GCHQ pushes for backdoors in encrypted chat apps
- londons_explore 8y agoI would like this approach. Third party apps would soon appear to detect these 'extra' participants in conversations - after all, your device has to know about every party in a chat to be able to encrypt the messages for all of them. When a user can run a third party app and see if they are being watched or not, that gives the government a significant risk of being 'spotted'. Thats probably enough risk that they decide to use the technique on very few people. It could backfire though if the government decides to add themselves to everyones conversations, users use the third party app and see they are being spied on, but the press and public aren't interested enough to demand a stop to it.
- contravariant 8y agoWouldn't a man-in-the-middle design make more sense? That would still be detectable but it's far from easy to do. I have to admit I'm not sure how silently Whatsapp and the like could essentially force a 'reset' that would allow the man-in-the-middle attack to take place, but generally it's not too unusual for a protocol to get out of sync and require renegotiation.
