ShiftRows Alternatives for AES-like Ciphers and Optimal Cell Permutations for Midori and Skinny

2018 · IACR Transactions on Symmetric Cryptology

We study possible alternatives for ShiftRows to be used as cell permutations in AES-like ciphers. As observed during the design process of the block cipher Midori, when using a matrix with a non-optimal branch number …

Weighted Reed-Solomon convolutional codes

2020 · arXiv (Cornell University)

In this paper we present a concrete algebraic construction of a novel class of convolutional codes. These codes are built upon generalized Vandermonde matrices and therefore can be seen as a natural extension of Reed-Solomon …
