Group security association (GSA) management in IP multicast

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 case. This serves as a basis for a requirements for Group SA for multicast. Finally, the definition and construction of a GSA is described. © 2002 Kluwer Academic / Plenum Publishers, New York.
