"WebEncrypting 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 propose a new … " - Cachebleed

In this work we present CacheBleed—the ﬁrst side-channel attack to exploit cache-bank conﬂicts. In Section 3, we describe how CacheBleed creates contention on a cache bank and measures the timing variations due to conﬂicts. We use CacheBleed to attack the scatter-gather implementation of RSA in the current version of OpenSSL (1.0.2f). After WebThe CacheBleed attack targets cache bank conflicts and thereby invalidates the assumption that microarchitectural side-channel adversaries can only observe memory with cache line granularity.
