Differential Cache Trace Attack Against CLEFIA

Chester Rebeiro and Debdeep Mukhopadhyay

Abstract

The paper presents a differential cache trace attack against CLEFIA, a $128$ bit block cipher designed by Sony Corporation. The attack shows that such ciphers based on the generalized Feistel structures leak information of the secret key if the cache trace pattern is revealed to an adversary. The attack that we propose is a three staged attack and reveals the entire key with $2^{43}$ CLEFIA encryptions. The attack is simulated on an Intel Core 2 Duo Processor with a cache architecture with $32$ byte lines as a target platform.
