  Transport Layer Security (TLS) Authorization Using DTCP Certificate
                      draft-dthakore-tls-authz-06

Abstract

   This document specifies the use of Digital Transmission Content
   Protection (DTCP) certificates as an authorization data type in the
   authorization extension for the Transport Layer Security (TLS)
   Protocol.  This is in accordance with the guidelines for
   authorization extensions as specified in [RFC5878].  As with other
   TLS extensions, this authorization data can be included in the client
   and server Hello messages to confirm that both parties support the
   desired authorization data types.  If supported by both the client
   and the server, DTCP certificates are exchanged in the supplemental
   data TLS handshake message as specified in RFC4680.  This
   authorization data type extension is in support of devices containing
   DTCP certificates, issued by the Digital Transmission Licensing
   Administrator [DTLA].

1.  Introduction

   The Transport Layer Security (TLS) protocol (TLS1.0 [RFC2246], TLS1.1
   [RFC4346], TLS1.2 [RFC5246]) is being used in an ever increasing
   variety of operational environments, the most common among which is
   its use in securing HTTP traffic ([RFC2818]).  [RFC5878] introduces
   extensions that enable TLS to operate in environments where
   authorization information needs to be exchanged between the client
