Abstract:

Permutation polynomials with low boomerang uniformity have wide applications in cryptography. In this paper, by utilizing the Weil sums technique and solving some certain equations over 2n, we determine the boomerang uniformity of these permutation polynomials: (1) f1(x) = (x2m + x + δ)22m+1 + x, where n = 3m, δ 2n with Trmn(δ) = 1; (2) f2(x) = (x2m + x + δ)22m-1+22m-1+ x, where n = 3m, δ 2n with Trmn(δ) = 0; (3) f3(x) = (x2m + x + δ)23m-1+2m-1 + x, where n = 3m, δ 2n with Trmn(δ) = 0. The results show that the boomerang uniformity of f1(x), f2(x) and f3(x) can attain 2n. © 2025 World Scientific Publishing Company.
