我们引入了两个新的无限 APN 函数族,一个在 22k 阶的域上,其中 k 不能被 2 整除,另一个在 23k 阶的域上,因为 k 不能被 3 整除。第一个族中的多项式有 3 到 k+2 项,第二族的多项式有 3 项。
We introduce two new infinite families of APN functions, one on fields of order 22kfor k not divisible by 2, and the other on fields of order 23kfor k not divisible by 3. The polynomials in the first family have between three and k+2 terms, the second family's polynomials have three terms.
