可公开验证的安全电子拍卖方案

在大多数电子拍卖方案中,如果第三方勾结,那么投标者的标价不再保密。在任何情况下保持标价的秘密性是非常重要的,它们很可能是投标者重要的商业秘密。该文提出了一种可公开验证的安全电子拍卖,结合零知识证明协议,使拍卖方案可公开验证并达到最小泄漏。该方案泄漏的只是中标价,其余标价及其相互关系在任何勾结情况下都是保密的,而且,标价的正确性可以公开验证。该方案的效率远远高于最近Brandit提出的方案。

Publicly Verifiable Secure Electronic Auction

In the most of existing electronic auctions, the bidders' bids no longer remain confidential if the third parts collude. However, keeping the bids secret in any case is vital to the bidders because these evaluations may be their critical commercial secrets. This paper proposes a publicly verifiable secure electronic auction meeting such requirements. The only leakage is the selling price while the other bids and their relation keep confidential in any collusion. The scheme is more efficient than the recently proposed scheme due to Brandit.
