Group key management for IP multicast: model & architecture
Thomas Hardjono, Mark Baugher, Hugh Harney · 2002
The Internet key exchange protocol as it stands is unsuitable for secure group and IP multicast communications due to the method of negotiating security association (SA) elements. This paper reports developments in the IETF in this area. In particular, it describes the design of the group key management architecture and group security association (GSA) model within the secure multicast group (SMUG) in the IRTF, and which have recently been carried-over into the multicast security (MSEC) Working Group in the IETF.
