[0002] With the development of intelligent power system, power feeder automation measurement and control devices play a key role in power grid monitoring and data collection. However, information security risks are becoming increasingly severe, traditional security measures are facing challenges, and the introduction of quantum secure communication technology has become a new direction to improve security.

[0003] The power feeder automation measurement and control device usually has a high power consumption when not performing encryption and decryption tasks, which conflicts with its long-term stable operation at the power grid site, partial reliance on battery power supply, and strict restrictions on energy consumption. Therefore, a low-power design scheme for power feeder automation measurement and control devices for quantum secure communication scenarios is needed. Summary of the invention

[0004] The present application is proposed based on the above-mentioned needs of the prior art. The technical problem to be solved by the present application is to provide a quantum secure communication component and its operation control method, so as to reduce the power consumption of the power feeder automation measurement and control device, reduce the power consumption impact of the wake-up process, improve the stability of the device operation, and improve the security of communication.

[0005] In order to solve the above problems, this application provides the following technical solutions.

[0006] The present application proposes a method for controlling the operation of a quantum secure communication component, comprising: step S11: setting a first independent circuit and a second independent circuit in the quantum secure communication component; step S12: connecting the quantum secure communication component to an automatic measurement and control device for power feeders to obtain power and transmit communication data; step S13: connecting the quantum secure communication component to a quantum secure communication device to transmit communication data; step S14: the quantum secure communication component generates a sleep instruction when no communication data is monitored, and generates a wake-up instruction when the communication data is monitored; step S15: the quantum secure communication component supplies power to the first independent circuit according to the sleep instruction, so that the communication function operates with low power consumption, and stops supplying power to the second independent circuit according to the sleep instruction, so that the encryption, storage, protocol conversion and analysis functions stop operating; step S16: the quantum secure communication component supplies power to the first independent circuit and the second independent circuit according to the wake-up instruction, so that the encryption, storage, communication, protocol conversion and analysis functions operate normally.

[0007] Furthermore, in the step S16, the encryption, decryption and storage functions are preferentially enabled to operate normally.

[0008] Furthermore, in the step S16, after the encryption / decryption and storage functions are operating normally, the communication function is preferentially operated normally.

[0009] Furthermore, it also includes step S17: the encryption and decryption, storage, communication, protocol conversion and analysis functions request data processing and storage resources; step S18: the quantum secure communication component preferentially allocates data processing and storage resources to the encryption and decryption and storage functions, and then allocates data processing and storage resources to the communication, protocol conversion and analysis functions.

[0010] Furthermore, the quantum secure communication component in the step S11 sets a third independent circuit, the quantum secure communication component in the step S15 stops supplying power to the third independent circuit according to the sleep instruction, so that the network monitoring and environment monitoring functions stop running, and the quantum secure communication component in the step S16 supplies power to the third independent circuit according to the wake-up instruction, so that the network monitoring and environment monitoring functions run normally.

[0011] Furthermore, in the step S16, after the encryption and decryption, storage, communication, protocol conversion and analysis functions are operating normally, the network monitoring and environment monitoring functions begin to resume normal operation.

[0012] Furthermore, the method further comprises step S19: the quantum secure communication component applies to the quantum secure device for a preset key for encrypting the quantum session key, and sets an update period of the preset key to be greater than an update period of the quantum session key.

