Abstract

This paper points out the risk of bid-rigging in electronic sealed-bid auctions and provides a receipt-free sealed-bid auction scheme to prevent it. The scheme enjoys receipt-freeness, secrecy of bidding price and public verifiability and uses a chameleon bit-commitment technique. It requires a bidding booth and a one-way untappable channel from eachbidding boothto each auctioneer.
