基于视频压缩标准H.264的视频加密算法

提出一种混沌的视频加密算法, 该算法利用混沌函数产生加密序列, 根据视频压缩标准H.264的原理和特点, 先对离散余弦进行变换, 并将量化后的矩阵块作空间置乱和数值扩散, 再对熵编码后的二进制序列进一步加密处理, 解决了视频信息传输的加密问题. 并在H.264参考软件JM12.4上实现了混沌的视频加密算法.

Video Encryption Algorithm Based on H.264 Standard

A new chaotic video encryption algorithm presented in the paper makes full use of chaotic function to generate encryption series.According to the principle and characteristics of the video compression standard-H.264,first,space replacement and numerical diffusion are conducted to the coefficients of block matrices after discrete cosine transform quantization,and then in order to solve the problem of encryption in video data transmission,the binary sequences after entropy coding are encrypted further.The cha...
