Abstract

In this paper, we present several new constructions of differentially 4-uniform permutations over \F22m\F_{2^{2m}} by modifying the values of the inverse function on some subsets of \F22m\F_{2^{2m}}. The resulted differentially 4-uniform permutations have high nonlinearities and algebraic degrees, which provide more choices for the design of cryptographic substitution boxes.
