Differentially 4-Uniform Permutations with the Best Known Nonlinearity from Butterflies

Differentially 4-Uniform Permutations with the Best Known Nonlinearity from Butterflies

Many block ciphers use permutations defined over the finite field F22k with low differential uniformity, high nonlinearity, and high algebraic degree to provide confusion. Due to the lack of knowledge about the existence of almost perfect nonlinear (APN) permutations over F22k, which have lowest pos...
