Abstract: Based on the ergodicity of the shifters (except for all zero-states) in m-sequence generator, in this paper a new m-sequence transform method is first proposed to apply to image position permutation. Combining this method with chaotic map, a novel image encryption approach is presented, and some simulating results are shown in this paper. Comparing with the existing encryption methods, the approach is not only of the characteristics of chaotic map with initial value sensitivity, parameter sensitivity and random sensitivity, but also of more larger secret key space. Thus the approach is more security than other encryption methods. -
