摘要
本文设计了一种结合Cat和Logistic映射的混合型混沌加密算法。首先文章给出了该图像加解密的算法流程,在置乱变换和扩散变换主要算法程序的基础上,对实验结果从密钥空间、图像的直方图、图像的相关性、图像的信息熵等方面进行了分析,证明该算法对图像信息加解密具有良好的效果。
This paper introduces a design combined with Cat and Logistic mapping of mixed chaotic encryption algorithm.First,the paper gives the image encryption algorithm,scrambling transformation and diffusion in major transformation algorithm procedures,on the basis of experimental results from the key space and the image histogram,image correlation,the information entropy image are analyzed,the algorithm of image information encryption has good effect.
