Meanwhile, with the continuous development of the operation management work of the national power grid company, various internet +' novel business modes are continuously emerged, the information internal and external network environments are more complex, the connection with the internet is increasingly tight, and the communication information also faces severe safety threats. In addition, with the improvement of high-performance computing power, the traditional security encryption mechanism based on the national security algorithm also faces the risk of being cracked.
The quantum secret communication technology takes Quantum Key Distribution (QKD) as a core, based on a quantum unclonable principle, realizes unconditional safe communication among users in a one-time pad mode through a quantum communication protocol of single-photon signals, and greatly improves the safety level of a communication transmission network. Fig. 1 is a block diagram of a prior art quantum secure communication system. As shown in fig. 1, the quantum secure communication system is mainly composed of quantum key terminals (Alice and Bob) and a quantum encryption/decryption terminal. The working principle of the system is as follows:
the quantum secret communication technology mainly realizes the safe key distribution between two communication parties by utilizing the principle characteristics that a single photon is not divisible and a quantum state is not reproducible, solves the safety problem of key distribution in a symmetric encryption algorithm and realizes the safe encryption communication of transmission data. In fig. 1, a quantum key terminal Alice is responsible for generating a single photon quantum signal, and a quantum key terminal Bob is responsible for receiving the single photon quantum signal through a quantum channel. The quantum key terminal Alice and the quantum key terminal Bob carry out interactive negotiation through a negotiation channel to jointly generate a quantum key, and the keys are respectively stored in 2 terminals. When data are transmitted, the quantum encryption terminal extracts the secret keys from the quantum secret key terminal Alice request in order, then the data are encrypted, one secret key is obtained at a time, the encrypted ciphertext is transmitted to the quantum decryption terminal through a classical channel, according to a quantum communication protocol mechanism, the quantum secret key terminal Bob provides the secret keys for the quantum decryption terminal to decrypt the data, and finally the safe transmission of the data is achieved.
At present, based on the security of the quantum secure communication technology, related researchers propose to apply the quantum secure communication technology in the power industry, that is, a quantum communication system is used for transmitting power grid related data, so that the security of a power grid communication network is improved. However, the technology still stays in a theoretical level and is not applied to practical application, mainly because the electric power optical fiber line carrying the quantum channel has great complexity, and the electric power communication network has the remarkable characteristics of many communication sites, large space distance span, long overhead optical cable line, complex line electromagnetic environment and the like. Therefore, the application of the quantum secure communication technology in the hybrid power communication network has great uncertainty, and the quantum signal is greatly influenced by the communication medium and internal and external factors, so how to apply the quantum secure communication technology in the power grid communication network still lacks relevant data support and test verification, which is a problem to be solved urgently by those skilled in the art.

It should be noted that the electric power quantum communication system in this document is the same as the existing quantum secure communication system, and the specific structure can be referred to in the prior art, but the quantum secure communication system is herein combined with the electric power industry to transmit the electric power service information.
The transmission medium used by the quantum channel can adopt an overhead single-mode optical fiber/single-mode power communication optical cable fiber core and the like. Because the transmission distance of the transmission medium is very far and is easily influenced by the external environment, how to apply the quantum secret communication system to the power industry needs early test work, thereby providing data support for subsequent practical application.
Therefore, in this embodiment, a plurality of types of test cases are set according to the power grid environment parameters, where the test cases are the real environments where the simulated power quantum communication system is located. The test sample can generate the quantum key after being processed by the quantum key terminal in the power quantum communication system. And after receiving a test request of a user, selecting a target test case according to the test request. It is understood that the target test case is one of the test cases, and herein, for the sake of distinction only, any test case may become the target test case.
After the above configuration is completed, the power quantum communication system is controlled to start, that is, the power quantum communication system generates a corresponding quantum key for the test sample under the target test case to perform quantum key encryption transmission of the power service information, and then records the communication result of the power quantum communication system, that is, records the test result. Corresponding test results are provided for various test cases, so that the influence of the external environment on a quantum channel in the power quantum communication system can be obtained, and a real reference basis is provided when the quantum communication system is set. It should be noted that, if a fault occurs during the test, the cause of the fault and the related test result also need to be recorded. And, every time a test case is tested, necessary cleaning work is needed so that the subsequent test result is not affected.
The method for testing the polarization code rate of the electric power quantum secret communication system comprises the steps of presetting various types of test cases related to power grid environment parameters; checking a test environment and a test sample, and selecting a target test case according to a test request after receiving the test request of a user; and controlling the power quantum communication system to generate a corresponding quantum key for the test sample under the target test case so as to carry out quantum key encryption transmission of power service information, and recording a test result. The method aims to overcome the problems of complex power communication networking, large environmental factor interference and the like by setting various types of test cases, and carries out quantum signal performance test work of the quantum secret communication system under the simulated power grid environment, thereby realizing the test of the running condition and various performance indexes of the quantum secret communication system under the power grid environment and verifying the feasibility and the safety of the quantum secret communication system applied to the power grid service.
The invention fully considers various transmission losses, climatic weather environment, electromagnetic field and other factors existing in the actual operation of the electric power quantum secret communication system, and designs a communication distance attenuation loss test case, a galloping loss test case, a quantum channel line connection loss test case, a lattice type vibration loss test case, a polarization correlation loss test case, an electromagnetic interference loss test case and/or a temperature loss test case which comprise quantum channels. Hereinafter, a plurality of test cases will be described separately. It is to be understood that the plurality of test cases are only some of the plurality of test cases, and are not representative of only the plurality of test cases. The polarization type is a quantum signal source modulation method, which generates a quantum signal of a single photon by modulation, and generally modulates a polarization state signal of light by controlling a polarization controller through a circuit. The test method of the present invention is based on polarization.
