Abstract
For a function f:FqâFq on a finite field Fq, new measures-ambiguity A(f) and deficiency D(f) of f were raised by Panario et al. (2010, 2011) to judge non-injectivity and non-surjectivity of the difference functions Îaf:FqâFq(aâFqâ). In this paper, we determine the values of A(f) and D(f) for three differentially 4-uniform monomial permutations, i.e., inverse function, Gold function and Dobbertin function on F2n (2â£n).