[0013] The present application also proposes a quantum secure communication component, including a power module, a wake-up module, a main control board, a first independent circuit, a second independent circuit, a serial port module, a communication module, an encryption and decryption module, a storage module, a protocol conversion module and an analysis module, wherein the power input end of the main control board is electrically connected to the mainboard of the power feeder automation measurement and control device through the power module and the wake-up module, the power output end of the main control board is electrically connected to the first independent circuit and the second independent circuit, the serial port module and the communication module are arranged in the first independent circuit, the encryption and decryption module, the storage module, the protocol conversion module and the block analysis module are arranged in the second independent circuit; the communication module is communicatively connected to the quantum secure communication device, the serial port module is communicatively connected to the mainboard of the power feeder automation measurement and control device; the wake-up module The block monitors whether the serial port module and the communication module receive communication data; when the wake-up module does not monitor the communication data, the wake-up module generates a sleep instruction, the power module reduces the power output according to the sleep instruction, and the main control board supplies power to the first independent circuit according to the sleep instruction, so that the serial port module and the communication module run with low power consumption, and at the same time stops supplying power to the second independent circuit, so that the encryption and decryption module, the storage module, and the protocol conversion module stop running; when the wake-up module monitors the communication data, the wake-up module generates a wake-up instruction, the power module increases the power output according to the sleep instruction, and the main control board supplies power to the first independent circuit and the second independent circuit according to the wake-up instruction, so that the encryption and decryption module, the storage module, the communication module, the serial port module, the protocol conversion module, and the analysis module run normally.

[0014] Furthermore, when the main control board supplies power to the second independent circuit according to the wake-up instruction, the encryption and decryption module, the storage module, the communication module, and other modules resume normal operation in sequence.

[0015] Further, when the wake-up module generates a sleep instruction, the wake-up module operates with low power consumption according to the sleep instruction, and when the wake-up module generates a wake-up instruction, the wake-up module operates normally according to the wake-up instruction.

[0016] The beneficial effects of this application include:

[0017] (1) In the present application, the quantum secure communication component is provided with a first independent circuit and a second independent circuit, which can enter a sleep mode when not communicating, and only retain power to the first independent circuit where the communication function is located, so that the communication function can operate with low power consumption, thereby reducing the power consumption of the power feeder automation measurement and control device.

[0018] (2) During the wake-up process of the quantum secure communication component, the power supply of the encryption and decryption module and the storage module is restored first, so that the quantum secure communication component can quickly enter the working mode to perform encryption and decryption tasks and storage tasks, without being in the wake-up process for a long time when it cannot work normally. This improves the efficiency of the quantum secure communication component in performing tasks and further reduces the power consumption of the power feeder automation measurement and control device.

[0019] (3) The encryption and decryption functions and storage functions are restored to normal operation first, which can improve the reliability of encryption and decryption operations and storage operations, avoid encryption and decryption failures and data leakage caused by errors in the execution of encryption and decryption tasks and storage tasks, and improve the security of communications.

[0020] (4) The encryption and decryption functions and the communication functions are respectively arranged in the first independent circuit and the second independent circuit. The power supply partitions of the two independent circuits are independent of each other, thereby preventing the normal operation of the corresponding functions in the other independent circuit from being affected by the failure of one independent circuit or electromagnetic interference, thereby improving the reliability of the operation of the power feeder automation measurement and control device.

[0021] (5) Since the real-time requirements of tasks such as protocol conversion and analysis are lower, during the wake-up process of the quantum secure communication component, power can be preferentially transferred to encryption, storage, and communication functions, and power supply can be gradually restored in the order of encryption, storage, communication, and other functions, thereby reducing the power consumption impact of the wake-up process and improving the stability of the operation of the power feeder automation measurement and control device during the wake-up process.

[0022] (6) The quantum secure communication component can not only gradually restore the power supply of each function, but also allocate data processing and storage resources to each function in a corresponding order, so that each function can enter the working state in a stable order, avoiding system crashes caused by resource competition, and further improving the stability of the operation of the power feeder automation device during the wake-up process.

[0023] (7) The network monitoring and environmental monitoring functions are set in the third independent circuit. The power supply partitions of the third independent circuit and the other two independent circuits are independent of each other, which can effectively prevent the failure of the third independent circuit or electromagnetic interference from affecting the normal operation of key functions in the other two independent circuits, further improving the reliability of the operation of the power feeder automation measurement and control device.

[0024] (8) The real-time requirements of network monitoring, environmental monitoring and other tasks are much lower than those of encryption, storage, communication, protocol conversion and analysis tasks. Power and system resources can be given priority to key functions. After the key functions are running normally, the normal operation of network monitoring, environmental monitoring and other functions can be restored, thereby reducing the power consumption impact of the wake-up process and further improving the stability of the operation of the power feeder automation measurement and control device during the wake-up process.

