Visible to the public CAREER: The Theoretical Foundations of Symmetric Cryptography

Submitted by Stefano Tessaro on Fri, 10/06/2017 - 3:01pm

Cryptography is essential to ensure confidentiality and integrity of information. Due to their practicality, symmetric algorithms where the same secret key is used by the sender and the recipient underlie most practical deployments of cryptographic techniques. However, also as a result of this, symmetric cryptography suffers from an inherent tension between real world efficiency demands and provable security guarantees. This project investigates new technical advances aimed at narrowing the gap between provable security and the practical demands of symmetric cryptography.

Visible to the public CAREER: Secure OS Views for Modern Computing Platforms

Submitted by enck on Fri, 10/06/2017 - 2:58pm

The security architecture of consumer operating systems is currently undergoing a fundamental change. In platforms such as Android, iOS, and Windows 8, each application is a separate security principal that can own data. While this distinction is a vast improvement over traditional user-focused security architectures, sharing data between applications results in an unexpected loss of control of that data, potentially exposing security and privacy sensitive information.

Visible to the public CAREER: Re-thinking Electronic Design Automation Algorithms for Secure Outsourced Integrated Circuit Fabrication

Submitted by Siddharth Garg on Fri, 10/06/2017 - 2:56pm

Semiconductor chip fabrication is being increasingly outsourced to off-shore foundries. Outsourced fabrication reduces cost by leveraging economies-of-scale and ensures access to the most advanced manufacturing technology, but comes at the expense of trust. How can the chip designer trust that the off-shore (untrusted) foundry does not pirate its intellectual property (IP), or maliciously modify the integrated circuit (IC) by inserting a hardware Trojan in the chip? This project develops transformative new solutions for trustworthy chip fabrication at off-shore foundries.

Submitted by Meng Yu on Fri, 10/06/2017 - 2:49pm

Cloud computing offers many benefits to users, including increased availability and flexibility of resources, and efficiency of equipment. However, privacy concerns are becoming a major barrier to users transitioning to cloud computing. The privilege design of existing cloud platforms creates great challenges in ensuring the trustworthiness of cloud by granting too much power to the cloud administrators, who could launch serious insider attacks by abusing the administrative privileges.

Visible to the public CRII: SaTC: Camera-based mobile device end-user authentication

Submitted by Matthias Kirchner on Fri, 10/06/2017 - 2:42pm

Secure and useable end-user authentication is a major challenge in a modern society that allocates and relocates more and more resources online. As many users nowadays carry a mobile device (e.g., a smartphone), authentication approaches beyond the often-criticized traditional password leverage auxiliary information that can be received by, displayed on, computed by or sent from these omnipresent personal companions.

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 TTP: Small: Collaborative: Defending Against Website Fingerprinting in Tor

Submitted by Matthew Wright on Fri, 10/06/2017 - 2:27pm

The more people use the Internet, the more they risk sharing information they don't want other people to know. Tor is a technology that every day helps millions of people protect their privacy online. Tor users -- ranging from ordinary citizens to companies with valuable intellectual property -- gain protection for the content of their online messages and activities, as well as whom they interact with and when. For the most part, Tor is very secure. However, it has a known vulnerability to an attack called website fingerprinting.
