- Abstract:
- In this paper, an image encryption scheme based on chaos system and genetic operation is proposed. First, the sha-3 algorithm is used to calculate the hash value of the plain-text image as the initial value of the chaotic system. Secondly, using the sensitivity of chaotic map to initial conditions and pseudo-randomness, the pseudo-random sequence generated by Logistic map generates hill matrix, and the image is scrambled and replaced. Thirdly, combining Duffing mapping and DNA coding technology, pixel selection, crossover and mutation can be realized at the level of genetic manipulation to complete pixel diffusion and scrambling, which significantly increases the difficulty of decoding the algorithm. Finally, the confusion and diffusion characteristics of the algorithm are further enhanced by bidirectional XOR with chaotic sequences. Experimental and security analysis results show that the algorithm is sensitive to key and can effectively resist statistical attack and differential attack. It has good security and application potential. The image encryption effect and performance are improved significantly.
