Image Encryption Algorithm Based on Hyperchaotic System and DNA Coding

Aiming at the problems of large amount of data, strong correlation between adjacent pixels and high redundancy in the process of color image encryption, a color image encryption algorithm based on hyperchaotic system and DNA coding operation is proposed, which combines with the neural network to generate a better fusion random sequence as key stream, and uses DNA transformation rules and block encryption mechanism to realize image scrambling diffusion encryption in pixel level. The simulation results show that the encryption algorithm has high security integrity and strong anti-attack ability.
