说明:  :提出了一种新的基于混沌映射与排序变换的图像加密算法。混沌序列具有容易生成、对初始条件敏感以及具备白噪声的统计特性等优点。该算法利用混沌映射对初值的敏感性和伪随机性,通过对生成的混沌序列排序来得到图像置乱的地址变换码,由于排序的不规则性,因此新的混沌图像置乱算法具有较强的保密性能。通过对该算法的置乱性能分 析并进行仿真实验,结果表明,新算法具有良好的图像加密性能。
(his paper presents a new encryption algorithm based on chaotic map image transformation and sorting. Chaotic sequence is easy to generate, sensitive to initial conditions, and with white noise statistical properties. The algorithm uses chaotic maps of sensitivity to initial values ​ ​ and pseudo-randomness, get the address of image scrambling transformation code generated chaotic sequence sorting, sort of irregular, so the new chaotic image scrambling algorithm has more strong performance of confidentiality. Scrambling performance points by the algorithm Analysis and simulation results show that the new algorithm has a good image encryption performanc)
