我们在 GF(2n) 上提出了无限族四项式 APN 函数,其中可被 3 整除,但不能被 9 整除。该族包含通过将某些系数设置为 0 获得的不等价函数。我们还讨论了不等价证明(通过计算),表明这些函数是新函数。
We present an infinite family of quadrinomial APN functions onGF(2n) wherenis divisible by 3 but not 9. The family contains inequivalent functions, obtained by setting some coefficients equal to 0. We also discuss the inequivalence proof (by computation) which shows that these functions are new.
