To solve these problems, a quantum sealed-bid auction protocol based on quantum homomorphic message authentication is proposed. This protocol introduces a semi-honest third party with certain malicious behavior as the intermediary and verifier, which is responsible not only for transmitting information between the bidders and the auctioneer, but also for verifying the auction results after they are announced to ensure fairness and impartiality of the auction. In the protocol, before sending a bid, the bidder needs to first send the encrypted bid commitment to the third party, which will process it and then send it to the auctioneer. The auctioneer who receives the information will verify the identities of the bidders, confirm the source of the information, decrypt the information and finally use the results to determine whether someone has tampered with the bid during the auction process. The application of quantum homomorphic message authentication scheme and the introduction of a semi-honest third party in the auction process can not only avoid collusive attacks, but also effectively protect the privacy of bidders. %U https://journal.bupt.edu.cn/EN/abstract/article_5325.shtml
