摘　　要：In recent years,with the development of blockchain,electronic bidding auction has received more and more attention.Aiming at the possible problems of privacy leakage in the current electronic bidding and auction,this paper proposes an electronic bidding auction system based on blockchain against malicious adversaries,which uses the secure multi-party computation to realize secure bidding auction protocol without any trusted third party.The protocol proposed in this paper is an electronic bidding auction scheme based on the threshold elliptic curve cryptography.It can be implemented without any third party to complete the bidding auction for some malicious behaviors of the participants,which can solve the problem of resisting malicious adversary attacks.The security of the protocol is proved by the real/ideal model paradigm,and the efficiency of the protocol is analyzed.The efficiency of the protocol is verified by simulating experiments,and the protocol has practical value.
