A New Encryption Scheme for H.264 Real-Time Video Transmission

BAO Xian-yu,JIANG Jian-guo,LI Yuan(School of Computer & Information,Hefei University of Technology,Hefei,Anhui 230009,China)  
H.264 is the latest video coding standard developed by ITU-T and ISO/IEC,and its security is becoming a research focus.Several candidate domains are investigated to apply encryption for H.264 and,a new video encryption scheme combining encryption with compression is proposed in this paper.It includes novel simultaneous CAVLC(Context-based Adaptive Variable-Length Coding)and QTC(quantized transform coefficients)encryption and prediction mode,motion vectors scrambling.Theoretical analysis and experimental results show that the scheme is fast,secure,and robust to transmission errors,moreover,it has very limited adverse impact on the compact ratio.
