RFC 8122 Title: Connection-Oriented Media Transport over the Transport Layer Security (TLS) Protocol in the Session Description Protocol (SDP) Author: J. Lennox, C. Holmberg Status: Standards Track Stream: IETF Date: March 2017 Mailbox: jonathan@vidyo.com, christer.holmberg@ericsson.com Pages: 18 Characters: 42792 Obsoletes: RFC 4572 I-D Tag: draft-ietf-mmusic-4572-update-13.txt URL: https://www.rfc-editor.org/info/rfc8122 DOI: 10.17487/RFC8122 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. This document is a product of the Multiparty Multimedia Session Control Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
