[Fisher Mark]

"An efficient Scheme for Proving a Shuffle", Crypto 2001, Jun Furukawa and
Kazue Sako (NEC Corporation), apparently could be used to show that a
remailer is processing all messages without revealing the header or contents
of any message.  (Apparently because I haven't read the paper -- just heard
of it on the nymip-res-group list.)
