The IESG has approved the Internet-Draft 'Mobile IP Challenge/Response Extensions' <draft-ietf-mobileip-challenge-13.txt> as a Proposed Standard. This document is the product of the IP Routing for Wireless/Mobile Hosts Working Group. The IESG contact persons are David Oran and Rob Coltun. Technical Summary 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, this extension does not provide ironclad replay protection, from the point of view of the foreign agent, and does not allow for the use of existing techniques (such as CHAP) for authenticating portable computer devices. This specification, defines extensions for the Mobile IP Agent Advertisements and the Registration Request that allow a foreign agent to a use challenge/response mechanism to authenticate a mobile node that is roaming in it's serving area. Working Group Summary ---------------------- Two WG last calls have been completed on this draft since October '99, the most recent one in Jan 2000. The draft has undergone multiple revisions based on the feedback received by the authors via the discussion list and also at IETF46. WG members have not expressed any dissent about this draft. The TIA 45.6 body has been very supportive of this draft as this spec is a key component of the 3 wireless data architetcure put forth by them. Protocol Quality ---------------- The proposal in this I-D is the addition of three new extensions to Mobile IP. 1. Mobile IP Agent Advertisement Challenge Extension - Part of Agent Advertisement 2. MN-FA Challenge Extension - Registration request from the MN to the FA 3. Generalized Mobile IP Authentication Extension - This spec specifies the MN-AAA Authentication subtype associated with the Generalized Auth extension. This is also included in the Reg request coming from the MN Implementations of this I-D exist. The exact number is not known at this time. Mobile IP implementations at Connectathon 2000 (1st week of March) will be testing this feature. The results will be posted therefater. This specification was reviewed for the IESG by Dave Oran. Note to RFC Editor: 1) In Section 7 (Reserved SPIs for Mobile IP), please replace http://www.isi.edu/in-notes/iana/assignments/mobileip-numbers. with http://www.iana.org/numbers.html 2) In Section 11 (IANA Considerations), please replace must be specified and approved by the Mobile IP working group with must be specified and approved by a designated expert.
