A Novel Message Source Authentication Protocol for Multicast Group
Changsheng Wan, Aiqun Hu, Juan Zhang · 2008
This paper proposes an elliptic curve based message source authentication mechanism for multicast. When a new sender signs a message and multicasts it to the receivers, the receivers need not consult the group manager for getting the public key of the sender. Hence the denial-of-service attack is avoided. Therefore, our scheme enjoys both efficiency and security compared to current schemes.
