On the Direct Construction of MDS and Near-MDS Matrices. (arXiv:2306.12848v1 [cs.IT])
cs.CR updates on arXiv.org arxiv.org
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 have been proposed for designing MDS matrices,
including search and direct methods. While exhaustive search is suitable for
small order MDS matrices, direct constructions are preferred for larger orders
due to the vast search space involved. In the literature, there has been
extensive research on the direct construction of MDS matrices using both
