Independent Submission D. Thakore Request for Comments: 7562 CableLabs Category: Informational July 2015 ISSN: 2070-1721 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).

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] introduces extensions that enable TLS to operate in environments where authorization information needs to be exchanged between the client and the server before any protected data is exchanged.
