Abstract
Masking is a well used and widely deployed countermeasure against side channel attacks, both in software and hardware. With masking comes at a great cost, search has focused on how to lower a performance penalty or find efficient masking implementation. In particular, our contribution is 2-fold: for software masking, we first find bitsliced implementations of Sbox with Multiplicative Complexity 4 and Multiplicative Depth 2, then adapt the common shares approach introduced by Coron et al. at CHES 2016 to make many cross-products
