Abstract
This paper combines a four-dimensional chaotic system with DNA technology to design a color image encryption algorithm. The algorithm converts each pixel value into two 4-bit binary for WSSM scrambling. The proposed 4D chaotic system is used to generate four chaotic sequences to determine the rules of DNA encoding, decoding and calculation. Finally, the three matrices of R, G, and B are divided into blocks and scrambled. Security analysis is carried out, including histogram, key sensitivity, entropy, correlation, anti-differential attack, anti-noise attack, occlusion attack and other aspects. All experimental results show that the proposed image encryption algorithm can effectively resist various attacks.
