The GSM Association (GSMA) has announced a formally support for end-to-end encryption (E2E) to secure messages sent through the rich communication services (RCS) protocols, which provided a lot of necessary safety safety safety for the cross-platform messages shared between Android and iOS platforms.
By that end, the new GSMA specifications for RCS include the E2 EE based on the messaging layer security (MLS) protocol through the RCS Universal Profile 3.0.
GSMA Technical Director Tom Wan Pelt said, “The new specifications defined how to implement MLS in the context of RCS.” “These procedures ensure that messages and other materials such as files remain confidential and safe as they travel among customers.”
This also means that in the near future, RCS will be the first “mass message service” to support interoperabled E2E between various customer implementation from various providers.
It is worth noting that Google’s own implementation of RCS is used in the message app for Android, the underlying E2EE protects the interaction by using a signal protocol to overcome the lack of security. The encryption saforgard is currently limited to the messages made through the app, not exchanging with those who are exchanged with users or users of other RCS clients on Android, “said that said.
GSMA stated that it is working towards implementing End-to-end encryption (E2E) to secure messages sent between Android and iOS ecosystems, it comes after about six months. The move followed Apple’s decision to roll out support for RCS in its own message app with iOS18.
In July 2023, Google revealed that it intends to add support to MLS in its message service and to add the open-source implementation of the specification.
“RCS continues to support a series of inter-derable messaging functions between iOS and Android users, such as group messaging, the ability to share high-resolution media, and read receipts and typing indicators,” supports a series of interopeable messaging functions. ,
When arrived for the comment, Google said, “We are always committed to providing a safe message experience, and Google Messages is the end-to-end encrypted (E2E) RCS messaging to the users. We encourage this updated specifications from GSMA to GSMA and work quickly with the mobile ecosystem and quickly work with the mobile ecosystem and quickly work to increase this important user protection with the mobile ecosystem. To cross the RCS. “
