I-D ACTION:draft-ietf-mobileip-aaa-key-12.txt



A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP Routing for Wireless/Mobile Hosts Working Group of the IETF.

	Title		: AAA Registration Keys for Mobile IP
	Author(s)	: C. Perkins, P. Calhoun
	Filename	: draft-ietf-mobileip-aaa-key-12.txt
	Pages		: 26
	Date		: 2003-5-21
	
AAA servers, such as RADIUS and DIAMETER, are in use within the
Internet today to provide authentication and authorization services
for dial-up computers.  Mobile IP requires strong authentication
between the mobile node and its home agent.  When the mobile node
shares a AAA security association with its home AAA server, however,
it is possible to use that security association to create derived
mobility security associations between the mobile node and its home
agent, and again between the mobile node and the foreign agent
currently offering connectivity to the mobile node.  This document
specifies extensions to Mobile IP registration messages that can be
used to create mobility security associations between the mobile node
and its home agent, and/or between the mobile node and a foreign
agent.

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.
