Abstract:

A survey for MDS matrices design strategy was made.Design strategies and the key issues during the de-sign were elaborated,and many aspects such as principle and implementation mechanisms of some typical and common construction of MDS matrices were analyzed and discussed.In addition,the research results on lightweight MDS matrices in recent years were investigated.

Key words: block cipher, optimal diffusion layer, branch number, MDS matrix, linear transformation
