In order to prevent the collusion between an auctioneer and the bidders, a novel quantum sealed-bid auction protocol with the help of a trusted third-party center is proposed, which adopts quantum authentication and quantum public key with single particles. In this protocol, the honest and trusted third-party center first issues a pseudonym for each bidder, further generates the public and private keys for the auctioneer, and finally verifies the legitimacy of the winning bid announced by auctioneer. This protocol only needs single particles and a limited number of entangled Bell states, which can effectively reduce quantum resources. Compared with the previous proposed protocols, our proposed protocol has higher security properties and better feasibility.
