(U)SIM based PCP Authentication
draft-chen-pcp-authentication-sim-00
Abstract
With (U)SIM support, PCP authentication could leverage the
credentials stored in (U)SIM. The document details PCP
authentication considerations based on (U)SIM support. The
authentication procedures in EAP and GBA framework have been
specifically elaborated. In order to complete the process, new code
and option are also proposed.

1. Introduction
Mobile network is experiencing the significant traffic changes over
the past few years. With Long Term Evolution (LTE) advance, plenty
of data services have been appreared to be major traffic on the
network. The Port Control Protocol[RFC6887] could facilitate data
paths through NAT/Firewell and optimize data traffic behavior. It's
obvious a 3rd Generation Partnership Project (3GPP) network can
benefit from the use of the PCP service.
[I-D.chen-pcp-mobile-deployment]has enumurated several considerations
in a mobile environment. Subsribers take advantage of (U)SIM to
provide the security guarantee. Hence, PCP clients could also
leverage the credential to perform authentication.
This document describes the uses of (U)SIM specific authentication
which is compatible with [I-D.ietf-pcp-authentication]. A new option
is proposed to assist the completion of process.
2. PCP Authentication with (U)SIM
A permanent key is stored on the (U)SIM card and in AAA nodes (e.g.
HLR/HSS) in the mobile network. The key has been to pass through the
authentication. Afterwards, derived keys are generated for chipering
and integrity protection of user-plan and control plane traffic. The
use of (U)SIM to PCP authentication is applicable to WLAN access and
3GPP access cases. The following demonstrates the scenarios with
different frameworks.

2.1. EAP Framework
With the support of (U)SIM cards, UEs could take the credentials from
(U)SIM cards and perform EAP-SIM[RFC4186]/EAP-AKA[RFC4187]/EAP-
AKA'[RFC5448] get through the authentication. The network has been
shown as the below.
