Revocation of trust is always a tricky issue, you can look at TLS certificates to see what a can of worms that is. The Signal server does not forward messages to your devices, and …

About the paper: if someone has gotten access to your identity (private) key, you are compromised, either with their attack (adding a linked device) or just getting MitM'ed and all…

I don't think they are insane, they are quite useful when designing security mechanisms, while at the same time being utter noise for the end-user benefiting from that system. > If…

I would also read it from another perspective. Attackers, especially at the level of nation states, will always try to get as many avenues for achieving their goals as possible. If…

Your phone (primary device) and the linked ones have to share the IK since that is the "root of trust" for you account: with that you generate new device keys, renew them and so on…

That's not what the attack does tho - they have access to your private key so they can complete the linking protocol without your phone and add as many devices as they want (up to …

The attack in that paper assumes you have compromised the user's long term private identity key (IK) which is used to derive all the other keys in the signal protocol. Outside of l…
