Abstract
AbstractMDS diffusion layers are critical components in the design of symmetric ciphers.In this paper, after introducing some new algebraic structures, we provide new MDS matrices over special types of R-modules.With the help of the proposed methodology, we have more flexibility in designing software-oriented diffusion layers.Most notably, we construct randomized and/or nonlinear MDS diffusion layers, based upon the presented theoretical results, and discuss the resistance of the presented diffusion layers against various kinds of cryptanalysis, compared with classical linear diffusion layers.
