In this paper we consider the generalized Diffie-Hellman key to the matrix case, the formation of two-dimensional key algorithms and their implementation on the basis of matrix models. Generated by key algorithm used for matrix models and algorithms kriptopreobrazovaniya images. The procedures of quick calculations based on bit-slice design matrix and elementwise fixed-matrix power by module tailored to image and that can be adapted to the parallel hardware implementations. The results of the simulation of a matrix-key image dimensions of 128 × 128 elements in a software environment Mathcad Professional.
