: Differntial Power Attack (DPA) is one kind of Side Channel Attacks (SCAs). There are two phases in DPA attacks: sample collection and statistical analysis, which can be utilized ...
Prouff has introduced recently, at FSE 2005, the notion of transparency order of S-boxes. This new characteristic is related to the ability of an S-box, used in a cryptosystem in ...
For the power consumption model called Hamming weight model, we rewrite DPA attacks in terms of correlation coefficients between two Boolean functions. We exhibit properties of S-b...
There are many articles and patents on the masking of logic gates. However, the existing publications assume that a masked logic gate switches its output no more than once per cloc...
During the last years, several masking schemes for AES have been proposed to secure hardware implementations against DPA attacks. In order to investigate the effectiveness of thes...

Abstract. In the recent years, DPA attacks have been widely investigated. In particular, 2-nd order DPA have been improved and successfully applied to break many masked implementat...
