Beyond-Birthday-Bound Security for 4-round Linear Substitution-Permutation Networks

Beyond-Birthday-Bound Security for 4-round Linear Substitution-Permutation Networks

Recent works of Cogliati et al. (CRYPTO 2018) have initiated provable treatments of Substitution-Permutation Networks (SPNs), one of the most popular approach to construct modern blockciphers. Such theoretical SPN models may employ non-linear diffusion layers, which enables beyond-birthday-bound pr...
