This paper proposes an image encryption algorithm based on roulette jump selection chaotic system and alienated image library transformation. The algorithm obtains the fitness of each system from the plain image. Run the roulette algorithm to choose different chaotic systems according to their fitness, and the roulette algorithm is also used for parameter control, thus effectively reduces the dynamic degradation of chaotic systems. This paper first proposes an alienated image library transformation, which operates the plain image and multiple images in the agreed image library, thereby greatly improving the security of encryption. In the scrambling diffusion, synchronous scrambling diffusion is used. The pseudo-random sequence is sorted as a row and column index, and the image is synchronously scrambled and diffused by a pair of row and column mapping arrays. Through the experimental results and security analysis, the algorithm has very good security and can resist various attacks.

基于轮盘级联混沌系统和异化图像库的图像加密

提出一种基于轮盘跳跃选择混沌系统和异化图像库变换的图像加密算法。该算法从普通图像中获得每个系统的适应度。运行轮盘赌算法根据其适应度选择不同的混沌系统，轮盘赌算法也用于参数控制，从而有效降低混沌系统的动态退化。本文首先提出异化图像库变换，对约定图像库中的普通图像和多幅图像进行操作，从而大大提高加密的安全性。在加扰扩散中，使用同步加扰扩散。伪随机序列按行和列索引排序，图像由一对行列映射阵列同步加扰和扩散。通过实验结果和安全性分析，该算法具有很好的安全性，能够抵抗各种攻击。
