弱APN函数的进一步研究
Further Study on Weakly APN Functions
研究了弱APN函数, 给出了弱APN函数存在的一个必要条件, 并提出了弱APN函数的两个判定准则. 运用所提出的准则对一些已知4-差分函数进行了讨论, 得到了几类具体的弱APN函数. 此外, 还研究了某些弱APN置换的性质.
In this paper, weakly APN functions are investigated and a necessary condition of weakly APN functions is proposed. Based on the proposed condition, two criteria are established to judge whether a differentially
