Quantum auction protocol based on semi-quantum secure direct communication
To address the issues of insufficient privacy protection of quotations and collusion between malicious bidders and third parties in existing quantum sealed auction protocols,a quantum sealed-bid auction protocol based on semi-quantum secure direct communication is proposed.Firstly,the protocol adopts semi-quantum secure direct communication,in which the auctioneer only needs to measure and reflect particles during communication.Secondly,the bidder can achieve the privacy protection of quotations through order-preserving transformation.Thirdly,the auctioneer can achieve privacy comparison of the transformed bid information without the participation of a trusted third party.Theoretical analysis shows that the proposed protocol is highly secured even facing attacks such as intercept-resend attack,control-NOT(CNOT)attack,phase inversion,and collusion attack.In addition,compared with the existing similar quantum auction schemes,the communication efficiency of the new protocol is not affected by the number of bidders.
