EAP Re-authentication Protocol Extensions for Authenticated Anticipatory
                            Keying (ERP/AAK)
                      draft-ietf-hokey-erp-aak-10

Abstract

   The Extensible Authentication Protocol (EAP) is a generic framework
   supporting multiple types of authentication methods.

   The EAP Re-authentication Protocol (ERP) specifies extensions to EAP
   and the EAP keying hierarchy to support an EAP method-independent
   protocol for efficient re-authentication between the peer and an EAP
   re-authentication server through any authenticator.

   Authenticated Anticipatory Keying (AAK) is a method by which
   cryptographic keying material may be established upon one or more
   candidate attachment points (CAPs) prior to handover.  AAK uses the
   AAA infrastructure for key transport.

   This document specifies the extensions necessary to enable AAK
   support in ERP.
