Connection-Oriented Media Transport over the Transport Layer Security Protocol in the Session Description Protocol
RFC 4572, “Connection-Oriented Media Transport over the Transport Layer Security Protocol in the Session Description Protocol”, is a Proposed Standard document published in July 2006 by J. Lennox. It updates RFC 4145. It has been obsoleted by RFC 8122 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document specifies how to establish secure connection-oriented media transport sessions over the Transport Layer Security (TLS) protocol using the Session Description Protocol (SDP). It defines a new SDP protocol identifier, 'TCP/TLS'. It also defines the syntax and semantics for an SDP 'fingerprint' attribute that identifies the certificate that will be presented for the TLS session. This mechanism allows media transport over TLS connections to be established securely, so long as the integrity of session descriptions is assured.
This document extends and updates RFC 4145. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
