                    (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.
