Bivariate attacks and confusion coefficients

Sylvain Guilley and Liran Lerman

Abstract

We solve the problem of finding the success rate of an optimal side-channel attack targeting at once the first and the last round of a block cipher. We relate the results to the properties of the direct and inverse substitution boxes (when they are bijective), in terms of confusion coefficients.
