摘要
为解决视频信息的安全问题,研究了一个基于Lorenz混沌系统的视频加密方案。该方案首先将三维Lorenz混沌系统进行离散化处理,然后运用驱动式响应同步的方式进行同步处理,对随机采集到的AVI视频文件进行混沌加密。通过采用Matlab仿真软件,编写相应的加解密程序进行仿真,最后,对仿真实验结果进行分析,结果表明该方案具有安全性高、灵活性好的特点。
To address the safety of video information, a digital video encryption based on Lorenz chaotic system is studied. Firstly, three-dimensional Lorenz chaotic system is discreted. Then use the corresponding synchronous manner to drive synchroniza- tion. Use random collection of AVI video files to the chaotic encryption. By using Maflab simulation software, preparation of the corresponding encryption and decryption process simulation. Finally, analysis of simulation results shows that the scheme has high security, flexibility.
