| 摘 要： | 提出了一种双重混沌的图像加密算法。算法采用Logistic混沌映射和Lorenz混沌系统对图像进行加密。算法首先利用Logistic映射对图像的像素进行置乱,达到改变图像像素点的位置,再运用Lorenz混沌系统对Logistic加密后的图像进行二次加密来改变图像的像素值以达到双重加密的效果。仿真实验表明,该算法具有可行性、执行速度快、密钥量大和加密效果好的优点。 |

| Abstract: | An image encryption algorithm based on dual chaotic system is proposed which using logistic mapping and lorenz system.Firstly,the original image pixel are scrambled using logistic mapping to change their location.Then,the lorenz system is used to encrypt the image again after the first encryption by logistic mapping in order to modify the pixel value.At last,the image is encrypted twice.The simulation shows that the algorthim which provides high encryption efficiency is faster in encryption and has larger k... |
