Embodiment 1

[0073] Through the scheme of the above-mentioned specific implementation mode, the communication server and the CA server identity authentication process are provided as follows:

[0074] a. The communication server initiates an authentication request to the terminal, and sends the communication server ID and digital certificate C F sent to the terminal;

[0075] b. The terminal takes a random number R and sends it to the communication server;

[0076] c. The communication server signs the random number R and sends the signature result to the terminal;

[0077] d. Terminal with C F Verify the validity of the signature, and return the authentication result to the communication server. After the communication server passes the security authentication of the terminal, the two parties can transmit on-site transmission messages.

[0078] The two-way authentication process between the communication server and the base station is as follows:

[0079] a. After establishing a networ...

Abstract

The invention relates to a quantum encryption information transmission system, and the system comprises a first authentication module which is used for a communication server to send request information and authenticate the identity of a CA server; a second authentication module which is used for sending request information and identity authentication of the base station by the communication server; a remote interaction module which is used for generating a digital certificate application file of the CA server before the CA server is in a working state, importing a formal digital certificate stored in the database server into the CA server and executing remote transmission of quantum encryption information; and an updating module which is used for updating the symmetric key of the CA server before the CA server stops information transmission, and importing the test digital certificate stored in the communication server into the CA server. According to the scheme, the management process of the terminal digital certificate and the symmetric key is improved, the security protection loophole of the CA server in the quantum encryption information transmission process is made up, and therefore the security protection level of CA server field application and transmission is improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a quantum encryption information transmission system. Background technique [0002] At present, during the on-site transmission process of the CA server, the transmission personnel usually use portable devices to inspect the operation status of the terminal and maintain software functions. It is easy to be invaded, tampered with or even copied and simulated, forming security protection loopholes; secondly, the terminal cannot verify the legitimacy of the on-site communication server, and the internal data of the terminal is easily damaged by the illegal communication server; in addition, the digital certificate and symmetric key of the on-site CA server The management process is not perfect enough, which has a certain impact on the on-site deployment and application of the CA server. Contents of the invention [0003] Aiming at the above-mentioned security loophol...
