关于$c$ -(几乎)完全非线性函数的构造与(不)存在性

On construction and (non)existence of $c$-(almost) perfect nonlinear functions

Daniele Bartoli, Marco Calderini

摘要:

具有低微分一致性的函数在密码学中有相关的应用。近年来,具有低$c$ -微分一致性的函数引起了人们的广泛关注。特别地,已经研究了所谓的APcN和PcN函数(APN和PN函数的推广)。在这里,我们通过二次多项式以及不存在的结果提供了这样的功能的特征。

英文摘要:

Functions with low differential uniformity have relevant applications in cryptography. Recently, functions with low $c$-differential uniformity attracted lots of attention. In particular, so-called APcN and PcN functions (generalization of APN and PN functions) have been investigated. Here, we provide a characterization of such functions via quadratic polynomials as well as non-existence results.
