If the remailer does a good job with the delays and shuffling, then it becomes difficult for the analyst to match message a with message b, leaving him with what he already knew (that A and RemailerX have a common interest, as to B and RemailerX, but the interests may be wholly unrelated).
Nope. Not if each of them runs a remailer. That's why mixmaster is SO WONDERFUL.
The "to" and "from" values that the traffic analyst will be using are the IP addresses in the packets. It doesn't matter whether mixmaster, cypherpunks, or penet remailers are used, they still use IP addresses.
Sure *does* matter. There's no computationally feasible way to associate one mixmaster message with another. The only way you can get a clue is by analyzing who sends mail into and out of the mixmaster system. If both of your endpoints are within the mixmaster system, you have no entering or exiting mail to analyze. It doesn't matter if the mixmaster remailers are on the same or different systems. -russ <nelson@crynwr.com> http://www.crynwr.com/~nelson Crynwr Software | Crynwr Software sells packet driver support | PGP ok 11 Grant St. | +1 315 268 1925 voice | It's no mistake to err on Potsdam, NY 13676 | +1 315 268 9201 FAX | the side of freedom.
