摘要
In this paper, two infinite classes of quadratic differentially p-uniform binomials over (n is divisible by 4 or 3) are constructed from known perfect nonlinear binomials. In particular, for , such functions are ternary differentially 3-uniform functions which are not CCZ-equivalent to known ones. In addition, two classes of permutation monomials with low differential uniformity over finite fields of odd characteristic are also provided.
