A New H.264 Video Encryption Scheme Based on Chaotic Cipher
Data encryption is one of the important information security technologies used for safeguarding multimedia content. As chaos has intrinsic properties such as sensitivity to initial conditions, deterministic oscillations and noise-like behavior, it has acquired much attention for video content protection. In this paper, a novel joint compression and encryption scheme based on the context-based adaptive binary arithmetic coding (CABAC) module of H.264 video codec using a chaotic stream cipher is presented. The experimental results show that the H.264 encryption scheme based on a discrete piecewise linear chaotic map is low in complexity, fast in speed and has data compatibility to original data. The proposed scheme provides an efficient way to scramble the video streams and the good performances have the feasibility for H.264 video content protection.
