摘　　要：在分析混沌特性的基础上,设计一种基于Logistic混沌序列的图像像素点随机置乱加密算法,将混沌映射后的图像序列,再通过一组随机排序的序列进行置乱处理,最终得到加密图像。仿真实验结果表明,该算法效率高、安全性好,并具有一定抗攻击能力。In the analysis of chaotic behavior, based on the design based on Logistic chaotic sequence of random pixels in an image scrambling encryption algorithm, the chaotic maps the image sequence, and then through a set of randomly ordered sequence scrambling process, and ultimately get encrypted image. Simulation results show that the algorithm efficiency, safety, and has a certain anti-attack capability.
