摘要: 针对现有量子密封拍卖协议中存在的报价隐私保护不够、恶意竞标者与第三方共谋等问题, 提出了一种基 于半量子安全直接通信的量子密封投标拍卖协议。该协议采用半量子安全直接通信, 通信时拍卖方仅需拥有测量 和反射粒子的能力; 通过对投标方报价的保序加密, 实现对报价的隐私保护; 利用隐私比较, 在无第三方参与的情 况下, 拍卖方也能比较保序加密后的报价信息。理论分析表明面对截获-重发、受控非门 (CNOT)、相位反转、共谋等 攻击时, 所提出协议仍具有较高的安全性, 且与同类型量子拍卖协议相比, 新协议通信效率不受投标人数的影响。

Abstract: 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.

Key words: quantum information, quantum auction, quantum sealed-bid auction, semi-quantum, order preserving encryption, private comparison
