Abstract: Many distributed applications require a reliable group communication system to provide coordination among the application components. Such group communication is often conducted over a wide-area network like the global Internet. Messages sentover the Internet often traverse several independently controlled networks and are thus susceptible to attacks. Consequently, distributed applications need mechanisms to secure this communication. This paper describes a secure group communication protocol. The secure group layer (SGL) bundles a reliable group communication system, a group authorization and access control mechanism, and a group key agreement protocol to provide a comprehensive and practical secure group communication platform. SGL also encapsulates the standard message security services (i.e, confidentiality, authenticity and integrity). A numberofchallenging issues encountered in the design of SGL are brought to light and experimental results obtained with a prototype im...
