Connection-Oriented Media Transport over the Transport Layer Security Protocol in the Session Description Protocol
RFC 8122, “Connection-Oriented Media Transport over the Transport Layer Security Protocol in the Session Description Protocol”, is a Proposed Standard document published in March 2017 by J. Lennox, C. Holmberg. It obsoletes RFC 4572. It has since been updated by RFC 8844. 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 the 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 obsoletes RFC 4572 by clarifying the usage of multiple fingerprints.
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.
