- Abstract
In this paper, we propose a quantum sealed-bid auction (QSBA) protocol based on GHZ states and realize the simultaneous ascending auction scheme proposed by the 2020 Nobel Prize in economics. The protocol uses the trusted third-party Trent as a bridge between bidders and auction center to conduct multiple rounds of auctions. With the help of Trent, the auction center and bidders conduct controlled remote state preparation, so that the auction center can obtain all the bidding prices and publish them. The whole process is supervised by Trent, which not only ensures the trust between participants, but also effectively prevents the semi-honest auction center from disclosing the information of bidders. Trent is very important to the security of the whole protocol, so we assume that Trent is completely honest. In addition, we analyze the security and efficiency of the protocol, which proves that our protocol has high security and good efficiency. Therefore, this agreement is practicable.
