| 摘 要： | 文章提出了一种新的基于混沌映射的加密算法，将图像的像素值换算为二进制，然后利用混沌序列对其某几位变换来实现加密。该方法不需要对轨道分布的先验知识，不只适用于Logistic混沌系统，而且很好地利用了混沌的特性。实验结果表明，该算法密钥敏感、密钥空间大，可有效保障加密图像的安全。同时研究了加密图像直方图的安全性。

| Abstract: | A digital image encryption algorithm based on Logistic chaotic sequence is presented.The pixels are changed to binary system.The binary sequence is counterchanged by Chaotic Sequence.The proposed algorithm needn't transcendental knowledge of orbit distributing.So that people could choose not only Logistic Chaotic Sequence.Characteristic of Chaotic Sequence is well utilized.The experiment shows that it has the property of key sensitivity,high key space.The safety of histogram of encrypted images is investigated. |
