Sealed-bid Electronic Auction Scheme Based on Group Signature

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.
