The traditional image encryption methods have some problems, such as poor security and inefficient encryption. This paper proposes a new image encryption method based on 3D Arnold-oriented elementary cellular automata. The new image encryption method first uses 3D Arnold to scramble pixel positions. Then, the elementary cellular automata based on quad-tree decomposition is used to further confuse the scrambled images at the specific level to obtain ciphertext images. The experiment results show that this new method can achieve good encryption effect with fewer iteration times and has strong sensitivity to plaintext and key. It also can effectively resist differential attack.
