                   Tunnel EAP Method (TEAP) Version 1
                draft-ietf-emu-eap-tunnel-method-10.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) protocol 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.
