Google has begun rolling out end-to-end encryption for Rich Communication Service, the text-messaging standard the industry giant is pushing as an alternative to SMS.
Abbreviated as RCS, Rich Communication Service provides a, well, richer user experience than the ancient SMS standard. Typing indicators, presence information, location sharing, longer messages, and better media support are key selling points. They lead to things like better-quality photos and videos, chat over Wi-Fi, knowing when a message is read, sharing reactions, and better capabilities for group chats.

Google said on Thursday that it has now completed its worldwide rollout of RCS and is moving to a new phase—end-to-end encryption. Interest in end-to-end encryption has mushroomed over the past decade, particularly with revelations from Edward Snowden of indiscriminate spying of electronic communications by the NSA.
End-to-end encryption is the antidote to such snooping. It uses strong cryptography to encrypt messages with a key that’s unique to each user. Because the key is in sole possession of each user, end-to-end encryption prevents everyone else—including the app maker, ISP or carrier, and three-letter agencies—from reading a message. Messaging apps that currently provide E2EE include Signal, WhatsApp, and iMessage, to name just three.
Now, Google wants to join the club. For now, E2EE will be available only to people using the beta version of the Android Messages app.
