Abstract:

To reduce the complexity of post-confirmation mechanism, achieve mutual identity authentication and improve the security of the protocol, a new effective and secure quantum sealed-bid auction protocol is proposed. The protocol introduces the bulletin board mechanism to replace the post-confirmation mechanism. It can ensure the fairness of the protocol by each bidder publishing classical committed information, instead of sending the secret bid to other bidders. Furthermore, it can verify correctness of the protocol, i.e., the cheater can be found if the auction is unfair. In addition, this protocol takes use of the principle of entanglement swapping based on Bell states to complete bidirectional identity authentication and bidding. Compared with other related protocols, this protocol reduces the communication complexity of the post-confirmation mechanism and provides the identity authentication of both the sender and the receiver. Therefore, the efficiency and the security of this protocol are improved.

Key words: quantum sealed-bid auction, entanglement swapping, post-confirmation, bulletin board
