不等价APN函数个数的一个下界
A lower bound on the number of inequivalent APN functions
摘要:
本文建立了具有$m$元素的有限域上不等价APN函数总数的一个下界,其中$2^{2m}$为偶数.我们通过证明Pott和第二作者引入的APN函数,依赖于三个参数$k$,$s$和$α$,对于参数$k$和$s$的不同选择是成对不等价的,从而得到了这个结果。此外,我们确定了这些APN函数的自同构群。
英文摘要:
In this paper, we establish a lower bound on the total number of inequivalent APN functions on the finite field with $2^{2m}$ elements, where $m$ is even. We obtain this result by proving that the APN functions introduced by Pott and the second author, that depend on three parameters $k$, $s$ and $α$, are pairwise inequivalent for distinct choices of the parameters $k$ and $s$. Moreover, we determine the automorphism group of these APN functions.
