Signal adds group video calls up to 40 people and end-to-end encrypted -!

Signal, the veteran messaging app that recently gained traction with the “crisis” of WhatsApp’s new privacy policy, added group video calls from up to five people a year ago. Now the application supports video calls up to 40 participants.

Signal was a little late for group calls, but the wait was worth it. The application now supports group video calls up to 40 people with end-to-end encryption , thus beating the bet of for example WhatsApp.

Encrypted group video calls

There are many applications to make group video calls, but if we add the end-to-end encryption to the equation the list is reduced. This type of encryption poses a series of technical difficulties when implementing encryption, and the Signal team has been working to find a feasible solution, as detailed in their blog.

Signal has opted for an SFU (Selective Forwarding Unit) architecture, by which each participant sends the streaming to a server , which forwards it to each participant without viewing or altering it, but no solutions already available were scaling correctly for large numbers of participants. As a consequence, Signal has created its own implementation from scratch using Rust.

After nine months in testing, Signal is already satisfied enough with this implementation to activate it for users. Thus arrive the group video calls with up to 40 participants without problems, to such an extent that it is possible that in the future the number could increase even more.

Signal now supports 32 person group calls. Building large end-to-end encrypted group calls required some new engineering. Learn how we did it here: https://t.co/i15 rRqkI4l
