H2A: Hybrid Hash-chaining scheme for Adaptive multicast source authentication of media-streaming

In this paper, we propose a hybrid hash-chaining scheme in conjunction with an adaptive and efficient data source authentication protocol which tolerates packet loss and guarantees non-repudiation of media-streaming origin. 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 source authentication protocols.
