Abstract

   This document defines two EAP extended key usage values and a public
   key certificate extension to carry Wireless LAN (WLAN) System Service
   identifiers (SSIDs).

1.  Introduction

   Several Extensible Authentication Protocol (EAP) [EAP] authentication
   methods employ X.509 public key certificates.  For example, EAP-TLS
   [EAP-TLS] can be used with PPP [PPP] as well as IEEE 802.1X [802.1X].
   PPP is used for dial-up and VPN environments.  IEEE 802.1X defines
   port-based, network access control, and it is used to provide
   authenticated network access for Ethernet, Token Ring, and Wireless
   LANs (WLANs) [802.11].

   Automated selection of certificates for PPP and IEEE 802.1X clients
   is highly desirable.  By using certificate extensions to identify the
   intended environment for a particular certificate, the need for user
   input is minimized.  Further, the certificate extensions facilitate
   the separation of administrative functions associated with
   certificates used for different environments.
