Side-Channel Attack Resistance — April 2022

PI(s): Heechul Yun

HARD PROBLEM(S) ADDRESSED: Resilient Architectures

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:

In this quarter, we have made the following progress.

• We have continued to explore various microarchitectural attack and defense techniques on Intel and ARM platforms.
• Our paper, " Denial-of-Service Attacks on Shared Resources in Intel's Integrated CPU-GPU Platforms," was accepted for publication at IEEE ISORC 2022. This work demonstrates the DoS attack vulnerability of two generations of Intel processors with iGPU and the effectiveness (and limitations) of hardware based mitigation techniques.
