WebApr 11, 2024 · Encrypting the mapping relationship between physical and cache addresses has been a promising technique to prevent conflict-based cache side-channel attacks. However, this method is not foolproof and the attackers can still build a side-channel despite the increased difficulty of finding the minimal eviction set. To address this issue, we … Weba) The cache memory simulator: The configurations of your cache simulator will be based on arguments given at the command line.
