I am reminded of this paper: "The Cocaine Auction Protocol: On the Power of Anonymous Broadcast" Frank Stajano and Ross Anderson Traditionally, cryptographic protocols are described as a sequence of steps, in each of which one principal sends a message to another. It is implicitly assumed that the fundamental communication primitive is necessarily one-to-one, and protocols addressing anonymity tend to resort to the composition of multiple elementary transmissions in order to frustrate traffic analysis. This paper builds on a case study, of an anonymous auction between mistrustful principals with no trusted arbitrator, to introduce "anonymous broadcast" as a new protocol building block. This primitive is, in many interesting cases, a more accurate model of what actually happens during transmission. With certain restrictions it can give a particularly efficient implementation technique for many anonymity-related protocols. http://www-lce.eng.cam.ac.uk/~fms27/cocaine/ -- "Acquaintance, n.: A person whom we know well enough to borrow from but not well enough to lend to." --Ambrose Bierce // seth gordon // [EMAIL PROTECTED] // http://ropine.com/sethg/cv.html // _______________________________________________ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
