%X 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.
