Remapped Cache Layout: Thwarting Cache-Based Side-Channel Attacks with a Hardware Defense. (arXiv:2211.06056v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
As cache-based side-channel attacks become serious security problems, various
defenses have been proposed and deployed in both software and hardware.
Consequently, cache-based side-channel attacks on processes co-residing on the
same core are becoming extremely difficult. Most of recent attacks then shift
their focus to the last-level cache (LLC). Although cache partitioning is
currently the most promising defense against the attacks abusing LLC, it is
ineffective in thwarting the side-channel attacks that automatically create
eviction sets or bypass the user address …
