This paper introduces QARMA, a new family of lightweight tweakable block ciphers targeted
at applications such as memory encryption, the generation of very short tags for hardware …

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 …

We study the synthesis of small functions used as building blocks in lightweight
cryptographic designs in terms of hardware implementations. This phase most notably …

Recently a lot of attention is paid to the search for efficiently implementable MDS matrices for
lightweight symmetric primitives. Most previous work concentrated on locally optimizing the …

MDS matrices are an important element for the design of block ciphers such as the AES. In
recent years, there has been a lot of work on the construction of MDS matrices with a low …

At the FSE conference of ToSC 2018, Kranz et al. presented their results on shortest linear
programs for the linear layers of several well known block ciphers in literature. Shortest …

MDS matrices are important building blocks providing diffusion functionality for the design of
many symmetric-key primitives. In recent years, continuous efforts are made on the …

This article presents a new hybrid method (combining search based methods and direct
construction methods) to generate all 4× 4 involutory maximum distance separable (MDS) …

Lightweight cryptography features a small footprint and/or low computational complexity.
Low-cost implementations of linear layers usually play an important role in lightweight …

In this paper, we propose an efficient method to find lightweight involutory MDS matrices. To
obtain involutory matrices, we give a necessary and sufficient condition for judging the …
