摘要: 利用双线性对构造的数字签名具有安全性高、密钥长度短和实现快速等优点,为此通过双线性对构造一个指定验证者签名方案,给出其在招投标中的应用流程,通过理论分析证明该方案具有正确性、不可伪造性、不可否认性、不可传递性及签名源的隐匿性,并能防止招标公司为获得最低报价而采取的作弊行为。

Abstract: The digital signatures constructed by bilinear pairings have the advantages of higher security, short key size and high implementation speed This paper presents a new pairing based designated verifier signature scheme and through the theory analysis show that the scheme obtains the advantages of correctness, unforgeability, non-reputiation, non-transferable and signer-ambiguous. It can be applied in bidding and overcome the cheating of the bidding company to obtain the minimum quoting price.
