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 existing techniques (such as 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
Furthermore, this document updates RFC 3344  by including new
authentication extension called the Mobile-AAA Authentication
extension. This new extension is provided so that a mobile node
can supply credentials for authorization using commonly available
AAA infrastructure elements. This Authorization-enabling extension
MAY co-exist in the same Registration Request with Authentication
extensions defined for Mobile IP Registration by . This document
obsoletes RFC 3012.

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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
