Different types of implementation attacks, like those based on side channel leakage and active fault injection, are often considered as separate threats. Countermeasures are, there...
In this paper we present two attacks that exploit cache events, which are visible in some side channel, to derive a secret key used in an implementation of AES. The first is an imp...
—Caches ideally should have low miss rates and short access times, and should be power efficient at the same time. Such design goals are often contradictory in practice. Recent f...
