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)stprice auction is a kind of general Vickrey auction, and the secure schemes for the firstprice and the secondprice 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)stprice auction scheme by modifying an existing firstrpice 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)stprice bid), bid secrecy and no personal information about the losing bidder can be obtained.
