摘要

利用混沌序列的特性

提出了一种新的混沌图像加密算法

并进行改进.首先由复合混沌映射生成混沌序列

再结合灰度值替代和图像位置置乱方法对图像进行加密

然后进行实验仿真和性能分析

结果表明该算法具有一定的有效性和良好的加密性能.

Abstract

A new image encryption algorithm is presented and improved based on chaotic sequence.At first

the chaotic sequences are generated by Logistic chaotic map.Then the image is encrypted combining the method of grey value substituting and position shuffling.The results of experiment simulation and performance analysis show that the algorithm is valid and has good performance.
