| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Vickrey auction, in which the highest bidder wins at the second highest price, is a well-known incentive compatible auction. For achieving the privacy of bidders, we can run the auction without revealing the bidding prices to bidders, while it allows the auctioneer to cheat the second highest bidding price. In this paper, we propose making use of the techniques of secret sharing, and design an information-theoretically secure protocol that prohibits auctioneers from cheating the bidders, and that does not leak any additional information against the set of size $t < n/2$ semi-honest bidders, i.e., $t$-private, where $n$ is the number of the bidders. Apart from conventional methods, bidders run the protocol by themself, and thus it does not require third parties for secret sharing. Another strong point is that, in case we have two or more highest bids, our protocol breaks the tie with equal probabilities without revealing any information. |
