| 摘 要： | 利用混沌序列的特性,提出了一种基于混沌的视频加密算法.首先由Logistic混沌映射生成混沌序列,利用像素值替代方法对视频中每帧图像进行加密,然后利用＂一次传输一个密钥＂的密钥同步方案,设计并实现了一套基于混沌的视频保密通信系统,最后系统测试结果表明该算法具有一定的有效性和保密性能.

| Abstract: | A chaotic video encryption algorithm is presented according to the properties of chaotic sequences. At first, the chaotic sequences are generated by means of Logistic chaotic mapping, and each frame of video is encrypted using the method of pixel value substituting. Then a key synchronization scheme of ＂one transmission with one key＂ is used to design and implement the chaotic video secure communication system. Test results show that the algorithm is valid and has good security. |
