Abstract

This work describes the Group Security Association (GSA) Management model and protocol as developed in the Secure Multicast Group (SMUG) in the IETF. The background reasoning from the Internet Key Exchange (IKE) protocol perspective is explained, together with the notion of Security Associations (SA) in the unicast cast. This serves as a basis for requirements for Group SA for multicast. Finally, the definition and construction of a GSA is described.
