摘要：

In this paper, the cryptanalysis about the quantum sealed-bid auction, whose feature is that by introducing a postconfirmation mechanism the malicious bidders cannot collude with auctioneers, is given. We found that a malicious bidder can obtain the other bidders' bids with a probability of 0.854. Moreover, there will be a higher probability if some bidders collude to attack the other bidders' bids. To prevent such attacks, we propose an effective improvement by means of the hash function.
