Bidirectional user authentication and secret information quantum communication transmission method

Abstract

The invention discloses a bidirectional user authentication and secret information quantum communication transmission method, and relates to the technical field of quantum communication. By adopting the method, during the secret information transmission process, the assistance of a third party is not needed, and the secret information can transmitted safely from a sending end to a receiving end through just one transmission step, thereby simplifying the information transmission process. During an eavesdropping detection process, if an information sender does not know an identity identifier IDBof an information receiver, the eavesdropping detection cannot be passed; if the information receiver does not know the identity identifier IDA of the information sender, the information receiver cannot restore the secret information, namely, the identities of the information receiver and the information sender can be authenticated in the communication process, and the secret information is transmitted more safely. According to the method, a quantum memory and a unitary operator do not need to be configured, the sending end only needs to prepare the single photon and the Bell state particles,and the receiving end only needs to measure the single photon and the Bell state particles, so that the deployment cost is reduced, and the application of a quantum communication network is promoted.

Description

Technical field [0001] The present invention relates to the field of quantum communication technology, and in particular to a method for transmitting two-way user authentication and secret information quantum communication. Background technique [0002] In the field of communication technology, ensuring the security of secret information transmission is the most basic problem that needs to be solved for information security. [0003] Currently, users of both parties have the following shortcomings when transferring secret information: [0004] 1) In order to realize the transmission of secret information, both parties in communication need to obtain a secure key first, and then encrypt the information with the key, and realize the secure transmission of information through the form of the encrypted information. The operation is very complicated. [0005] 2) In order to realize the transfer of secret information between users of both parties, the assistance of a trusted third party is ...

AI Technical Summary

Problems solved by technology

[0004] 1) In order to realize the transmission of secret information, both parties need to obtain a secure key first, and then encrypt the information through the key, and realize the safe transmission of information by transmitting encrypted information. The operation is very complicated

[0005] 2) In order to realize the transmission of secret information between users of both parties, the assistance of a trusted third party is also needed, which increases the complexity of the scheme and increases the risk of secret information being eavesdropped

[0006] 3) In quantum communication, two-step transmission is generally required to realize the transmission of secret information, and the process is cumbersome;

[0007] 4) The existing secret information transmission method does not consider the issue of identity authentication, and only realizes the transmission of information from one end to the other, which has potential safety hazards

[0008] 5) In order to realize the safe transmission of information, the two sides of the communication need to configure expensive quantum devices, such as quantum memory, quantum unitary operator, etc., which is not conducive to the promotion and application of quantum communication networks
