Abstract

We suggest, in a methodological manner, the use of Wavelet transforms to improve side channel analysis (SCA). The proposed applications are involved in several side channel analysis aspects: storage of traces, patterns detection and noise filtering. We show that all these aspects are useful to improve evaluation of information leakages from embedded devices. In particular, we show how wavelets favour practical secret key recovery.
