• Apple plans to integrate end-to-end encryption into RCS messaging on iPhones.
• It enhances security for cross-platform communication between Android and iPhone users.
• Apple alongside the GSM Association played a significant role in developing the RCS Universal Profile 3.0, which now includes encryption.

Apple has announced that it will add support for end-to-end encryption in RCS messaging on iPhones. This move, in collaboration with the GSM Association, brings RCS closer to iMessage in terms of security.

The latest RCS Universal Profile 3.0, which includes end-to-end encryption, was just released today. However, Apple hasn’t confirmed exactly when it will roll out this update to users. The company played a key role in leading a cross-industry effort to bring this security feature to the RCS Universal Profile.

Apple first introduced RCS support to iPhones with iOS 18.1 last fall. RCS improves messaging between iPhone and Android users by replacing traditional SMS with a more modern standard. It includes features like typing indicators, emoji reactions, read receipts, and support for higher-resolution photos and videos.

Until now, the RCS Universal Profile didn’t support end-to-end encryption, meaning messages sent through it weren’t as secure as those on iMessage. But with this new update, Apple has committed to integrating encryption into its ecosystem.

In a statement to 9to5Mac, Apple said, “End-to-end encryption is a powerful privacy and security technology that iMessage has supported since the beginning, and now we are pleased to have helped lead a cross industry effort to bring end-to-end encryption to the RCS Universal Profile published by the GSMA. We will add support for end-to-end encrypted RCS messages to iOS, iPadOS, macOS, and watchOS in future software updates.”

Meanwhile, reiterating commitment to secure messaging experience, Google said, “We’ve always been committed to providing a secure messaging experience, and Google Messages users have had end-to-end encrypted (E2EE) RCS messaging for years. We’re excited to have this updated specification from GSMA and work as quickly as possible with the mobile ecosystem to implement and extend this important user protection to cross-platform RCS messaging.”

Apple’s commitment to this update is a big step in improving the security of cross-platform messaging.

For those unfamiliar, end-to-end encryption ensures that only the sender and recipient can read messages. The decryption keys stay on users’ devices preventing any intermediaries from accessing the conversations. iMessage has had this level of security since its launch and now RCS messages will soon get the same protection.
