 This paper proposes a new color image encryption algorithm which combines multiple encoding techniques to improve both security and operational efficiency. It uses chaos sequences to generate a lookup table for base substitutions and then applies various encoding methods to increase randomness and strengthen security. Additionally, three-dimensional and six-directional diffusion is applied to the three channels of the color image allowing for faster processing while maintaining high security. Simulation results show that the algorithm has excellent encryption and decryption capabilities, a large key space, high key sensitivity, and strong security. Furthermore, it resists differential and statistical attacks, making it highly robust. This article was authored by Jia Lu, Hai Ping Cheng, Wei Yuan, and others.
