Transport Layer Security (TLS) Authorization Using
Digital Transmission Content Protection (DTCP) Certificates
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 RFC 5878. 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 RFC 4680. This
authorization data type extension is in support of devices containing
DTCP certificates issued by the Digital Transmission Licensing
Administrator (DTLA).

RFC 7562 TLS Auth Using DTCP July 2015
1. Introduction
The Transport Layer Security (TLS) protocol (see TLS 1.0 [RFC2246],
TLS 1.1 [RFC4346], and 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]
