Title : Keying and signaling for wireless access and handover using EAP (EAP-HR)
Author(s) : M. Nakhjiri
Filename : draft-nakhjiri-hokey-hierarchy-04.txt
Pages : 23
Date : 2007-4-6
Problems related to AAA-based key management for facilitating
optimized secure handovers and re-authentications have been described
in several problem statements ([I-D.nakhjiri-aaa-hokey-ps],
[I-D.ohba-hokey-3party-keydist-ps] and [I-D.ietf-hokey-reauth-ps]).
This document provides description of an EAP initiated key hierarchy
as part of the solution for those problems. Additionally a modified
version of the 3-party key distribution orocess
([I-D.ohba-hokey-3party-keydist-ps]) is proposed to provide a binding
between the generated/distributed keys and the parties using the
keys. A new EAP method called EAP handover and re-authentication
(EAP_HR) is also described to significantly reduce handover keying
and re-authentication latency. AAA attributes and EAP type data
extensions are also covered.

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
Internet-Draft.