[0025] (9) The update cycle of the preset key is longer than the update cycle of the quantum session key, which enables the quantum secure communication component to obtain more preset keys for encrypting the quantum session key at one time, without the need to frequently apply for and obtain preset keys from the quantum security service platform. This simplifies the encryption and decryption process, allowing the quantum secure communication component to complete tasks faster, thereby entering the sleep mode faster from the working mode, and further reducing the power consumption of the power feeder automation measurement and control device.

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0032] Example 1

[0033] like Figure 1 As shown, a quantum secure communication system includes a power feeder automation measurement and control device 100 and a quantum secure communication device.

[0034] The power feeder automation measurement and control device 100 is a power device, which is arranged at a key node of the power system external network, and is used to monitor the state of the feeder in real time, and perform control operations as needed to ensure the safe and stable operation of the power system. The power feeder automation measurement and control device 100 includes a quantum security communication component 200. The power feeder automation measurement and control device 100 obtains a quantum encryption function based on the quantum security communication component 200, so that it can receive a quantum session key, and call the quantum session key to encrypt and transmit the communication data such as fault inspection and monitoring collected by the power feeder automation measurement and control device 100 to the power system intranet, and can also call the quantum session key to decrypt the communication data encrypted and transmitted in the power system intranet.

[0035] The quantum security device includes a quantum security service platform 300, a quantum security gateway 400 and a distribution automation master station 500. Among them, the quantum security service platform 300 is a network security service platform, which is set in the power system intranet, and can generate and distribute quantum session keys and preset keys according to the request of the quantum security communication component 200 or other power equipment, and can also monitor the generation and distribution of quantum session keys and preset keys. The quantum security gateway 400 is a network security device, which is connected to the power feeder automation measurement and control device 100 through the external network and connected to the quantum security service platform 300 through the internal network. The quantum security gateway 400 is an entry device for the power feeder automation measurement and control device 100 to access the intranet. In order to ensure the security of communication, the quantum security gateway 400 also has a quantum encryption function, which enables the quantum security communication system to call the quantum session key to encrypt and transmit the communication data. The distribution automation master station 500 is set in the data center of the power system intranet. It can receive communication data decrypted by the quantum security gateway 400 located on the side of the distribution automation master station 500, and can also send communication data to the power feeder automation measurement and control device 100 through the quantum security gateway 400.

[0036] like Figure 2 As shown, in order to reduce the power consumption of the power feeder automation measurement and control device 100 when the encryption and decryption tasks are not performed, the present application proposes an operation control method of the quantum secure communication component 200, comprising the following steps:

[0037] Step S11: Setting a first independent circuit 204 and a second independent circuit 205 in the quantum secure communication component 200;

[0038] Step S12: Connect the quantum secure communication component 200 to the power feeder automation measurement and control device 100 to obtain power and transmit communication data;

[0039] Step S13: connecting the quantum secure communication component 200 to the quantum secure communication device to transmit communication data;

[0040] Step S14: the quantum secure communication component 200 generates a sleep instruction when no communication data is monitored, and generates a wake-up instruction when communication data is monitored;

[0041] Step S15: the quantum secure communication component 200 supplies power to the first independent circuit 204 according to the sleep instruction, so that the communication function operates with low power consumption, and stops supplying power to the second independent circuit 205 according to the sleep instruction, so that the encryption, storage, protocol conversion and analysis functions stop operating;

[0042] Step S16: The quantum secure communication component 200 supplies power to the first independent circuit 204 and the second independent circuit 205 according to the wake-up instruction, so that the encryption, storage, communication, protocol conversion and analysis functions can operate normally.

