关于$c$ -Boomerang均匀性和完全非线性的研究

Investigations on $c$-Boomerang Uniformity and Perfect Nonlinearity

Pantelimon Stanica

摘要:

本文在~ \cite{EFRST20}中定义了一个新的乘性$c$ -微分,以及相应的$c$ -微分一致性,并利用这个新概念刻画了已知的完全非线性函数,以及逆函数的特征.这项工作在~ \cite{RS20}中继续进行,研究了某些进一步APN函数的$c$ -微分一致性。在这里,我们将这个概念扩展到由Cid等人在Eurocrypt '18上介绍的回飞棒均匀性。\cite{Cid18},计算分组密码的S盒,并在完全非线性和相关函数的背景下研究它。

英文摘要:

We defined in~\cite{EFRST20} a new multiplicative $c$-differential, and the corresponding $c$-differential uniformity and we characterized the known perfect nonlinear functions with respect to this new concept, as well as the inverse in any characteristic. The work was continued in~\cite{RS20}, investigating the $c$-differential uniformity for some further APN functions. Here, we extend the concept to the boomerang uniformity, introduced at Eurocrypt '18 by Cid et al.~\cite{Cid18}, to evaluate S-boxes of block ciphers, and investigate it in the context of perfect nonlinearity and related functions.
