I-D ACTION:draft-ietf-mobileip-rfc3012bis-05.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		: Mobile IPv4 Challenge/Response Extensions (revised)
	Author(s)	: C. Perkins, P. Calhoun, J. Bharatia
	Filename	: draft-ietf-mobileip-rfc3012bis-05.txt
	Pages		: 23
	Date		: 2003-5-27
	
Mobile IP, as originally specified, defines an authentication
extension (the Mobile-Foreign Authentication extension) by
which a mobile node can authenticate itself to a foreign agent.
Unfortunately, that extension does not provide the foreign agent
any direct guarantee that the protocol is protected from replays,
and does not allow for the use of CHAP for authenticating portable
computer devices.  In this specification, we define extensions for
the Mobile IP Agent Advertisements and the Registration Request
that allow a foreign agent to use a challenge/response mechanism to
authenticate the mobile node.  This document obsoletes RFC 3012.

In the body type:

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.
