Abstract

A new symmetric matrix power cipher is presented. The main component of this cipher is the key dependent S-box based on the matrix power function (MPF). We give the details of the cipher and explain how MPF can be used in multiple rounds. The matrix power cipher due to its special algebraic structure can be highly parallelized and each round can be separated up to m2 distinct threads, where m is an order of square matrices used in the cipher. A security analysis and main security parameters are also provided.
