摘要

提出了一种新的位级图像混沌加密算法。首先将平文图像划分为8幅位级图像并将其作为一个整体，利用Chens混沌系统生成混沌序列，进行位级图像置乱，然后利用Logistic混沌序列进行图像像素扩散，最后进行测试仿真和性能分析，并与其他图像加密算法进行比较，测试结果表明所提算法具有较强的安全性和有效性。

Abstract

A new bit-level image encryption algorithm based on chaos is presented with the properties of chaotic sequences and inherent characters of bit-level images.At first

the plain image is divided into 8 bit-level images which are treated as a group.And the bit-level imagesgroup is permutated using chaotic sequences generated by Chens chaotic map.Then the image pixel-level diffusion is carried on using Logistic chaotic sequences.Finally

experiments have been carried out to compare its performance with that of other schemes

and the results justify the superior security of our proposed algorithm.