[0043] By setting the first independent circuit 204 and the second independent circuit 205 for the quantum secure communication component 200, the quantum secure communication component 200 can enter the sleep mode when there is no communication, and only keep the first independent circuit 204 where the communication function is located to power the communication function, so that the communication function runs with low power consumption, and at the same time stop the power supply to the second independent circuit 205, so that the encryption, storage, protocol conversion, analysis and other functions stop running, thereby reducing the power consumption of the power feeder automation measurement and control device 100. The quantum secure communication component 200 can also monitor the communication data in time and generate a wake-up instruction, and according to the wake-up instruction, the first independent circuit 204 and the second independent circuit 205 are powered, so that the quantum secure communication component 200 can quickly resume normal operation.

[0044] In addition, the encryption and decryption functions and the communication functions are respectively arranged in the first independent circuit 204 and the second independent circuit 205, and the power supply partitions of the two independent circuits are independent of each other, thereby avoiding the normal operation of the corresponding functions in the other independent circuit being affected by the failure of one of the independent circuits or electromagnetic interference, thereby improving the reliability of the operation of the power feeder automation measurement and control device 100.

[0045] In step S16, the quantum secure communication component 200 gives priority to the normal operation of encryption, decryption and storage functions.

[0046] As the core function of the quantum secure communication component 200, the encryption and decryption function always has the highest priority, whether it is data transmission or storage process. The storage function is responsible for storing important system files, key information, and user data. The execution of encryption and decryption tasks involves data storage and reading operations, and it is necessary to ensure the stability of the storage environment to avoid data loss or damage. Therefore, the priority of the storage function is second only to the encryption and decryption function.

[0047] During the wake-up process, the quantum secure communication component 200 gives priority to restoring the power supply of the encryption and decryption functions and the storage functions, so that the quantum secure communication component 200 can start to perform encryption and decryption tasks as soon as possible. When the encryption and decryption functions and the storage functions are running normally, the power supply of other functions can be restored. Accordingly, the quantum secure communication component 200 can give priority to executing encryption and decryption tasks and storage tasks with higher real-time requirements according to the urgency of the task to ensure that they can be processed quickly. For general data backup encryption and other tasks, they can be placed at the back end of the task queue and processed after the encryption and decryption tasks and storage tasks are completed.

[0048] When the encryption and decryption functions and the storage functions resume normal operation, the quantum secure communication component 200 can start to perform encryption and decryption tasks and storage tasks without being in a wake-up process where it cannot work normally for a long time. Therefore, the efficiency of the quantum secure communication component 200 in performing tasks can be improved, thereby reducing the power consumption of the power feeder automation measurement and control device 100.

[0049] In addition, the encryption and decryption functions and storage functions are restored to normal operation first, which can improve the reliability of encryption and decryption operations and storage operations, avoid encryption and decryption failures, data leakage, etc. caused by errors in the execution of encryption and decryption tasks and storage tasks, and improve the security of communications.

[0050] In step S16, after the encryption, decryption and storage functions are running normally, the communication function is prioritized to run normally.

[0051] The communication function is responsible for communicating with the power feeder automation measurement and control device 100, the quantum security service platform 300, and the quantum security gateway 400 to ensure smooth data transmission channels. When the quantum security communication component 200 is in sleep mode, the communication function is in a low-power listening mode, retaining only the function of detecting whether the communication data is received, and shutting down high-energy-consuming components such as the radio frequency power amplifier. When the encryption and decryption module 208 and the storage module 209 are operating normally, the quantum security communication component 200 gives priority to restoring the normal operation of the communication module 206 to ensure that the communication data is accurately and quickly delivered to the destination. Therefore, the priority of the communication function is second only to the encryption and decryption function and the storage function, and the faster the communication function is restored to normal operation, the more secure the communication can be further improved.

[0052] The protocol conversion function is responsible for converting the format of communication data. The communication data generated by the power feeder automation measurement and control device 100 is in serial port format. The protocol conversion function can convert the serial port format communication data received by the quantum security communication component 200 into IP format, thereby sending the IP format communication data through the IP network. The analysis function is mainly responsible for security analysis, integrity check and format verification of the received data, providing a basis for subsequent data processing, and can also conduct in-depth mining of past data to find potential safety hazards.

