New Directions in the Design of Binary Matrices for SPN Block Ciphers

Mahdi Sajadieh; Arash Mirzaei

Volume 15, Issue 3 , October 2023, , Pages 129-138


  The diffusion layer plays an important role in a block cipher. Some block ciphers, such as ARIA, Camellia, and Skinny use binary matrices as diffusion layers which can be efficiently implemented in hardware and software. In this paper, the goal is to propose some new binary matrices with suitable values ...  Read More

4n × 4n Diffusion Layers Based on Multiple 4 × 4 MDS Matrices

Mahdi Sajadieh; Arash Mirzaei

Volume 15, Issue 1 , January 2023, , Pages 111-124


  In terms of security, MDS matrices are one of the best choices for diffusion layer of block ciphers. However, as these matrices grow in size, their software implementation becomes a challenge. In this paper, to benefit from the properties of MDS matrices and avoid the mentioned challenge, we use 4*4 ...  Read More

Volume 11, Issue 1 , January 2019, , Pages 35-46


  Linear diffusion layer is an important part of lightweight block ciphers and hash functions. This paper presents an efficient class of lightweight 4x4 MDS matrices such that the implementation cost of them and their corresponding inverses are equal. The main target of the paper is hardware oriented cryptographic ...  Read More
