Video Encryption Based on Generalized Cat Mapping and H.264
Dan He · The Internet of Things · 2012
Chaotic sequence is easy to be generate, sensitive on initial condition and noise like, so it is very applicable to encryption. Using cat mapping's 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.