[0053] Since the real-time requirements of tasks such as protocol conversion and analysis are lower, power can be given priority to encryption, storage, and communication functions during the wake-up process of the quantum secure communication component 200. Compared with restoring normal operation of each function at the same time, gradually restoring power supply in the order of encryption, storage, communication, and other functions can reduce the power consumption impact of the wake-up process and improve the stability of the operation of the power feeder automation measurement and control device 100 during the wake-up process.

[0054] The operation control method of the quantum secure communication component 200 may also include step S17: the encryption and decryption, storage, communication, protocol conversion and analysis functions request data processing and storage resources, and step S18: the quantum secure communication component 200 preferentially allocates data processing and storage resources to the encryption and decryption and storage functions, and then allocates data processing and storage resources to the communication, protocol conversion and analysis functions.

[0055] Based on step S17 and step S18, the quantum secure communication component 200 can not only gradually restore the power supply of each function, but also allocate data processing and storage resources to each function in a corresponding order, so that each function can enter the working state in a stable order, avoiding system crashes caused by resource competition, and further improving the stability of the operation of the power feeder automation device during the wake-up process.

[0056] In this embodiment, the quantum secure communication system transmits communication data including the following steps:

[0057] Step S21: the quantum encryption communication group receives the communication data generated by the power feeder automation device;

[0058] Step S22: the quantum secure communication component 200 pre-stores a preset key;

[0059] Step S23: the quantum secure communication component 200 establishes a first transmission channel with the quantum secure service platform 300, the quantum secure communication component 200 applies to the quantum secure service platform 300 for a quantum session key and a preset key, the quantum secure service platform 300 calls the preset key based on the first transmission channel and encrypts the quantum session key, the quantum secure communication component 200 receives the encrypted quantum session key, and calls the pre-stored preset key to decrypt the encrypted quantum session key;

[0060] Step S24: the quantum security gateway 400 establishes a second transmission channel with the quantum security service platform 300, and the quantum security gateway 400 applies for and receives a quantum session key from the quantum security service platform 300;

[0061] Step S25: The quantum secure communication component 200 uses the decrypted quantum session key to encrypt the communication data;

[0062] Step S26: The quantum security gateway 400 receives the encrypted communication data and uses the quantum session key to decrypt the encrypted communication data;

[0063] Step S27: The distribution automation master station 500 receives the communication data decrypted by the quantum security gateway 400.

[0064] In step S23, the quantum secure communication component 200 needs to frequently apply to the quantum security service platform 300 for a preset key for encrypting the quantum session key. In order to further reduce power consumption, the operation control method of the quantum secure communication component 200 also includes step S19: the quantum secure communication component 200 applies to the quantum security service platform 300 for a preset key for encrypting the quantum session key, and sets the update period of the preset key to be greater than the update period of the quantum session key. Since the update period of the preset key is greater than the update period of the quantum session key, the quantum secure communication component 200 can obtain more preset keys for encrypting the quantum session key at one time, without frequently applying for and obtaining preset keys from the quantum security service platform 300, thereby simplifying the encryption and decryption process, enabling the quantum secure communication component 200 to complete the task faster, thereby faster entering the sleep mode from the working mode, and further reducing the power consumption of the power feeder automation measurement and control device 100.

[0065] like Figure 1 and Figure 3 As shown, the present application also proposes a quantum secure communication component 200, including a power module 201, a wake-up module 202, a main control board 203, a first independent circuit 204, a second independent circuit 205, a communication module 206, a serial port module 207, an encryption and decryption module 208, a storage module 209, a protocol conversion module 210 and an analysis module 211.

