摘要

利用耦合映象格子的时空混沌特性，研究提出了一种混沌图像加密算法.首先由耦合映象格子产生随机数序列，将平文图像划分为8幅位级图像并进行位级图像置乱；然后选择对应的随机数序列组合，采用逐位异或运算进行图像像素扩散；测试结果表明所提算法比其它算法具有更好的加密性能和有效性.

Abstract

A chaotic image encryption algorithm is presented with the spatiotemporal chaotic properties of coupled map lattices.With the random number sequences generated from coupled map lattices

8 bit-level images divided from the plain image are permuted as a group.Then the image pixel-level diffusion is carried on bitwise XOR operation with selecting a corresponding combination of random number sequences.Simulation results show that the performance and security of the proposed algorithm is better than those of other existing algorithms.
