Definition of Master Key between PANA Client and Enforcement Point
Abstract
This document defines a master key used between a client of the
Protocol for carrying Authentication for Network Access (PANA) and an
enforcement point, for bootstrapping lower-layer ciphering. The
master key is derived from the Master Session Key of the Extensible
Authentication Protocol as a result of successful PANA
authentication. The master key guarantees cryptographic independence
among enforcement points bootstrapped from PANA authentication across
different address families.

RFC 5807 PaC-EP Master Key March 2010
1. Introduction
The Protocol for carrying Authentication for Network Access (PANA)
[RFC5191] is designed to facilitate network access authentication and
authorization of clients in access networks. It carries Extensible
Authentication Protocol (EAP) [RFC3748] between a PANA Client (PaC)
and a PANA Authentication Agent (PAA) where the PAA functions as an
authentication gateway to the Authentication Server (AS). The PANA
framework [RFC5193] defines an another entity referred to as an
Enforcement Point (EP), which resides in the access network and
allows access (data traffic) of authorized PaCs while preventing
access of others depending on the PANA authentication and
authorization result (Figure 1). The EP and PAA may be implemented
on the same device or separate devices.
