Multicast is an efficient method to deliver multimedia content from a sender to a group of receivers and is gaining popular applications such as real time stock quotes, interactive games, video conference, and live video broadcast or video on demand. Authentication is one of the critical topics in securing multicast in an environment attractive to malicious attacks. MABS includes two schemes MABS-B & MABS-E. The basic scheme MABS-B eliminates the correlation among packets and thus provides the perfect resilience to packet loss, and it is also efficient in terms of latency, computation, and communication overhead due to an efficient cryptographic primitive called batch signature, which supports the authentication of any number of packets simultaneously.
