The GSMA association has unveiled the new version of the RCS messaging protocol that supports end-to-end encryption (E2EE) for data privacy, as previously announced. The RCS E2EE specification is built on the Messaging Layer Security (MLS) protocol, an IETF standard that Google has declared support for since 2023. This implies that on the Android platform, there should be no issues regarding this development.
An Apple spokesperson confirmed to The Verge that they will also support RCS E2EE on their operating systems – iOS, iPadOS, macOS, and WatchOS in the future (no specific timeline provided). Currently, Apple supports encrypted iMessages and unencrypted RCS messages.
TLDR: GSMA introduces new RCS version with end-to-end encryption; Google supports it on Android while Apple plans to support it on their devices in the future.
