General Diffusion Analysis: How to Find Optimal Permutations for Generalized Type-II Feistel Schemes

Type-II Generalized Feistel Schemes are one of the most popular versions of Generalized Feistel Schemes. Their round function consists in applying a classical Feistel transformation to p sub-blocks of two consecutive words and then shifting the k = 2p words cyclically. The low implementation costs...
