Abstract:

   The Messaging Layer Security (MLS) protocol (I-D.ietf-mls-protocol)
   provides a Group Key Agreement protocol for messaging applications.
   MLS is meant to protect against eavesdropping, tampering, message
   forgery, and provide Forward Secrecy (FS) and Post-Compromise
   Security (PCS).

   This document describes the architecture for using MLS in a general
   secure group messaging infrastructure and defines the security goals
   for MLS.  It provides guidance on building a group messaging system
   and discusses security and privacy tradeoffs offered by multiple
   security mechanisms that are part of the MLS protocol (e.g.,
   frequency of public encryption key rotation).  The document also
   provides guidance for parts of the infrastructure that are not
   standardized by MLS and are instead left to the application.

   While the recommendations of this document are not mandatory to
   follow in order to interoperate at the protocol level, they affect
   the overall security guarantees that are achieved by a messaging
   application.  This is especially true in the case of active
   adversaries that are able to compromise clients, the delivery
   service, or the authentication service.
