n.asokan,valtteri.niemi Abstract. We argue that threshold trust is not an option in most of the reallife electronic auctions.We then propose two new cryptographic Vickrey auction schemes that involve, apart from the bidders and the seller , an auction authority so that unless and collude the outcome of auctions will be correct, and moreover, will not get any information about the bids, while will learn bid statistics. Further extensions make it possible to decrease damage that colluding and can do, and to construct ? st price auction schemes. The communication complexity between the and in medium-size auctions is at least one order of magnitude less than in the Naor-Pinkas-Sumner scheme., |
