The Sixth International Financial Cryptography Conference was held during March 11-14, 2002, in Southampton, Bermuda. As is customary at FC, these proceedings represent "final" versions of the papers presented, revised to take into account comments and discussions from the conference. Submissions to the conference were strong, with 74 papers submitted and 19 accepted for presentation and publication. (Regrettably, three of the submit­ ted papers had to be summarily rejected after it was discovered that they had been improperly submitted in parallel to other conferences.) The small program committee worked very hard under a tight schedule (working through Christmas day) to select the program. No program chair could ask for a better committee; my thanks to everyone for their hard work and dedication. In addition to the refereed papers, the program included a welcome from the Minister of Telecommunications and e-Commerce, Renee Webb, a keynote address by Nigel Hickson, and a panel on privacy tradeoffs cheiired by Rebecca Wright (with panelists Ian Goldberg, Ron Rivest, and Graham Wood). The traditional Tuesday evening "rump session" was skillfully officiated by Markus Jakobsson. My job as program chair was made much, much easier by the excellent work of our general chair, Nicko van Someren, who performed the miracle of hiding from me any evidence of the innumerable logistical nightmares associated with conducting this conference. I have no idea how he did it, but it must have involved many sleepless nights.
