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 for the foreign agent, 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 mobile node.

This document is a product of the IP Routing for Wireless/Mobile
Hosts Working Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
