Request for Comments: RFC 7562 on Transport Layer Security (TLS) Authorization Using Digital Transmission Content Protection (DTCP) Certificates
Question asked by Bruce Barnes - July 9, 2015 at 6:42 PM
Unanswered

Significant controversy, along with some healthy disagreement, on how TLS should work with MX servers, and SmarterMail in particular, was presented by several members of these forums in the article located at:

http://portal.smartertools.com/community/a617/provide-a-choice-of-tls-1_0-or-tls-1_2-in-sm.aspx

The IETF (International Engineering Task Force - keeper of all things standards for Internet Protocols), is about to begin the process of finalizing the standard for TLS 1.3.

Anyone with such a desire can both become a member of, and participate in, the IETF.  The IETF makes the process of finalizing and commenting on protocols one of the most democratic processes anyone will ever participate in and, even if you don't completely understand the dialogue and exchanges, it is a fascinating process to watch.

A good place for newcomers to learn about the IETF is: http://ietf.org/newcomers.html

Part of the process of finalizing the introduction of, or modification of, any protocol, is to create a new "REQUEST FOR COMMENTS" regarding the TRANSPORT LAYER SECURITY (TLS) protocol.  This new protocol is listed under RFC 7562

Here is the formal announcement from the IETF, inviting comments on RFC 7562

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).
