Abstract
Among the encryption technologies with chaos theory, cellular automatons with feature of discrete dynamical system and easy implementation, have unique advantages. Based on the Elementary and Life-liked cellular automaton, a new image encryption scheme is proposed in this paper. In this scheme, encryption equations are space distributed according to a chaotic map, and pixels in different areas might be encrypted with distinct encryption kernels. This fashion can provide additional security for the whole system. The simulation results and security analysis demonstrate the effectiveness and advantages of the proposed cryptosystem.
