Abstract:

Functions with low differential uniformity have wide applications in cryptography. In this paper, by using the quadratic character of F-pn*, we further investigate the (-1)-differential uniformity of these functions in odd characteristic: (1) f(1)(x) = x(d), where d = - p(n)-1/2 + p(k) + 1, n and k are two positive integers satisfying n/gcd(n,k) is odd; (2) f(2)(x) = (x(pm) - x)(pn-1/2) (+1) + x + x(pm), where n = 3m; (3) f(3)(x) = (x(3m) - x) 3(n-1/2 +1) + (x(3m) - x) 3(n-1/2) +3(m) + x, where n = 3m. The results show that the upper bounds on the (-1)-differential uniformity of the power function f(1)(x) are derived. Furthermore, we determine the (-1) -differential uniformity of two classes of permutation polynomials f(2)(x) and f(3)(x) over F-pn and F-3n, respectively. Specifically, a class of permutation polynomial f(3)(x) that is of P-1N or AP(-1)N function over F-3n is obtained.
