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 $F_{2^{n}}$

Yan-Ping Wang, WeiGuo Zhang, Zhengbang Zha

Block ciphers use S-boxes to create confusion in the cryptosystems. Such S-boxes are functions over $F_{2^{n}}$ . These functions should have low differential uniformity, h…
