Wed. October 31 - Christopher Thorpe: Efficient, Secrecy-Preserving Proofs of Correctness for Electronic Commerce
The Center for Research on Computation and Society continues its weekly lunch seminar:
CRCS Privacy and Security Lunch Seminar
Date: Wednesday, 31 October 2007
Time: 12:00pm-1:00pm (Lunch Provided)
Place: Maxwell Dworkin119
Speaker: Christopher Thorpe, Harvard University
Topic: Efficient, Secrecy-Preserving Proofs of Correctness for Electronic Commerce
Abstract:
For many electronic commercial protocols, such as sealed- bid auctions, securities exchanges, and large “block” stock trades,
the information revealed and kept secret as part of the protocol is of extreme importance. We will explore recent advances in
cryptography that enable market and mechanism designers to precisely tune the transparency of their protocols to optimal economic requirements. We will consider examples such as sealed-bid auctions where no information is revealed to any bidder other than her own outcome and a stock trading protocol where traders post encrypted prices and/or quantities of their trades, and only information necessary for the efficient operation of the market needs to be revealed.
Joint work with David Parkes, Michael Rabin, and Stuart Shieber.
