| 摘 要： | 提出了1种基于Amold变换和Logistic映射的混沌加密算法，首先将彩色图片3个RGB颜色通道进行分离，再把它们转换成灰度图，然后分别通过不同的方法分别将这3个通道的灰度图像进行置乱或改变灰度值，最后把3个密文组合成RGB模式的密文．对算法进行了密钥空间分析等测试，仿真实验表明：本算法有很好的加密效果和安全性．

| Abstract: | This paper presents a novel image encryption scheme based on the Arnold mapping and the Logistic mapping. First separated the three channels of a RGB mode image, then transformed them into 3 two dimensional grey images. We respectively scramblinged these gray images of the three colour channels or changed their gray value by different methods, we finally combined the three ciphertext into a RGB mode image.The results of experiment simulation show that the algorithm is valid and has good performance. |
