                   Tunnel EAP Method (TEAP) Version 1
                draft-ietf-emu-eap-tunnel-method-04.txt

Abstract

   This document defines the Tunnel Extensible Authentication Protocol
   (TEAP) version 1.  TEAP is a tunnel based EAP method that enables
   secure communication between a peer and a server by using the
   Transport Layer Security (TLS) to establish a mutually authenticated
   tunnel.  Within the tunnel, Type-Length-Value (TLV) objects are used
   to convey authentication related data between the EAP peer and the
   EAP server.
