trillion annually and the parallel loss of life in vehicle collisions is 40,000 deaths per year.

Visible to the public CAREER: EASE: Enhancing the Security of Pervasive Wireless Networks by Exploiting Location

Wireless systems have become an inseparable part of our social fabric, which allow users to move around and access the services from different locations while on the move. However, wireless security is often cited as a major technical barrier that must be overcome before widespread adoption of mobile services can occur. Traditional approaches have focused on addressing security threats on a case-by-case basis in an ad-hoc manner as new and specialized threats are uncovered.

Visible to the public EAGER: Collaborative Research: Towards Understanding Smartphone User Privacy: Implication, Derivation, and Protection

This project aims to address privacy concerns of smartphone users. In particular, it investigates how the usages of the smartphone applications (apps) may reshape users' privacy perceptions and what is the implication of such reshaping. There has been recent work that investigates privacy leakage and potential defense mechanisms. However, so far there is only limited understanding on the consequences of such privacy losses, especially when large amount of privacy information leaked from smartphone users across many apps.

Visible to the public TWC: Small: Collaborative: Multipath TCP Side Channel Vulnerabilities and Defenses

The objective of this project is to understand and strengthen the security of Multipath TCP (MPTCP) - an IETF standardized suite of TCP extensions that allow one MPTCP connection, consisting of multiple sub-connections between two hosts, to use multiple paths simultaneously. Even though MPTCP has been gaining momentum in being widely deployed, its security is yet to be well understood. The project is expected to raise awareness of MPTCP security and ultimately yield a foundation for MPTCP security.

Visible to the public TWC: TTP Option: Small: Differential Introspective Side Channels --- Discovery, Analysis, and Defense

Side channels in the security domain are known to be challenging to discover and eliminate systematically. Nevertheless, they can lead to a variety of stealthy attacks seriously compromising cybersecurity. This work focuses on an important class of side channels that are fundamental to the operations of networked systems.

Visible to the public EDU: Collaborative: Enhancing Pervasive and Mobile Computing Security Education With Research Integration

This project will help address the shortage of highly-skilled Cybersecurity professionals by bringing research results on pervasive and mobile computing security into education and by integrating them into existing Cybersecurity curricula. Although the research community is making progress towards effective solutions in mitigating security and privacy threats in pervasive computing, it still needs to find its way to university courses across the nation, especially, in the undergraduate curriculum.

Visible to the public TWC: Small: Techniques and Tools for Enforcing Proximity-based Policies in Wireless Systems

As wireless technologies become more pervasive, it becomes increasingly important for devices to authenticate the locations of other devices. For example, patients with implantable medical devices (IMDs) may reasonably expect that any device used to control their IMD would have to be within arm's reach, to help prevent unauthorized access to their device. In other words, IMDs should enforce policies based on the proximity, and in general the location, of wirelessly connected devices.
