AI总结:

该研究针对低$c$-差分一致性置换多项式构造的数学问题,利用Weil和与有限域方程分析方法,给出了几类满足条件的置换多项式,相关技术也具备独立研究意义。

摘要:

$c$-差分一致性的概念自提出以来便受到广泛关注~\uc7b1Ellingsen\uc7d5,近期有研究\uc7b1AMS22\uc7d5基于某些拟群中的差集,给出了完美$c$-非线性函数的刻画。除作为特定统计偏差度量的应用外,构造具有低$c$-差分一致性的函数(尤其是置换函数)是该领域一个有趣的数学问题,近年研究也重点聚焦于此方向。本文给出了几类具有低$c$-差分一致性的置换多项式,所采用的技术涉及处理各类Weil和以及分析有限域中的若干方程,我们认为这些技术本身也具有独立研究价值。

英文摘要:

The notion of $c$-differential uniformity has recently received a lot of attention since its proposal~\cite{Ellingsen}, and recently a characterization of perfect $c$-nonlinear functions in terms of difference sets in some quasigroups was obtained in~\cite{AMS22}. Independent of their applications as a measure for certain statistical biases, the construction of functions, especially permutations, with low $c$-differential uniformity is an interesting mathematical problem in this area, and recent work has focused heavily in this direction. We provide a few classes of permutation polynomials with low $c$-differential uniformity. The used technique involves handling various Weil sums, as well as analyzing some equations in finite fields, and we believe these can be of independent interest.
