For secure stream media applications, block spatial scrambling can be used as a practice video encryption approach. The scrambling approaches commonly used for encryption of H.263/MPEG-4 stream can not be used for H.264/AVC's directly because the neighboring MacroBlocks, residual blocks and codewords of H.264/AVC stream data are context-sensitive. A novel format-compliant residual block spatial scrambling algorithm for H.264/AVC stream encryption is proposed in this article. In the algorithm, the residual blocks are categorized into different groups and each residual block group uses different random shuffling table, which is generated by the chaotic cryptosystem respectively. The experimental results show that H.264/AVC video stream could be encrypted in real-time while the format is kept compliant.
