New Cross-Core Cache-Agnostic and Prefetcher-based Side-Channels and Covert-Channels
Yun Chen, Ali Hajiabadi, Lingfeng Pei +1
In this paper, we reveal the existence of a new class of prefetcher, the XPT prefetcher, in the modern Intel processors which has never been officially documented. It speculatively…
Leaking Control Flow Information via the Hardware Prefetcher
Yun Chen, Lingfeng Pei, Trevor E. Carlson
Modern processor designs use a variety of microarchitectural methods to achieve high performance. Unfortunately, new side-channels have often been uncovered that exploit these enha…
Mitigating Power Attacks through Fine-Grained Instruction Reordering
Yun Chen, Ali Hajiabadi, Romain Poussier +3
Side-channel attacks are a security exploit that take advantage of information leakage. They use measurement and analysis of physical parameters to reverse engineer and extract sec…
