              Abstract
              We present several new constructions of differentially 4uniform permutations over mathbbF 22m   by modifying the values of the inverse function on some subsets of mathbbF 22m   The resulted differentially 4uniform permutations have high nonlinearities and algebraic degrees which provide more choices for the design of crytographic substitution boxes
