Well if you can get a handful of nodes between the sender and receiver you can start to narrow down on which peers are sending what to whom. This is partly the same sort of traffic analysis that is use against TOR.
- chongli 13y agoWhat? All peers receive all messages from everyone. There is no distinguishing senders and receivers.
- w-ll 13y agoNot at the exact same time they don't. You watch the propagation of the message.
- chongli 13y agoWhat does that tell you?
- fundamental 13y agoUnless I'm mistaken if you can see all the traffic a sender can be identified by being the first node to produce a set cyphertext. As the delays seem to be fairly short for the acknowledge messages, there is some chance that the receiver can be identified in a similar way. eg node A broadcasts C1 which has not been observed before nodes B,C,D propagate the cyphertext C1 node D broadcasts C2 shortly after receiving C1 nodes A,B,C propagate C2 etc Of course seeing this pattern in practice might be hard, but it still seems like a possible attack vector given the current system.
