"IP multicasting is a communication mechanism in which data are communicated from a server to a set of clients who are interested in receiving those data. Any client can dynamically enter or leave the communication. The main problem of this system is that every client that is interested in receiving the multicast data has to be in a multicast enabled network. The Network Working Group at the Internet Engineering Task Force (IETF) has come up with a solution to this problem. They have developed a protocol named Automatic Multicast Tunneling (AMT). This protocol offers a mechanism to enable the unicast-only clients to join and receive multicast data from a multicast enabled region through an AMT tunnel, which is formed between the two intermediate participants named Gateway and Relay. However, AMT does not provide any Participant Access Control (PAC).\r\nMalla has designed an architecture for adding PAC at the receiver’s end in the AMT environment. His work is based on the assumption that the AMT tunnel is secure and the tunnel can recognize and pass the additional message types that his design requires. We have designed the solution to secure the AMT tunnel. We also defined the additional message types. Lastly, we validated our work using the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool to ensure that our design is secure."
