Multicast gives professional large-scale content distribution by providing an efficient transport mechanism for one-to-many and many-to-many communications. There is a number of security issues in multicast communication directly related to the specific nature of multicast. In the authors' paper, they concentrate on the multicast authentication problem. There are four important requirements of multicast communication protocols: to perform authentication in real-time, to resist packet loss and pollution at-tacks, to have low communication and computation over-heads and to have resistance to replay attacks.
