GSMA Finally Brings E2EE to RCS: Android and iOS Users Can Now Exchange Secrets (and Memes) Securely!

The GSMA has announced end-to-end encryption for Rich Communications Services, enhancing security for messages between Android and iOS. This marks RCS as the first large-scale service to support interoperable E2EE across different platforms, ensuring confidential communication as messages traverse the digital airwaves, now protected like a paranoid squirrel hoarding its nuts.

Hot Take:

Looks like RCS just got a whole lot more secure! Time for Android and iOS to stop their “who’s more secure” squabble and start playing nice in the encrypted sandbox. Who knew the peace treaty would come wrapped in a security protocol?

Key Points:

  • GSMA has announced end-to-end encryption (E2EE) support for RCS, enhancing message security across platforms.
  • The new RCS specifications incorporate the Messaging Layer Security (MLS) protocol.
  • RCS becomes the first large-scale messaging service to offer interoperable E2EE among different client implementations.
  • Google’s RCS implementation in the Messages app currently uses the Signal protocol for encryption but is limited to Android-to-Android communication.
  • Google and Apple are both moving towards MLS implementation for cross-platform secure messaging.
