Description

Technical Field

[0001] The present invention belongs to the technical field of quantum terminal communication, and relates to a terminal communication interaction system based on electric power quantum communication technology. Background Art

[0002] Power line terminal communication usually refers to a way of using power lines as a transmission medium for data communication. Power quantum communication technology is a new communication technology that uses the principles of quantum mechanics to transmit information. It uses quantum states as information carriers to achieve information encryption, transmission and decryption. In power systems, this technology can be applied to terminal communications to improve the security and efficiency of data transmission. In the process of power line terminal communication, the security and efficiency of quantum communication are important components of the communication process analysis. Therefore, the study of terminal communication interaction based on power quantum communication technology is of great significance.

[0003] The existing analysis of the power line terminal communication process usually only involves the separate analysis of communication security and efficiency, ignoring the comprehensive analysis of communication security and communication efficiency. This analysis process ignores the inherent connection and mutual influence between the two. This analysis method lacks a global perspective and cannot fully evaluate the overall performance of the communication system. The power system communication environment is complex and changeable, including electromagnetic interference, network attacks and other threats. It is often difficult to cope with these complex environments by analyzing communication security or efficiency alone.

[0004] The existing power line terminal communication process analysis usually only involves the compliance analysis of communication security and efficiency, and lacks the automated processing of abnormal situations. This analysis method not only weakens the communication system's ability to respond quickly to failures, reduces the overall reliability and stability of the system, but also increases the complexity and cost of operation and maintenance. At the same time, it also hinders the development of the power system to a higher level of intelligence and limits the potential of data-driven decision-making and intelligent management. Summary of the invention

[0005] In view of this, in order to solve the problems raised in the above background technology, a terminal communication interaction system based on power quantum communication technology is proposed.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1 As shown, the present invention provides a terminal communication interaction system based on electric power quantum communication technology, the system includes a quantum key distribution security analysis module, a quantum channel security analysis module, a quantum entanglement degree anomaly analysis module, a communication path security analysis module, a communication path efficiency analysis module, a communication path replacement demand judgment module and a data storage library, wherein the quantum key distribution security analysis module, the quantum channel security analysis module and the quantum entanglement degree anomaly analysis module are all connected to the communication path security analysis module, the communication path security analysis module and the communication path efficiency analysis module are connected to the communication path replacement demand judgment module, and the data storage library is connected to the communication path efficiency analysis module and the communication path replacement demand judgment module.

[0020] The quantum key distribution security analysis module is used to monitor the security of the quantum key distribution process of the target communication path, obtain the quantum key distribution process security data corresponding to the target communication path, and analyze the quantum key distribution security of the target communication path.

[0021] In a preferred embodiment of the present invention, the quantum key distribution process security data includes the key generation rate, the quantum bit error rate and the detector noise anomaly.

[0022] It should be noted that the reasons for selecting key generation rate, quantum bit error rate and detector noise anomaly as security data in the quantum key distribution process are: 1. The key generation rate determines how fast the quantum key distribution system can generate secure keys. In practical applications, a higher key generation rate means that the key can be updated more frequently, thereby reducing the risk of the key being cracked. 2. The quantum bit error rate reflects the probability of transmission errors in the quantum channel. In the process of quantum key distribution, bit errors may be caused by various factors, such as noise, interference, and eavesdropping. If the quantum bit error rate is too high, it may mean that there are security risks in the channel or that the system has been attacked. 3. The detector noise anomaly can help detect potential eavesdropping attacks. In quantum key distribution, eavesdroppers may obtain key information by interfering with the detector. This interference will cause the detector noise to increase abnormally.

[0023] In a preferred embodiment of the present invention, the analysis of the quantum key distribution security of the target communication path requires constructing a quantum key distribution security index of the target communication path, and the specific method is as follows: extracting the key generation rate, quantum bit error rate and detector noise anomaly corresponding to the target communication path, which are recorded as KGr, QEr and NAd respectively.

[0024] It should be noted that the key generation rate and quantum bit error rate can be collected using a quantum communication comprehensive tester.

[0025] It should be added that the analysis process of the detector noise abnormality is as follows: the detector noise of the quantum detector is obtained by using a spectrum analyzer, and then the detector noise abnormality is obtained by performing a difference calculation with a preset reference detector noise.

[0026] It should be explained that the detector noise in the present invention refers to the false counts generated by the detector when there is no actual quantum signal input.

[0027] Using the formula The quantum key distribution security index λ of the target communication path is obtained by analysis 1 , where KGr 0 Indicates the preset reference key generation rate, QEr 0 Represents the preset reference quantum bit error rate, NAd 0 represents the preset detector noise anomaly threshold, α 1 , α 2 , α 3 They respectively represent the weight factors corresponding to the preset key generation rate, quantum bit error rate and detector noise anomaly.

