%X In this paper, an image encryption algorithm based on the coupled digital chaotic map is proposed. Firstly, Grey substitution is designed via the key stream using the coupled chaotic , then use standard chaotic map to construct permutation pixels scheme. The algorithm comprises permutation and grey value substitution. Through experimental tests are carried out with detailed analysis, demonstrating the high security and fast encryption speed of the new scheme.
