【Abstract】 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.更多还原
