Most fashionable shopper messaging platforms (together with Google Messages) assist end-to-end encryption, however customers right now are restricted to speaking with contacts who use the identical platform. This is the reason Google is strongly supportive of regulatory efforts that require interoperability for giant end-to-end messaging platforms.

For interoperability to reach apply, nevertheless, laws have to be mixed with open, industry-vetted, requirements, significantly within the space of privateness, safety, and end-to-end encryption. With out sturdy standardization, the outcome can be a spaghetti of advert hoc middleware that would decrease safety requirements to cater for the bottom widespread denominator and lift implementation prices, significantly for smaller suppliers. Lack of standardization would additionally make superior options akin to end-to-end encrypted group messaging not possible in apply – group messages must be encrypted and delivered a number of occasions to cater for each completely different protocol.

With the current publication of the IETF’s Message Layer Safety (MLS) specification RFC 9420, messaging customers can look ahead to this actuality. For the primary time, MLS allows sensible interoperability throughout providers and platforms, scaling to teams of hundreds of multi-device customers. It’s also versatile sufficient to permit suppliers to tackle rising threats to person privateness and safety, akin to quantum computing.

By making certain a uniformly excessive safety and privateness bar that customers can belief, MLS will unleash an enormous subject of latest alternatives for the customers and builders of interoperable messaging providers that undertake it. This is the reason we intend to construct MLS into Google Messages and assist its large deployment throughout the {industry} by open sourcing our implementation within the Android codebase.
