Secure and Efficient Source Authentication for Multicast Based on Message Authentication Codes

Multicast communication is becoming the basis for a growing number of applications. It is therefor critical to provide sound security mechanisms for multicast communication. Yet,existing security protocols for multicast offer only partial solutions. Owing to the source authentication of multicast that is one of major security concerns of multicast communication,a secure and efficient source authentication scheme for multicast is present by means of Message Authentication Codes.
