This paper presents a novel scheme to efficiently secure variable length coded (VLC) multimedia bit streams, such as H.264. The proposed scheme employs code word diffusion and content based shuffling techniques to achieve security. Specifically, it is a combination of a highly secure random number generator based on chaotic maps and a low computation complexity block shuffling procedures. The scheme is ubiquitous to the end users and can be deployed at any node in the network, without requiring any decoding. Its power efficiency and scalability is demonstrated on mobile as well as fixed platforms.
