> I know nothing of the signal protocol, but whether the server can tell the message is garbage depends on what the receiver client tells the server. You're forgetting that the server is the one telling the sender what the new key is. If the key is under the control of the attacker/server, they can read the message and determine if it's garbage or not. |
