In implementing cryptographic algorithms on limited devices such as smart cards, speed and memory optimization had always been a challenge. With the advent of side channel attacks,...
Abstract. Since the announcement of the Differential Power Analysis (DPA) by Paul Kocher and al., several countermeasures were proposed in order to protect software implementations...
Abstract. Protecting an implementation against Side Channel Analysis for Reverse Engineering (SCARE) attacks is a great challenge and we address this challenge by presenting a fir...
It is believed that masking is an effective countermeasure against power analysis attacks: before a certain operation involving a key is performed in a cryptographic chip, the inpu...
Abstract. ESSENCE is a family of cryptographic hash functions, accepted to the first round of NIST's SHA-3 competition. This paper presents the first known attacks on ESSENCE....
