ePrint Report: SCARF: A Low-Latency Block Cipher for Secure Cache-Randomization

Federico Canale, Tim Güneysu, Gregor Leander, Jan Thoma, Yosuke Todo, Rei Ueno

Randomized cache architectures have proven to significantly
increase the complexity of contention-based cache side channel attacks
and therefore pre\-sent an important building block for side channel secure
microarchitectures. By
randomizing the address-to-cache-index mapping, attackers can
no longer trivially construct minimal eviction sets which are
fundamental for contention-based cache attacks. At the same time,
randomized caches maintain the flexibility …
