MLS improves upon existing protocols such as Signal in group messaging applications. We co-authored the protocol specification and will briefly talk about what motivated the creation of MLS, how it relates to other existing messaging protocols as well as its design process in general.
As a group messaging protocol, the security guarantees provided by MLS go beyond authentication and confidentiality. We will go into detail on what security properties users can expect and take a look under the hood on how MLS works.
While the MLS specification has only been published recently, more work is underway and an ecosystem is already forming around the standard. We’ll touch on topics like MLS implementations, metadata hiding, federation, and interoperability between messengers (also in the context of the new IETF MIMI working group ). And of course we’ll share insights into the future of Messaging Layer Security!
