A semi-quantum mutual identity authentication protocol based on GHZ state
Semi-quantum identity authentication plays a crucial role in ensuring communication security.By introducing a quantum third party to centrally manage keys,a new semi-quantum two-party authentication protocol based on Greenberger-Home-Zeilinger(GHZ)state is proposed.Firstly,the quantum capabilities of the participants are limited,both authenticators have only semi-quantum capabilities,and the protocol uses fewer quantum resources.Secondly,the two semi-quantum participants in the protocol only need to perform simple measurement operations and XOR operations.Through further security analysis,it is found that attacks such as impersonation attack,intercept-resend attack and entangle-measure attack cannot cause the leakage of legitimate identity information when using this protocol for quantum communication,indicating that the protocol can effectively prevent an illegal and dishonest participant from obtaining a legitimate identity,and has better security and practicality.
