In order to improve security performance of the information stored in two-dimensional Code (Quick Response Code), a two-dimensional code encryption and decryption method based on Elementary Cellular Automata state rings is proposed in this paper. Cellular Automata can simulate complex phenomenon just using simple dynamical system. In addition, Cellular Automata and cryptography have a lot of similarities such as diffusivity and integrated chaos. Based on this feature, the method uses the Cellular Automata to encrypt and decrypt QR code binary image with the following parameters: the length is 8, the boundary condition is cyclic boundary condition and {0, 1} is the state space. The experimental results show that the method proposed in this paper has some advantages, such as high speed, good effect and high security.