[0028] It should be noted that the weight factors corresponding to the key generation rate, quantum bit error rate and detector noise anomaly are set based on the following: 1. If the security requirements for communication are extremely high, the weight of the key generation rate should be relatively high. Because a higher key generation rate means that the key can be updated more frequently, reducing the risk of the key being cracked. 2. If the quality of communication is strictly required, such as in the fields of scientific research data transmission, medical image transmission, etc., it is necessary to ensure the accuracy and integrity of the data, then the weight of the quantum bit error rate should be higher. 3. If the detector has good performance and high stability, the noise anomaly is usually low, and its weight can be relatively low at this time.

[0029] For example, α 1 =0.3, α 2 =0.3, α 3 =0.4.

[0030] The quantum channel security analysis module is used to monitor the quantum channel security of the target communication path, obtain quantum channel security data corresponding to the target communication path, and analyze the quantum channel security of the target communication path.

[0031] In a preferred embodiment of the present invention, the quantum channel security data includes channel loss rate and channel transmittance.

[0032] It should be noted that the reasons for choosing channel loss rate and channel transmittance as quantum channel security data are: 1. The channel loss rate can intuitively reflect the attenuation degree of quantum signals during transmission. In quantum communication, higher channel loss will reduce the strength of the signal, making it difficult for the detector at the receiving end to accurately detect the quantum state, thereby increasing the bit error rate and security risks. 2. Channel transmittance reflects the transmission capacity of the quantum channel for signals, that is, what proportion of quantum signals can successfully pass through the channel to the receiving end. High transmittance means that the channel has less interference with the signal and can better maintain the integrity of the quantum state. In quantum communication, anti-interference ability is one of the key factors to ensure communication security.

[0033] It should be noted that the channel loss rate and channel transmittance can be collected using a spectrum analyzer.

[0034] In a preferred embodiment of the present invention, the analysis of the quantum channel security of the target communication path requires constructing a quantum channel security index of the target communication path, and the specific method is as follows: extracting the channel loss rate and channel transmittance corresponding to the target communication path, which are recorded as CLr and Ct respectively.

[0035] Using the formula The quantum channel security index λ of the target communication path is obtained by analysis 2 , where CLr 0Indicates the preset channel loss rate threshold, Ct 0 Indicates the preset reference channel transmittance, β 1 , β 2 They respectively represent the weight factors corresponding to the preset channel loss rate and channel transmittance, and e represents a natural constant.

[0036] It should be noted that the weight factors corresponding to the channel loss rate and channel transmittance are set based on the following: From the perspective of communication needs, in scenarios with high security requirements, in order to ensure interference-free transmission of signals, the channel transmittance weight factor is relatively high. General demand scenarios require comprehensive consideration. In terms of communication distance, the channel loss rate weight factor increases over long distances due to increased losses. In complex environments, the channel transmittance weight factor will increase due to the large impact of the environment. From the perspective of system performance, high-performance systems can reduce the channel loss rate weight factor by means of error correction and enhancement technology. Low-performance systems are significantly affected by losses, so the channel loss rate weight factor is relatively high. Reasonable setting of weight factors helps optimize the performance and security of quantum communication systems and adapt to the needs of different application scenarios.

[0037] For example, β 1 =0.65, β 2 =0.35.

[0038] The quantum entanglement degree anomaly analysis module is used to use a quantum entanglement detector to collect the quantum entanglement degree of the target communication path corresponding to the communication process in real time, and then analyze the quantum entanglement degree anomaly of the target communication path.

[0039] It should be noted that the quantum entanglement degree is a physical quantity that describes the degree of entanglement in a quantum entangled system. In quantum mechanics, when two or more quantum systems are in an entangled state, their states cannot be described independently, but are described by an overall quantum state. The quantum entanglement degree reflects the closeness of this entanglement.

[0040] It needs to be further explained that quantum entanglement plays a core role in quantum key distribution. A higher degree of quantum entanglement can greatly improve the security of key distribution. When the sender and receiver share a pair of highly entangled quantum states, any eavesdropping by a third party will inevitably destroy the entanglement. This is because according to the principles of quantum mechanics, the measurement of a quantum state changes its state. If an eavesdropper tries to measure the quantum state in transmission to obtain key information, detectable interference will be introduced, which will be detected by both communicating parties. A higher degree of quantum entanglement means it is more difficult to eavesdrop, thereby enhancing the security of quantum communication.

[0041] In a preferred embodiment of the present invention, the analysis of the quantum entanglement abnormality of the target communication path requires the construction of a quantum entanglement abnormality index of the target communication path, and the specific method is as follows: extracting the quantum entanglement of the target communication path corresponding to the communication process collected in real time by a quantum entanglement detector, and then drawing a quantum entanglement change curve of the target communication path with time as the horizontal coordinate and quantum entanglement as the vertical coordinate.