[0066] In this embodiment, the main board of the power feeder automation measurement and control device 100 is electrically connected to the power input end of the power module 201 to obtain power and output stable voltage and current. The power output end of the power module 201 is electrically connected to the wake-up module 202, and the wake-up module 202 can monitor whether the serial port module 207 and the communication module 206 of the quantum secure communication component 200 receive communication data, generate a sleep instruction when the communication data is not monitored, and generate a wake-up instruction when the communication data is monitored. The power input end of the main control board 203 is electrically connected to the wake-up module 202, and the power output end of the main control board 203 is electrically connected to the first independent circuit 204 and the second independent circuit 205. The main control board 203 can receive the sleep instruction and the wake-up instruction, and dynamically adjust the output voltage of the power module 201 and the power supply status of the first independent circuit 204 and the second independent circuit 205 according to the sleep instruction and the wake-up instruction. The serial port module 207 and the communication module 206 are arranged in the first independent circuit 204, and the encryption and decryption module 208, the storage module 209, the protocol conversion module and the block analysis module 211 are arranged in the second independent circuit 205. The quantum security communication component 200 realizes the communication function through the serial port module 207 and the communication module 206. The serial port module 207 is connected to the main board of the power feeder automation measurement and control device 100 for communication, and the communication module 206 is connected to the quantum security service platform 300 and the quantum security gateway 400 for communication.

[0067] When the wake-up module 202 does not monitor the communication data, the wake-up module 202 generates a sleep instruction, the power module 201 reduces the power output according to the sleep instruction, the wake-up module 202 runs at low power consumption according to the sleep instruction, and the main control board 203 supplies power to the first independent circuit 204 according to the sleep instruction, so that the serial port module 207 and the communication module 206 run at low power consumption, and the power module 201 stops supplying power to the second independent circuit 205 according to the sleep instruction, so that the encryption and decryption module 208, the storage module 209, and the protocol conversion module 210 stop running. When the wake-up module 202 monitors the communication data, the wake-up module 202 generates a wake-up instruction, the power module 201 increases the power output according to the wake-up instruction, and the wake-up module 202 resumes normal operation according to the wake-up instruction. At the same time, the main control board 203 supplies power to the first independent circuit 204 and the second independent circuit 205 according to the wake-up instruction, so that the encryption and decryption module 208, the storage module 209, the communication module 206, the serial port module 207, the protocol conversion module 210 and the analysis module 211 resume normal operation in sequence.

[0068] In addition, different modules of the quantum secure communication component 200 are optimized and integrated using software algorithms to avoid repeated occupation of system resources and reduce resource conflicts at the software level.

[0069] Example 2

[0070] Embodiment 2 provides another quantum secure communication component 200 and its operation control method. The difference from Embodiment 1 is that in order to ensure that the key functions such as encryption and decryption, storage, communication, protocol conversion and analysis can operate stably and reliably during the wake-up process, functions such as network monitoring and environmental monitoring can be set in independent circuits different from the key functions.

[0071] In this embodiment, the quantum secure communication component 200 is configured as follows: Figure 4 As shown in the third independent circuit 212, the quantum secure communication component 200 can stop supplying power to the third independent circuit 212 according to the sleep instruction, so that the network monitoring module 213 and the environment monitoring module 214 stop running. The quantum secure communication component 200 can also supply power to the third independent circuit 212 according to the wake-up instruction, so that the network monitoring module 213 and the environment monitoring module 214 run normally.

[0072] By setting the network monitoring and environmental monitoring functions in the third independent circuit 212, the power supply partitions of the third independent circuit 212 and the other two independent circuits are independent of each other, which can effectively prevent the failure of the third independent circuit 212 or electromagnetic interference from affecting the normal operation of key functions in the other two independent circuits, thereby improving the reliability of the operation of the power feeder automation measurement and control device 100.

[0073] When the quantum secure communication component 200 is in the wake-up process, after the encryption and decryption, storage, communication, protocol conversion and analysis functions are running normally, the network monitoring and environment monitoring functions begin to resume normal operation.

[0074] The real-time requirements of tasks such as network monitoring and environmental monitoring are much lower than those of encryption, storage, communication, protocol conversion and analysis tasks. Power and system resources can be given priority to key functions, and the normal operation of network monitoring, environmental monitoring and other functions can be restored after the key functions are operating normally, thereby reducing the power consumption impact of the wake-up process and further improving the stability of the operation of the power feeder automation measurement and control device 100 during the wake-up process.

[0075] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
