A Secure Electronic Auction Scheme Based on Group Signature
Tang Wenliang · Jisuanji fangzhen · 2010
The paper studies the group signature based on bilinear pairing,and a new secure electronic auction scheme is designed based on the group signature.The scheme is based on bilinear pairing with vector space secret sharing and subliminal channel.It uses vector space secret sharing mechanism to ensure the anonymity of the bidder,and the open process to confirm bidder is realized by subliminal channel.Analyses show that under the same security conditions,the length of public key in the scheme is independent and the length of the signature is much shorter than other one constructed by other measure.Furthermore,the scheme is suitable for large scale distributed aution.So this scheme is secure and efficient secret sharing scheme.
