摘　　要：混沌序列具有易于生成、对初值敏感和类白噪声的性质,因而适用于密码系统设计。文中利用广义猫映射的混沌特性来对每一帧原始视频图像进行置乱加密,然后对加密后的视频流进行H.264编码,最后对实验结果进行了分析和总结。实验验证证明:该算法简单,且实时性高,信息隐藏效果好。Chaotic sequence is easy to be generate, sensitive on initial condition and noise like, so it is very applicable to encryption. Using cat mappings chaos characteristic, each frame of original video sequence can be encrypted by permutation. The encrypted video sequence is encoded by H264. The algorithm is simple and has good real-time performance. Finally, the paper is analyzed and summarized by the experimental results.
