Over the last decade, the analysis of how information flows through complex computer systems has been an important tool towards making such systems more secure and reliable. In this talk, Fred Chong will discuss three research thrusts in this area. First, the use of instruction-level information-flow tracking and virtual machines to address system-level security issues. For example, tracking the integrity of control flow information at the instruction level provides a general methodology for addressing many security exploits. Second, the use of gate-level information flow tracking to design secure hardware architectures. This extreme level of low-level hardware instrumentation or analysis reduces all information flows—whether explicit, implicit, or temporal—to the propagation of signals and allows for a uniform methodology for tracking all flows. Third, the use of mutual information measures to statically analyze reliability or information leakage requirements in next-generation systems. This ongoing work attempts to quantify information flows, not just detect them.

Fred Chong is the Director of Computer Engineering and a Professor of Computer Science at UCSB. He also leads the Green scale effort for energy-efficient computing. Chong received his Ph.D from MIT in 1996 and was a faculty member and Chancellor’s fellow at UC Davis from 1997 to 2005. He is a recipient of the NSF CAREER award, the DARPATech Most Significant Technical Achievement Award, and 5 best paper awards. His research interests include emerging technologies for computing, multicore and embedded architectures, computer security, and sustainable computing.
