RLH: Receiver driven layered hash chaining for multicast data origin authentification

Résumé

Many group-oriented applications, such as broadcasting stock quotes and video-conferencing require data origin authentication of the received traffic. Multicast data origin authentication must take into consideration the scalability and the efficiency of the underlying cryptographic schemes and mechanisms, because multicast groups can be very large and the exchanged data is likely to be heavy in volume (streaming). Besides, multicast data origin authentication must be robust enough against packet loss because most of multicast multimedia applications do not use reliable packet delivery. Therefore, multicast data origin authentication is subject to many concurrent and competitive challenges, when considering these miscellaneous application level requirements and features. In this paper, we propose an efficient multicast data origin authentication protocol based on a novel layered hash-chaining scheme. Our protocol tolerates packet loss and guarantees non-repudiation of media-streaming origin. Furthermore, our protocol allows receivers to make the decision regarding the authentication information redundancy degree depending on the quality of reception in term of packet loss ratio. This novel technique allows to save bandwidth since the packet loss distribution over a large scale network is likely to be not uniform. We have simulated our protocol using NS-2, and the simulation results show that the protocol has remarkable features and efficiency compared to other recent data origin authentication protocols.
