HARD PROBLEM(S) ADDRESSED:

This project is developing OS and architecture techniques to defend against potential microarchitectural side-channel attacks on embedded computing platforms for safety-critical systems. The project covers the hardware problems of (1) resilient architectures (primary) and (2) security-metrics-driven evaluation, design, development and deployment.

PUBLIC ACCOMPLISHMENT HIGHLIGHTS:

  • We continue to develop effective micro-architectural attacks on commercial off-the-shelf computing platorms. We discovered a new contention based covert channel on Intel and AMD processors. We are evaluating viable attack scenarios with the covert channel. We also developed an improved denial-of-service attack methodology on shared cache in embedded multicore processors, which significantly outperform the state-of-the-art.
  • We continue to develop software and hardware level defense mechanisms to mitigate micro-architectural covert/side-channel attacks. We developed a holistic real-time scheduling framework in Linux that integrates a novel OS level scheduler and state-of-the-art resource isolation mechanisms to limit or eliminate micro-architectural attacks. We developed a light-weight bandwidth regulator IP on a RISC-V SoC.
