Apple is set to introduce support for encrypted Rich Communication Services messaging between iPhone and Android users, thanks to new updates in RCS specifications. This change, announced by the GSM Association, will enable end-to-end encryption based on the Messaging Layer Security protocol, marking a significant advancement in secure messaging across platforms. Apple spokesperson Shane Bauer highlighted the company’s role in this cross-industry effort, stating that support for encrypted RCS messages will be included in future updates for iOS and other operating systems. Previously, while Apple’s iMessage system offered encryption, RCS messaging lacked the necessary cross-platform support. Google has also provided end-to-end encryption for RCS messages among its users for several years and is eager to expand this security feature to cross-platform messaging.
Why do we care?
Many businesses still rely on SMS or unencrypted RCS for communication with employees, vendors, and customers. The adoption of end-to-end encryption in RCS will significantly enhance security for cross-platform business messaging, reducing exposure to man-in-the-middle attacks and SMS interception. This is an area where providers can distinctly help.
