摘要:

本文通过修改逆函数在$\text{F}_{2^{2m}}$某些子集上的取值,提出了若干种$\text{F}_{2^{2m}}$上差分4一致置换的新构造方法。所得的差分4一致置换具有高非线性度和高代数次数,为密码学S盒(代换盒)的设计提供了更多选择。

英文摘要:

In this paper, we present several new constructions of differentially 4-uniform permutations over $\F_{2^{2m}}$ by modifying the values of the inverse function on some subsets of $\F_{2^{2m}}$. The resulted differentially 4-uniform permutations have high nonlinearities and algebraic degrees, which provide more choices for the design of cryptographic substitution boxes.
