摘要
M+1价位拍卖是一种推广了的vickrey拍卖形式.为了克服信息泄露,提高安全性,文中利用多项式的秘密分享和Bit承诺技术,给出了一个新的安全的M+1价位电子拍卖方案.其特点是:易于实现,而且满足所有投标者身份匿名、所有投标者的标价保密、所有未中标者的个人信息不会被泄露等安全要求.
The (M+1)stprice auction is a kind of general Vickrey auction, and the secure schemes for the firstprice and the secondprice auction are not suitable for this kind of auction style because of the leakage of information. In this paper, we present a new secure (M+1)stprice auction scheme by modifying an existing firstrpice sealed bid scheme and combining the Bit commitment. The techniques used are simple, and the scheme can ensure that bidder anonymity (including the bidder corresponding to the (M+1)stprice bid), bid secrecy and no personal information about the losing bidder can be obtained.
