Apple to support encrypted RCS messaging

Apple to support encrypted RCS messaging is profiled by BTW Media because published evidence links it to internet infrastructure, governance, operational dependencies, or market visibility.

• Apple to introduce end-to-end encryption for RCS messages.
• Android and iPhone users will benefit from enhanced privacy.

What happened: Encrypted messaging for iPhone and Android

Apple is set to support encrypted RCS messaging with Android users, enhancing privacy and security for cross-platform messaging. The GSM Association has updated RCS specs to include end-to-end encryption (E2EE) based on the Messaging Layer Security (MLS) protocol. This update allows interoperable encryption between different platforms for the first time.

iPhone and Android users will now be able to exchange E2EE RCS messages, making it harder for third parties to see text contents. The GSM Association started working on this in September last year, collaborating with mobile operators, device manufacturers, and technology providers, including Apple.

Apple introduced RCS support in iPhones with an iOS 18 update in September. Although iMessage already supported E2EE, it wasn’t available for RCS messaging because the previous RCS standard lacked cross-platform support. Google Messages enabled E2EE for RCS texts by default, but only conversations between Google Messages users were E2EE, not those with iMessage users or other RCS clients on Android.

Why it is important:

The introduction of end-to-end encryption for RCS messages is crucial as it significantly enhances privacy and security for users. This feature prevents unauthorised parties from accessing message content, thus protecting user data and communications. As messaging becomes increasingly vital, ensuring message security is paramount.

This advancement aligns with growing demand for secure communication channels, especially amid rising concerns over data privacy and security. By supporting E2EE RCS messages, Apple and Google are meeting these demands, offering users a more secure messaging experience. This move is expected to foster greater trust in digital messaging platforms and encourage wider adoption of RCS messaging.
