On the lower bound of cost of mds matrices

Weband we present a lower bound on the period of these new nonlinear number generators. As a consequence, we present nonlinear recurrent sequences over 2 with periods which are multiples of the period of the corresponding sigma-LFSR’s. Keywords: Symmetric Cryptography, MDS Diffusion Layer, Group, Webnamely cyclic MDS matrices and propose new MDS matrices of this type. The presented matrices have lower implementation costs compared to what is presented up to now. In [10,15,16] diffusion layers in the form of a matrix power are examined. In this paper, we study decomposition of matrices from another viewpoint: we consider the product of ...
