Shift-Invariant Permutations with Polynomial Composition: Construction and Algebraic Structure

Shift-invariant permutations of $\mathbb F_2^n$ are particularly attractive in symmetric cryptography because of their regularity and implementation efficiency. Constructing such permutations with an explicit algebraic structure remains a challenging problem. In this paper, we study a family of shift-invariant transfor...

A Class of Shift-Invariant Permutations and Their Algebraic Structure

Shift-invariant permutations of $\mathbb F_2^n$ are attractive in symmetric cryptography because of their regularity and implementation efficiency. Constructing such permutations with an explicit algebraic structure remains a challenging problem. In this paper, we study a family of shift-invariant transformations of $\...
