Abstract

To enable widespread commercial stream services, authentication is an important and challenging problem. As for multicast authentication, recently proposed schemes well-operate in adversarial network environment where an enemy can inject a large amount of invalid packets to choke the decoding process in the receivers, at the expense of a large communication overhead. In this paper, we present two efficient DoS resistant multicast authentication algorithms. To detect DoS attack, they require loose time-syncronization or delay of sending the packets, respectively. Compared with the previous schemes, they have much lower communication overhead and smaller computation cost on the receivers.
