Upper bounds of differential branch number of $$n$$ n -bit permutations

Abstract The differential branch number is a key parameter used to measure the diffusion ability of a permutation. It is of great significance to study the upper bound of the differential branch number of permutations. This paper analyses the existence problem of binary codes with a specified dimens...
