Abstract :
Side channel attacks exploit physical information leaked during the operation of a cryptographic or secured device, for example a smart card. This type of attacks is considered as a powerful technique for revealing confidential data such as secret keys of cryptographic algorithm. In our paper, first of all, we give a state-of-the art of different signal processing techniques used for side channel attacks. Then, we present our contributions with three signal processing techniques that permit to improve the performance of side channel attacks.
