摘要
论述了一种基于混沌映射的图像保密通信系统。加解密算法应用了4个一维混沌映射,采用了图像置乱和混沌掩盖同时进行的方法,并使用了扩散机制。该算法具有加解密效果良好、适应性强、鲁棒性强、加解密速度快等特点。该软件系统可以处理多种格式和类型的图像,并实现了将其在因特网上以点对点方式进行传输。
A system for image secure communication based on chaotic maps is presented.To encrypt and decrypt image,the algorithm employs four 1D chaotic maps and diffusion mechanism and combines image permutation and chaos mask.The algorithm has characteristics of fine effect,strong adaptability,good robustness and higher encryption speed.This software can process many formats and types of images and transmit them by peer-to-peer communication at Internet.
