摘要： Previous bidirectional quantum private comparison (BQPC) protocols cannot meet the requirements in some special application scenarios, where only one party needs to obtain the comparison results without a third party (TP), such as scenarios for authority surveys or healthcare data sharing. In addition to this, the BQPC protocol has the potential of information leakage in multiple comparisons. Therefore, we design a new unidirectional quantum private comparison (UQPC) protocol based on quantum private query (QPQ) protocols with ideal database security and zero failure probability (IDS-ZF), for the reason that they have excellent unidirectionality and security. Concretely, we design a UQPC protocol based on Wei et al.'s work [IEEE Transactions on Computers 67 2 (2017)] and it includes an authentication process to increase the resistance to outside attacks. Moreover, we generalize the protocol and propose a general model that can transform a QPQ protocol with or without the IDS-ZF property into a secure UQPC protocol. Finally, our study shows that protocols using our model are secure, practical, and have the IDS-ZF property.
