| 摘 要： | 为解决全球信息栅格的网络数据的安全问题,提出新的基于五维超混沌系统的图像加密算法,给出全球信息栅格通信体系的基于超混沌的图像加密方案。对生成的两个超混沌序列进行预处理,并置乱图像的像素位置。最后,选择一个混沌序列进行预处理后对图像像素值加密,以改变灰度值。仿真分析结果表明,该加密算法密钥空间大,密钥选择敏感,具有很高的安全性和很好的加密效果。

| Abstract: | A new image encryption algorithm based on five-dimension hyperchaotic system was presented to solve the issues of network data security for global information grid.The image encryption scheme based on hyperchaotic system for the communication system of global information grid was given.Two chaotic sequences were preprocessed to shuffle the positions of image pixel,and a chaotic sequence was selected and preprocessed for pixel value encryption of image to change the gray values.Simulation results and analysis show that the proposed encryption algorithm has the advantages of large key space,key selection sensitivity,high security and good encryption effect. |
