摘　　要：近年来,量子价格谈判(QPN)已成为量子密码中的热点研究问题,在电子商务领域有着广泛的应用前景。本文基于单光子和量子傅里叶变换,利用幺正操作将秘密的价格信息编码到d维单光子态的相位上,提出了一种新型多方量子价格谈判(MQPN)协议。分析表明,在半诚实第三方(TP)模型下,该协议在保证参与方隐私性的同时,可以有效抵抗外部和不诚实参与者(包括TP)的攻击,且具有更好的实用性。In recent years,quantum price negotiation(QPN)has become a hot research issue of quantum cryptography and has a wide application prospect in the field of e-commerce.In this paper,based on single photon and Fourier transform,a novel multi-party quantum price negotiation(MQPN)protocol is proposed by using unitary operation to encode secret price information into the phase of d-dimensional single photon state.The analysis shows that with the semi-honest third party(TP)model,the protocol can effectively resist external attacks and dishonest participants(including TP)attacks while ensuring the privacy of participants,and has better practicability.
