This paper proposes a chaos-based image encryption scheme where one 2D tent map with two control parameters is

utilized to generate chaotic orbits applied to scramble the pixel positions while one coupled map lattice is employed to

yield random gray value sequences to change the gray values so as to enhance the security. Experimental results are carried

out with detailed analysis to demonstrate that the proposed image encryption scheme possesses large key space to resist

brute-force attack and possesses good statistical properties to frustrate statistical analysis attacks. Experiments are also

performed to illustrate the robustness against malicious attacks like cropping, noising, JPEG compression
