Protecting Cache States Against Both Speculative Execution Attacks and Side-channel Attacks. (arXiv:2302.00732v1 [cs.CR])

Cache side-channel attacks and speculative execution attacks that leak
information through cache states are stealthy and dangerous attacks on hardware
that must be mitigated. Unfortunately, defenses proposed for cache side-channel
attacks do not mitigate all cache-based speculative execution attacks and vice
versa. Since both classes of attacks must be addressed, we propose
comprehensive cache architectures to do this.

We show a framework to analyze the security of a secure cache. We identify
same-domain speculative execution attacks, and show they evade …
