Hardware

The project explores building support for malware detection in hardware. Malware detection is challenging and resource intensive, as the number and sophistication of malware increases. The resource requirements for malware detection limit its use in practice, leaving malware unchecked on many systems. We use a low level hardware detector to identify malware as a computational anomaly using low level features such as hardware events, instruction mixes and memory address patterns.

Applications that run on billions of mobile devices backed by enormous datacenters hold the promise of personal, always-on healthcare; of intelligent vehicles and homes; and thus of a healthier, more efficient society. It is imperative to make such applications secure by protecting their integrity and keeping their data confidential. However, malicious programs (``malware'') today can subvert the best software-level defenses by impersonating benign processes on mobile devices or by attacking victim processes through the hardware on shared datacenter servers.

Hardware authentication is one of the critical needs in the emerging discipline of design for assurance and design for security. It is concerned with establishing the authenticity and provenance of Integrated Circuits (ICs) reliably and inexpensively at any point in a chip's life-time. Physical unclonable functions (PUFs) have significant promise as basic primitives for authentication since they can serve as intrinsically-generated hardware roots-of-trust within specific authentication protocols.

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.

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.
