Abstract:

Functions with low differential uniformity have wide applications in cryptography. In this paper, by using the quadratic character of Fpn∗ , we further investigate the (- 1) -differential uniformity of these functions in odd characteristic: (1) f1(x) = xd , where d=-pn-12+pk+1 , n and k are two positive integers satisfying ngcd(n,k) is odd; (2) f2(x)=(xpm-x)pn-12+1+x+xpm , where n= 3 m ; (3) f3(x)=(x3m-x)3n-12+1+(x3m-x)3n-12+3m+x , where n= 3 m . The results show that the upper bounds on the (- 1) -differential uniformity of the power function f1(x) are derived. Furthermore, we determine the (- 1) -differential uniformity of two classes of permutation polynomials f2(x) and f3(x) over Fpn and F3n , respectively. Specifically, a class of permutation polynomial f3(x) that is of P - 1 N or AP - 1 N function over F3n is obtained. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
