Paper Abstract

This paper discusses about ergodic matrices and related application about scrambling and encryption of digital images. First, we use ergodic matrices to realize the position permutation algorithms. In particular several novel methods of scrambling are proposed. Subsequently we analyze the isomorphism relationship between ergodic matrices and permutation group. By defining permutation symbol operation system of ergodic matrices, we construct a union form to express all existed permutation algorithms. Finally the images are encrypted using them. Preliminary results are satisfactory.
