Abstract
The Mobile IP and Authentication, Authorization, Accounting (AAA)
working groups are currently looking at defining the requirements for
Authentication, Authorization, and Accounting. This document
contains the requirements which would have to be supported by a AAA
service to aid in providing Mobile IP services.
1. Introduction
Clients obtain Internet services by negotiating a point of attachment
to a "home domain", generally from an ISP, or other organization from
which service requests are made, and fulfilled. With the increasing
popularity of mobile devices, a need has been generated to allow
users to attach to any domain convenient to their current location.
In this way, a client needs access to resources being provided by an
administrative domain different than their home domain (called a
"foreign domain"). The need for service from a foreign domain
requires, in many models, Authorization, which leads directly to
Authentication, and of course Accounting (whence, "AAA"). There is
some argument which of these leads to, or is derived from the others,
but there is common agreement that the three AAA functions are
closely interdependent.
