from the extra-private-email dept.
Several years ago I heard a very good talk on
at Defcon. These provide significant enhancements over encrypted mail and other attempts at private communications by thwarting traffic analysis, for example. Since then, I have had an interest in anonymous communications, particularily anonymous remailers. When I was just starting on the net anon.penet.fi (if I recall correctly) was the big site devoted to this. Since then, a whole host of more robust systems have been brought up.
