Block ciphers are one of the most important building blocks in cryptosystems.Modern block ciphers are often iterations of several rounds and each round consists of a confusion layer and a diffusion layer.Maximum distance separable(MDS)matrices can provide maximal diffusion,but MDS matrices are not sparse and have large description resulting costly implementations in hardware and software.
