摘要
En 中文
Image encryption algorithm based on chaos has been widely used in various industries, but many image encryption algorithms based on low-dimensional chaos, resulting in the security of these encryption algorithms can not meet the requirements. In order to address the challenge, this paper proposes an image encryption algorithm based on 6D high-dimensional chaotic system and DNA encoding technique. First, the original image sequences is diffused and shuffled by several random chaos sequences. Second the generated sequences are diffused and shuffled by different chaos sequences on DNA level. At last, the different encoded sequences are combined into an encrypted image. The experimental results show that compared with the reference, the proposed algorithm has certain advantages in image entropy(value infinitely close to 8), pixel correlation and image complexity(key space larger than 2(300)), and also has good robustness against geometric and cut-off attacks.
