A new Request for Comments is now available in online RFC libraries. RFC 9335 Title: Completely Encrypting RTP Header Extensions and Contributing Sources Author: J. Uberti, C. Jennings, S. Murillo Status: Standards Track Stream: IETF Date: January 2023 Mailbox: justin@uberti.name, fluffy@iii.ca, sergio.garcia.murillo@cosmosoftware.io Pages: 21 Updates: RFC 3711 I-D Tag: draft-ietf-avtcore-cryptex-08.txt URL: https://www.rfc-editor.org/info/rfc9335 DOI: 10.17487/RFC9335 While the Secure Real-time Transport Protocol (SRTP) provides confidentiality for the contents of a media packet, a significant amount of metadata is left unprotected, including RTP header extensions and contributing sources (CSRCs). However, this data can be moderately sensitive in many applications. While there have been previous attempts to protect this data, they have had limited deployment, due to complexity as well as technical limitations. This document updates RFC 3711, the SRTP specification, and defines Cryptex as a new mechanism that completely encrypts header extensions and CSRCs and uses simpler Session Description Protocol (SDP) signaling with the goal of facilitating deployment. This document is a product of the Audio/Video Transport Core Maintenance 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. Distribution of this memo is unlimited. This announcement is sent to the IETF-Announce and rfc-dist lists.
