Since multimedia images are widely used for Internet communications, the need to securely transmit these images over a network has become an essential part of the field of data security. In this paper, we propose an image encryption algorithm based on cellular automata that can implement hardware and perform hardware-friendly operations. In order to generate a more effective key sequence than 1-D 90/150 MLCA, we propose a method for synthesizing 1- D symmetric 5-neighbor MLCAs. In addition, we design a 1-D symmetric 5-neighbor MLCA-based color image encryption system synthesized by the proposed method. The safety of the proposed cryptosystem is verified through statistical experiments and analysis.
