Actually, the odds are better than this, .8^5, about 0.33. You will be compromised "only" 1/3 of the time.
But if you are sending regular messages to another party, then traffic analysis will quickly show that you are communicating, because even if the boys at Langley are really dumb, you won't make send more than two or three messages without having all the cherries lining up.
You will be protected if you have encrypted your messages, but using a remailer network offers little additional protection.
I am not sure I see why you think that the "cherries" will line up.
Remember that the original assumption was that you were choosing five remailers at random, on each transmission. I argue against this strategy; I think that if you know someone is reliable you should stick with them. 80% of the remailers are compromised, so 2/3 of single messages get through OK, 45% of two message sequences, 30% of three message sequences, etc. If a population of users selects five remailers at random and sticks to their initial selection, 1/3 of the population will be compromised immediately. Langley will have to try harder to get the rest. -- Jim Dixon

I'm not sure what other people think of the "trustworthiness" of various remailers, but when chaining I usually bounce it through two, AND the first leg goes offshore to hacktic which seems superably reliable. After that, it goes to either wimsey or ghio. Be better to hacktic and then another Euro-mailer before going back to North America, but what other European remailers are as reliable as hacktic? -----BEGIN PGP SIGNATURE----- Version: 2.6 iQCVAgUBLkuF9UyJS+ItHb8JAQGm7gP/QgHjySdT3++zHdkkZkWpC9SsyUyuHAW+ GZQcalGGmN71xdO8hk+UY5IEAPYUYDBqfRdUq0eVGdariQU50LbEoH7W2sSEmupF 9LjxAZUq95kLxAqLvt97O6qb/KZcVdZrja3WIeuLTYohxGESZZdD1VKtmV9D9ghA cIOBkUjR4wc= =rAxK -----END PGP SIGNATURE-----
