Analysis of Channel Error upon Selectively Encrypted H.264 Video

by Mamoona Naveed Asghar, Mohammed Ghanbari, Martin Fleury, Martin J. Reed
"... Abstract—For real-time video streaming applications it is important to preserve both privacy and delay sensitivity. To achieve, this selective encryption exploits the entropy coding stage of hybrid codecs. As streaming applications move towards mobile networks, they become vulnerable to bit errors i ..."

in the wireless channel. This paper is a pioneering analysis of the relative impact of bit errors on the two H.264 codec entropy coders, CAVLC and CABAC. The joint impact of compression and encryption on objective video quality is determined in experiments, when it is found that CAVLC is much more vulnerable

The video encryption scheme based on perceptual encryption algorithm in H.264 standards

by Xueyan Zhang, Huchao Deng, Liangwei Chen - In Proceedings of the 2nd International Conference On Systems Engineering and Modeling , 2013
"... Abstract. To meet the requirement of multimedia video transmission's safety and real-time, this paper provides a conclusion based on video encryption schemes of the encryption algorithm. The solution sorts video data into VLC(variable length code) and FLC(fix-length code),only choose to reconst ..."

1 Confidentiality of a Selectively Encrypted H.264 Coded Video Bit-stream

by Mamoona N. Asghar, Mohammed Ghanbari, Martin Fleury, Martin J. Reed
"... It is an assumption that selective encryption does not strongly protect confidentiality owing to the partial visibility of some video data. This is because, though encryption keys may be difficult to derive, an enhanced version of selectively encrypted video sequence might be found from knowledge of ..."

of the unencrypted parts of the sequence. An efficient selective encryption method for syntax elements of H.264 encoded video was recently proposed at the entropy coding stage of an H.264 encoder. Using this recent scheme as an example, the purpose of this paper is a comprehensive cryptanalysis of selectively
