摘要
利用基于双线性对的W群签名,提出了一个新的密封式电子拍卖方案.与以往基于群签名技术提出的同类方案相比该方案不但满足电子拍卖的安全性要求,而且在用户加入群时不需要交互式零知识证明,并且具有签名短、步骤简略、签名验证简单等特点.
With the help of group signature based on bilinear pairing,a new sealed-bid electronic auction scheme is presented. Compairing with the former auction schemes based on group signatures,the new one not only satisfies all main properties of common secure public auction schemes,but also have some other characteristics： don’t need identification and signature when the user take part in the group,the short of length,compendiary steps,easily to verify,ect.
