Google's new 'end-to-end encrypted' Gmail feature isn't true E2EE as commonly understood, as the keys are managed by the organization deploying it, allowing potential administrative access. It aims to simplify compliance with security regulations by replacing complex systems like S/MIME.
The GSMA has announced that RCS Universal Profile 3.0 will add end-to-end encryption via the Messaging Layer Security (MLS) protocol, with both Google and Apple confirming support. Apple and Google will release updates to their respective platforms to implement this new standard.
