Problems solved by technology

Obviously, such a method increases the difficulty of link management, and also brings waste of resources
At the same time, in order to ensure security, authentication between devices is required every time a connection is created, and the communication can be successfully completed after multiple data and signaling interactions, which poses challenges to the carrying capacity of the network and the robustness of the software.

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples, but the protection scope of the present invention is not limited to the following specific examples.

[0044] Such as figure 1 As shown, a method for indirect communication of multiple quantum key management terminal devices, which reduces the links of multiple quantum key management terminal devices, reduces network complexity, and improves the robustness of the system. Through KMS (Key Management Server, Quantum Key Management Server) to establish connections with two KMs (Key Management Key Management Clients) to be communicated, there is no need to establish communication links of multiple KMs to realize the communication between two KMs. Indirect communication reduces the number of nodes through which the key plaintext passes, further improving security.

Abstract

The invention discloses a method for indirect communication of multiple pieces of quantum key management terminal equipment, which is characterized in that a quantum key management server (KMS) is respectively connected with two KMs to be communicated, and indirect communication between the two KMs is realized without establishing a communication link of multiple KMs. According to the invention, the number of communication links established in the network is reduced, the network complexity and the load of the whole network communication are reduced, and the robustness of the network is improved; as the number of nodes passed by the key plaintext is reduced, the security of the key is further improved.

Description

technical field [0001] The invention relates to the field of quantum secure communication, in particular to a method for indirect communication of a plurality of quantum key management terminal devices. Background technique [0002] Quantum communication is a new communication method that uses quantum superposition state and entanglement effect to transmit information, and it is a new interdisciplinary subject combining quantum physics and informatics. Benefiting from the rapid development of optical communication technology, photon-based quantum secure communication technology has gradually moved from theory to application, and has made great strides in the direction of engineering. Quantum secure communication can achieve theoretical absolute security, so it has attracted widespread attention from all walks of life. [0003] The main function of the quantum secure communication network is to realize symmetric key sharing between the two communicating parties. Because the...
