利用椭圆曲线离散对数问题的难解性,给出了基于椭圆曲线密码体制(elliptic curve cryptosystems)的可验证、安全、高效、密封的M+1价位电子拍卖方案。除了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外,还能抗击恶意投标者对正常拍卖进行的破坏。
By means of the intractability of ellipse curve discrete logarithm problem, this paper presented a verifiable, security, efficacious and secret M + I st-price electronic auction scheme based on elliptic curve cryptosystems. The scheme not only can ensure that bidder anonymity, bid-price secrecy and no personal information about the losing bidder can be obtained but also can prevent the Malicious bidder from destroying the auction.
