“…In [39] there is an analysis of a system for H.264/AVC I-frame only SE which also brings low computation, low bitrate overhead and decoder format compliance after encryption, though no analysis of the video distortion or image structural distortion arising from partial encryption was made in [39]. As another example employing CABAC-based encryption in [40] only I-and P-frames are selectively encrypted. The underlying motivation behind such schemes is that even if the bitstream is captured by packet 'sniffer' software or stored by some means at the receiver device successful decoding of the P-or B-frame compression data depends on being able to decode the corresponding I-frame within a Group of Pictures (GOP) [41].…”

“…The proposal of [46] also incurs a bit-rate overhead. The computational cost of the schemes described in both [24] and [40] is high because they used AES-based encryption of the selected parameters. Thus, the comparison of Table 10 shows that Scheme 1 is efficient with low computational cost and no bandwidth overhead.…”

“…As shown in " Fig. 1", an encryption algorithm could be placed before, during, or after the compression process [2] [3]. The video encryption algorithms placed before or after compression are called encryption algorithms independent of the compression while those executed during the compression process are called encryption algorithms joint compression.…”

Abstract-H.264 video coding standard is one of the most promising techniques for the future video communications. In fact, it supports a broad range of applications. Accordingly, with the continuous promotion of multimedia services, H.264 has been widely used in real-world applications. A major concern in the design of H.264 encryption algorithms is how to achieve a sufficiently high security level, while maintaining the efficiency of the underlying compression process. In this paper a new selective encryption scheme for the H.264 standard is presented. The aim of this work is to study the security of the H.264 standard in order to propose the appropriate design of a hardware cryptoprocessor based on a stream cipher algorithm. Since the proposed cryptosystem is mainly dedicated to the multimedia applications, it provides multiple security levels in order to satisfy the requirements of various applications for different purposes while ensuring higher coding efficiency. Different performance analyses were made in order to evaluate the new encryption system. The experimental results showed the reliability and the robustness of the proposed technique.

“…That is to say the bitrate overhead increases, while the video quality remains the same. Another promising technique applied in [7] to non-scalable H.264/AVC also uses SE on the codewords/bin-strings of the entropy coder. This has the advantage of preserving the bitrate, being standard compliant and involving negligible overhead.…”

The distribution of copyrighted scalable video content to differing digital devices should be protected during rendering and transmission. The proposed scheme is applied to H.264 Scalable Video Coding (SVC) CABAC bin strings in a compression-friendly and decoder format compliant manner. It achieves this by careful selection of the entropy coder syntax elements for selective encryption (SE) with respect to SVC. Tests show that: decoding delay is small, replacement and key substitution attacks are fruitless; there is no increase in bitrate; and the stream remains format compliant. The proposed SE scheme is extremely suitable for video distribution to users who have subscribed to differing video qualities on medium-to highcomputationally capable digital devices.
