A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP Security Protocol Working Group of the IETF.

	Title		: Intra-Domain Group Key Management Protocol
	Author(s)	: T. Hardjono, B. Cain, I. Monga,
	Filename	: draft-ietf-ipsec-intragkm-02.txt
	Pages		: 31

This document describes a protocol for intra-domain group key 
management for IP multicast security, based on the framework of 
[HCD99]. In order to support multicast groups, the domain is divided 
into a number of administratively-scoped 'areas'.  A host-member of 
a multicast group is defined to reside within one (and only one) of 
these areas.  The purpose of placing host-members in areas is to 
achieve flexible and efficient key management, particularly in the 
face of the problem of changes (joining, leaving, ejections) in the 
membership of a multicast group. A separate administratively-scoped 
area control-group is defined for each (data) multicast group, for 
the express purpose of key management and other control-message 
delivery.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
