This paper proposed a new image encryption scheme based on OCML and TD-ERCS map.In the proposed scheme,as a basic model of spatiotemporal chaotic system which exhibited chaotic properties both in time and in space,one-way coupled map lattice was adopted in permutation and the diffusion of gray value.The initial values and coupling coefficients were produced by a TD-ERCS map which had good random properties.The simple designed encryption scheme could work on digital image at any size,while its high security is proved by statistical experiments.
