| 摘 要： | 在充分考虑映射的混沌特性以及图像相邻像素间强相关性的基础上,提出基于Arnold变换和混沌理论的图像加密算法.具体的操作过程中,首先利用Arnold变换对图像进行全局置乱处理,然后利用Tent映射对置换后的图像进行混沌加密.实验结果表明:所提出的图像加密算法简便易行,鲁棒性好,安全性高.

| Abstract: | Considering strong correlation between the chaotic characteristics of mapping and adjacent pixels of the image,the image encryption algorithm is introduced based on Arnold transformation and chaos theory.The detailed procedure is as follows:firstly,the image is scrambled by using Arnold transformation.Secondly,the pixels of image are encrypted scramble by using Tent mapping.The experimental results show that the algorithm is simple,convenient,robust and secure. |
