OSS video conferencing service 'Jitsi Meet' plans to support end-to-end encryption

Jitsi , which operates Jitsi Meet , an open source video conferencing service that allows video chats for free and without installation, says on its blog that it is testing end-to-end communication encryption with Jitsi Meet.

This is what end-to-end encryption should look like!

For communications involving a large number of people, such as video conferencing, WebRTC is used via a server called SFU , and Jitsi Meet implements SFU as Jitsi Videobridge (JVB). Although communication is encrypted on the network, it is necessary to decrypt the communication relayed by JVB, and there is a risk that the communication will be intercepted if JVB is allowed to access it.There is a problem with WebRTC encryption using SFU. It was a point.

End-to-end encryption (E2EE) solves this problem. WebRTC's E2EE can be implemented by simply adding encryption functionality to existing applications. It can be used by enabling ' Insertable Streams ', a function under development in the Chromium engine that allows data exchanged with WebRTC to be processed in a browser, and it will be possible for encrypted communication to pass through JVB as is. thing.

A movie that actually tested E2EE with Jitsi Meet has also been released.

PoC: end-to-end encryption in Jitsi Meet (Work in Progress) - YouTube


The screen shows three people having a fun conversation. These three people each have a key to encrypt the communication, so they can talk normally, but...

If the person on the bottom right who does not have the key participates, the encrypted communication cannot be decrypted, so the images of the other three people are noisy and it is not possible to talk.

When the person in the bottom right holds the key, they can now talk to the other three people.

Jitsi commented, 'End-to-end encryption is in progress to protect your Jitsi Meet communications. Stay tuned!'
