Title:
Generalized Polynomial Decomposition for S-boxes with Application to Side-Channel Countermeasures
Authors: Dahmun Goudarzi, Matthieu Rivain, Damien Vergnaud, Srinivas Vivek
Abstract:Masking is a widespread countermeasure to protect implementations of block-ciphers against side-channel attacks. Several masking schemes have been proposed in the literature that rely on the efficient decomposition of the underlying s-box(es). We propose a generalized decomposition method for s-boxes that encompasses several previously proposed methods while providing new trade-offs. It allows to evaluate n\lambda-bit to m\lambda-bit s-boxes for any integers n,m,\lambda \geq 1 by seeing it a sequence of m n-variate polynomials over \mathbb{F_{2^\lambda}} and by trying to minimize the number of multiplications over \mathbb{F_{2^\lambda}}.
