Constructing New Piecewise Differentially 4-Uniform Permutations from Known APN Functions
Guangkui Xu, Xiwang Cao · International Journal of Foundations of Computer Science · 2015
A method for constructing piecewise differentially 4-uniform permutations has been recently introduced by Zha, Hu and Sun. By using this method, we provide two new infinite families of differentially 4-uniform permutations from the known APN functions. The CCZ inequivalence between these constructed functions and the known differentially 4-uniform permutations are also investigated by computation.
