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, I 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.
