Abstract
Maximum Distance Separable (MDS) Matrices are used in block ciphers to achieve the maximum diffusion. Use of rhotrices increase the security as these are the representations of coupled matrices. We define Toeplitz rhotrix and construct the MDS rhotrices using Toeplitz rhotrices over finite fields.
