The IESG has approved the following document: - 'The Messaging Layer Security (MLS) Protocol' (draft-ietf-mls-protocol-20.txt) as Proposed Standard This document is the product of the Messaging Layer Security Working Group. The IESG contact persons are Paul Wouters and Roman Danyliw. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-mls-protocol/ Technical Summary In this document, we specify a key establishment protocol that provides efficient asynchronous group key establishment with forward secrecy and post compromise security for groups in size ranging from two to thousands. Working Group Summary Smooth sailing in general. Different parties worked well together. Document Quality There are a number of implementations available already. A number of vendors have authors on the document. - MLSpp = open source, deployed in production - OpenMLS = open source - Wickr's implementation = closed source - RingCentral's implementation = closed source, deployed in production - Element's Typescript implementation = open source, only prototype-grade There is strong confidence this protocol will be widely implemented and used. Early reviews brought up issues that were resolved along with the AD Review issues in the latest -17 version. There is a Media Type defined. IANA performed an early review and noted that a few that were addressed. The revised registration was shared with the media-types@ietf.org mailing list, see https://mailarchive.ietf.org/arch/msg/media-types/8HbUs8imKgpwT3cGXKIX-ELN8dQ/ Some discussion happened on whether "message/mls" was the right choice due to some special old/lost meaning of "message", but in the end it stuck with "message/mls". No MIB or Yang items in the document. Personnel Sean Turner is the Document Shepherd. Paul Wouters is the responsible AD.
