Fast protection of H.264/AVC by selective encryption of CABAC for I & P frames
This paper presents a novel method for the protection of copyrighted multimedia content. The problem of selective encryption (SE) is being addressed along with the compression for the state of the art video codec H.264/AVC. SE is performed in the context-based adaptive binary arithmetic coding (CABAC) module of video codec. For this purpose, CABAC is converted to an encryption cipher. It has be...

متن کاملAn Effective Selective Encryption Scheme for H.264 Video based on Chaotic Qi System
With the wide use of H.264 in Internet and wireless network, many concerns have been made to the security of it. Aiming at providing an effective content protection method for H.264 video, a novel selective encryption scheme based on chaotic Qi system is proposed in this paper. The unpredictability of chaotic system is implemented to construct a pseudo-random number generator based on the 3-dim...
