Abstract In view of the possible disclosure of personal information in the quantum auction protocol, by using the correlation between entangled particles and quantum teleportation, we propose a secure quantum sealed-bid auction (QSBA) protocol based on semi-honest model. In this protocol, by introducing a trusted third party Trent, we separate the registration operation of users from the business function of auction center. Bidders and the auction center can realize quantum identity authentication without information disclosure, so as to reduce the risk of the auction center disclosing the personal information of bidders. With the help of Trent, using the quantum sequences to be the information carrier of bidding, the auction center and bidders can conduct quantum teleportation to obtain each bidding price. When the auction center publishes the bid price and serial number, the registration center also publishes the corresponding winning bidder. Through security analysis, our protocol can guarantee the anonymity of bidders and the integrity of bidding information. Keywords Quantum sealed-bid auction · Entangle states · Quantum teleportation
1 Introduction Auction can be divided into two categories: public auction and sealed price auction. Public auction means that the whole auction process is open, and bidders can know the change of auction price, including British auction and Dutch auction. In the process of sealed price auction, the whole auction process is not publicized. An auction institution shall fully perform its duties as an auctioneer under the principles of openness, fairness and impartiality. The information of registered institutions is widely released, and the more bidders are attracted, the more the bidding function of the auction can be fully played, and the auction

agency, as a credible institution, announces the winning bidder. The bidders give their own bids at the beginning and submit them to the auctioneer in a sealed way, so the bidding situation among bidders is not known to each other. Compared with the public auction, the sealed price auction, including the first price sealed auction and the second price sealed auction, the first price sealed auction will be closer to the actual price, and it is a hot issue in recent years. The core of the sealed price auction is the “sealed”, which requires all bidders not to know what the other bidders are offering, so its implementation needs the help of cryptographic technology.
