Xishun Zhu, Xiangyong Zeng, Yuan Chen · International Journal of Foundations of Computer Science · 2015
Permutation polynomials with low differential uniformity are important candidate functions to design substitution boxes of block ciphers. In this paper, we investigate several classes of differential 4-uniform binomial and trinomial permutation polynomials over the finite field [Formula: see text] of [Formula: see text] elements.
