We describe several software side-channel attacks based on inter-process leakage through the state of the CPU's memory cache. This leakage reveals memory access patterns, whic...

This paper presents a new attack against a software implementation of the Advanced Encryption Standard. The attack aims at flushing elements of the SBOX from the cache, thus indu...
Cache attacks on implementations of cryptographic algorithms have turned out to be very powerful. Progress in processor design, e.g., like hyperthreading, requires to adapt models ...
AVR XMEGA is the recent general-purpose 8-bit microcontroller from Atmel featuring symmetric crypto engines. We analyze the resistance of XMEGA crypto engines to side channel atta...
