New results of -APN power functions over
Yan-Ping Wang, Zhengbang Zha
Partially APN functions attract researchers' particular interest recently. It plays an important role in studying APN functions. In this paper, based on the multivariate method and…
Two-to-one mappings and involutions without fixed points over $\bF_{2^n}$
Mu Yuan, Dabin Zheng, Yanping Wang
In this paper, two-to-one mappings and involutions without any fixed point on finite fields of even characteristic are investigated. First, we characterize a closed relationship be…
Low differentially uniform permutations from Dobbertin APN function over
Yan-Ping Wang, WeiGuo Zhang, Zhengbang Zha
Block ciphers use S-boxes to create confusion in the cryptosystems. Such S-boxes are functions over . These functions should have low differential uniformity, h…
Permutation polynomials and complete permutation polynomials over
Yanping Wang, WeiGuo Zhang, Daniele Bartoli +1
Motivated by many recent constructions of permutation polynomials over , we study permutation polynomials over in terms of their coefficients.…
More new classes of permutation trinomials over
Yanping Wang, WeiGuo Zhang, Zhengbang Zha
Permutation polynomials over finite fields have wide applications in many areas of science and engineering. In this paper, we present six new classes of permutation trinomials over…
