Side-Channel Attack Resistance—2022Q2

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 develop various microarchitectural attack and defense techniques on Intel and ARM platforms
• Our paper, "A Closer Look at Intel Resource Director Technology (RDT)," was accepted and published at RTNS 2022. This work shows generational differences in Intel's RDT feature over two generations of Intel's processor designs.
• We open-sourced the attack code and test scripts used in our IOSRC paper.

COMMUNITY ENGAGEMENTS:

• Dr. Yun served as the program chair of RTAS'22, which took place virtually in May. RTAS is a premier conference in real-time embedded systems.

EDUCATIONAL ADVANCES:

• Dr. Yun developed a summer camp program on autonomous RC cars (based on our DeepPicar platform) for rural high-school students.
