[0010] Further, both the calling end and the called end apply for session keys through the quantum security audio and video command platform.

[0011] Further, the calling end directly sends the encrypted service data to the called end.

[0012] Further, it also includes a quantum security audio and video command platform for allocating session IDs and session keys to the built-in audio and video background.

[0013] Further, the quantum key is deprecated after being used only once and is updated in real time.

[0014] The beneficial effects of the present invention:

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] Please refer to Figures 1 to 2 , the present invention provides the following technical solutions: an audio and video command system based on quantum key technology, which integrates quantum key technology to protect intercom, media sharing, and dispatching information with high-level encryption, providing stable and reliable quantum security intercom services for end-users of various mainstream brands.

[0021] In this embodiment, the quantum key technology is integrated through a multi-functional audio and video intelligent platform to form a comprehensive and coordinated linkage video communication command platform that combines rapid response, peacetime and wartime integration, high-definition video, un-delayed communication, strong command, and resource guarantee. Intercom, media sharing, and dispatching information are all protected by high-level encryption. The operation process of this system is as follows:

[0022] In this embodiment, as Figure 1 shown, it includes access terminals, command platform Z, and a quantum security service base. More terminals can be accessed according to actual needs. In this embodiment, terminals A, B, and C are provided for illustration.

[0023] Terminals ABC and command platform Z are network-authenticated to the quantum security service base. Before audio and video communication, the session keys of both communication parties are securely distributed through the quantum security base. The audio and video communication between terminals ABC and between the terminals and command platform Z can be encrypted and protected through the session keys distributed by the quantum security service base, thus realizing quantum encrypted communication between end-to-end and end-to-multi-end.

[0024] This embodiment also provides a usage method of the system provided in the above embodiment. Refer to Figure 2As shown in the figure, where the quantum-secure audio and video command platform is the command platform Z + quantum-secure service base in the above example, the specific steps are as follows:

[0025] The terminal initiates the injection of the secret key into the security medium in A.

[0026] The terminal A initiates a call as the calling end.

[0027] The terminal A performs network access authentication.

[0028] The terminal B initiates the injection of the secret key into the security medium in B.

[0029] The terminal B initiates a call as the calling end.

[0030] The terminal B performs network access authentication.

[0031] A session is negotiated and established between the terminal A and the terminal B.

[0032] The terminal A applies for a session secret key from the quantum-secure audio and video command platform according to the session ID vector.

[0033] The terminal B applies for a session secret key from the quantum-secure audio and video command platform according to the session ID vector.

[0034] The terminal A calls the encryption interface to encrypt the service data.

[0035] The terminal A sends the encrypted service data to the terminal B.

[0036] The terminal B receives the encrypted service data.

[0037] The terminal B calls the decryption interface to decrypt the service data.

[0038] Moreover, the communication between the terminal and the platform is similar to the above, and the platform itself will also allocate a session ID and a session secret key to the built-in audio and video background.

[0039] Through the above audio and video command system, the security problems of traditional public network intercom, such as the clear text transmission and storage of audio, video, Beidou positioning and other streaming media data, the inability to authenticate intercom terminals, and the lack of security encryption compliant with national cryptography, are solved. The one-time-one-key for intercom services such as single call, group call, and real-time video is realized. The quantum key is discarded after use and updated in real time, providing users with a stable and reliable quantum-secure intercom service.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0041] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
