Abstract:

Effective key management has been a fundamental prelude before encryption of single-layer video streams in the public Internet. In addition to single-layer video, multi-layer video can provide scalable on-demand video streaming, especially within a mobile network. The objective of the proposed mechanism was to reduce the number of keys exchanged for setting up an encrypted scalable video stream. The method proposed had access to the highest enhancement layer to which users were entitled, together with access to all layers below down to the base layer. A low-latency key exchange mechanism i.e. Zimmermann Real-time Transport Protocol (ZRTP) was used for the hierarchical keys? generation of scalable video in conjunction with an in-house form of selective encryption. The results confirmed that the keys? generation time was reduced by 7 µs than the previous techniques. It was also concluded from the results that the selective encryption method was decoder compatible and produced zero bit-rate overhead.
