Dynamic MDS Matrices for Substantial Cryptographic Strength
Muhammad Yasir Malik and Jong-Seon No
Abstract: Ciphers get their strength from the mathematical functions of
confusion and diffusion, also known as substitution and permutation. These were the basics of classical cryptography and they are still the basic part of modern ciphers. In block ciphers diffusion is achieved by the use of Maximum Distance Separable (MDS) matrices. In this paper we present some methods for constructing dynamic (and random) MDS matrices.
