A New Video Encryption Algorithm for H.264

H.264 is the new Video Encoding World Standard, how to guarantee its security is an urgent problem. In this paper a new video encryption algorithm for H.264 is proposed, which utilized scrambling of intra-prediction, inter-prediction mode and encryption of transform result, motion vector. The results show that the proposed method exhibits nice security, has low impact on compression ration and support direct bit-rate control, moreover it can be realized in real time environment
