An Equitably Fair On-line Auction Scheme
Abstract.
We present a sealed-bid electronic auction scheme that is equitably fair for the bidders and the seller. In this scheme, the interests of both the bidders and the seller are safeguarded: the identity of the non-winning bidders and their bidding behavior are protected (anonymity), and the bidders cannot withdraw their bids without being detected (non-repudiation). The scheme fulfills the requirements of a secure auction scheme and is verifiable. It extends the Stubblebine & Syverson auction scheme that is not equitably fair (it does not prevent bid withdrawals). Our scheme employs a Registrar and an Auctioneer for which no special trust assumptions are made.
