一种基于Logistic映射的混沌图像加密算法

A Chaotic Image Encryption Algorithm Based on Logistic Map

为了保证数字图像在网络传输中的安全性和可靠性,提出了一种基于Logistic映射的混沌图像加密算法,并对其安全性进行了分析,包括密钥空间分析、敏感性分析和信息熵分析。算法以Matlab 8.0仿真实现,实验结果证明了该加密算法具有较高的安全性。

In order to ensure the security and reliability of digital image when transferred on the network, an image encryption algorithm based onchaotic Logistic map was proposed, and the security of this algorithm, including key space, statistical and difference was analysed. The algorithm was implemented in the Matlab 8 simulation, and the experimental results showed that the security of the encryption algorithm was high.
