A matrix is MDS or super-regular if and only if every square submatrices of it are
nonsingular. MDS matrices provide perfect diffusion in block ciphers and hash functions. In …

In this article, we present WARP, a lightweight 128-bit block cipher with a 128-bit key. It aims
at small-footprint circuit in the field of 128-bit block ciphers, possibly for a unified encryption …

The optimal branch number of MDS matrices makes them a preferred choice for designing
diffusion layers in many block ciphers and hash functions. Consequently, various methods …

Many block ciphers and hash functions use MDS matrices because of their optimal branch
number. On the other hand, MDS matrices generally have a high implementation cost, which …

Recursive MDS matrices are used for the design of linear diffusion layers in lightweight
cryptographic applications. Most of the works on the construction of recursive MDS matrices …

SPN block ciphers are widely used in various fields today. Research on enhancing the
