An identity authentication method in the quantum key application process

Abstract

The invention discloses an identity authentication method during a quantum secret key application process. The identity authentication method includes the steps: a quantum network deployment phase, a preparation initial phase, a secret key preparation phase, an identity authentication phase and a secret key application phase. During an abstract extraction process, as the identity authentication method uses a quantum secret key and the quantum secret key is provided with true randomness, the difficulty for performing reverse operation on the abstract can be further reduced and the safety for information transmission can be improved; and at the same time, after accomplishment of one time of session identity authentication, only a device for identity authentication is allowed to apply for a secret key, so that the safety is further improved through verification of the device information, and during the process, a session ID is in continuous changing state and depends on a plurality of factors, so that a large amount of impersonation attack can be timely eliminated through verification of the session ID. For the identity authentication method during a quantum secret key application process, the secret key is applied to the quantum secret key application process to verify the legal identity between two parties for communication, so that verification of the legal identity of the opposite side between the two parties for communication can be realized and the required data for verification has absolute safety during the transmission process in the network.

Description

technical field [0001] The invention belongs to the field of quantum communication, and in particular relates to an identity authentication method in a quantum key application process. Background technique [0002] As human society enters into informatization, people communicate more and more frequently, people's demand for information is increasing day by day, and the acquisition and release of information has penetrated into everyone's daily life. But at the same time, various incidents of information leakage and illegal access to information continue to occur, which makes information security increasingly the focus of attention. [0003] Communication security is not only the primary concern of both communication parties, but also the most prominent security issue in the information society. Verifying the legal identity of both parties in communication is the first guarantee to ensure communication security. The existing identity authentication mechanism generally adopt...
