| 摘 要： | 研究了一种基于三维Baker映射与复合混沌序列的图像加密新算法,该算法选用三种混沌序列,即一维无限折叠映射、二维Henon映射和一维Logistic映射对原图像进行位置置乱与像素值扩散处理.在置乱过程中运用一个判决条件来决定两种置乱方法的使用顺序,比使用同一个混沌系统多次置乱更加理想.仿真实验表明,算法具有较强的加密效果和安全性.

| Abstract: | An image-encrypted algorithm based on 3D Baker mapping and complicated chaotic sequence is proposed.The encrypted algorithm processes the color values of each image point and the array of original image based on three kinds of chaotic sequences,i.e.the 1D infinite collapse mapping and the 2D Henon mapping and the 1D Logistic mapping.The service sequence of the two scrambling algorithm will be decided by a judicative condition,and this method is better than that using the same chaotic system with the chaos m... |