[0042] It should be explained that the reasons for drawing the curve of quantum entanglement change of the target communication path are: 1. The security of quantum communication depends to a large extent on the degree of quantum entanglement. By drawing the curve of quantum entanglement change, the dynamic changes of quantum entanglement on the communication path can be monitored in real time. If the quantum entanglement suddenly drops within a certain period of time, it may mean that the communication path is subject to external interference or potential security threats, such as interference from eavesdroppers. 2. Continuous observation of the quantum entanglement change curve can also help determine the stability of the communication system. If the curve fluctuates greatly, it means that the communication environment is unstable, and it may be necessary to further optimize the communication system or take additional protective measures.

[0043] A number of monitoring points are evenly arranged on the target communication path quantum entanglement degree change curve based on equal interval lengths. The vertical coordinate corresponding to the monitoring point is marked as the monitored quantum entanglement degree, and the horizontal coordinate corresponding to the monitoring point is marked as the monitoring time.

[0044] The vertical coordinate corresponding to the initial moment of the target communication path quantum entanglement degree change curve is marked as the reference quantum entanglement degree.

[0045] The monitored quantum entanglement degrees are compared to obtain the maximum quantum entanglement degree and the minimum quantum entanglement degree, and the maximum quantum entanglement degree and the minimum quantum entanglement degree are respectively compared with the reference quantum entanglement degree to obtain the maximum quantum entanglement degree deviation index and the minimum quantum entanglement degree deviation index, and then the difference calculation is performed to obtain the monitored quantum entanglement degree deviation index.

[0046] Obtain the slope corresponding to each monitoring point of the target communication path quantum entanglement degree change curve, compare the absolute values ​​of the slopes corresponding to each monitoring point, and drill out the maximum slope absolute value as the monitoring quantum entanglement degree fluctuation index.

[0047] The quantum entanglement degree deviation index and the quantum entanglement degree fluctuation index are monitored and summed according to the weights to obtain the quantum entanglement degree anomaly index of the target communication path.

[0048] It should be noted that the basis for setting the corresponding weights of the monitoring quantum entanglement deviation index and the monitoring quantum entanglement fluctuation index is as follows: In quantum communication, the setting of the corresponding weights of the monitoring quantum entanglement deviation index and the fluctuation index needs to consider the communication security requirements and communication quality requirements. In scenarios with high security requirements, the weight of the deviation index may be higher because any slight change in quantum entanglement may imply a security risk. The fluctuation index also needs to be considered to ensure communication stability. In general security requirement scenarios, the weights can be adjusted according to actual conditions, and the weight of the deviation index can be appropriately reduced when more attention is paid to efficiency and cost. In scenarios with high communication quality requirements, if the system has high requirements for stability, the weight of the fluctuation index can be appropriately increased. In scenarios with low communication quality requirements, the weight of the fluctuation index can be reduced. In short, it is necessary to comprehensively consider various factors to reasonably set the weights to ensure the security and stability of quantum communication.

[0049] Exemplarily, the corresponding weights for monitoring the quantum entanglement degree deviation index and monitoring the quantum entanglement degree fluctuation index are 0.45 and 0.55 respectively.

[0050] The communication path security analysis module is used to analyze the communication security of the target communication path based on the quantum key distribution security, quantum channel security and quantum entanglement abnormality of the target communication path.

[0051] It should be explained that the reasons for selecting quantum key distribution security, quantum channel security and quantum entanglement anomaly as factors affecting the communication security of the target communication path are: quantum key distribution is the key to ensuring the security of information encryption, and its security directly determines whether encrypted communication can resist attacks. Quantum channels are the medium for signal transmission. Channel loss, transmittance and other factors affect signal quality and security. Bad conditions may lead to information leakage or errors. Abnormal quantum entanglement will destroy the correlation of quantum states, reduce the anti-interference ability and confidentiality of communication, and affect the safe communication distance. Comprehensive consideration of these three factors can comprehensively and effectively evaluate and ensure the quantum communication security of the target communication path, allowing quantum communication to play a more reliable role in various fields.

[0052] In a preferred embodiment of the present invention, the analysis of the communication security of the target communication path requires constructing a communication security index of the target communication path, and the specific method is as follows: extracting the quantum key distribution security index, quantum channel security index and quantum entanglement anomaly index of the target communication path.

[0053] Using the formula The communication security index λ of the target communication path is obtained by analysis, where ζ represents the quantum entanglement abnormality index of the target communication path, γ 1 , γ 2 , γ 3They respectively represent the weight factors corresponding to the pre-set quantum key distribution security index, quantum channel security index and quantum entanglement degree anomaly index.

[0054] It should be noted that the weight factors corresponding to the quantum key distribution security index, quantum channel security index and quantum entanglement anomaly index are set based on the following: When setting the weight factors corresponding to the quantum key distribution security index, quantum channel security index and quantum entanglement anomaly index, it is necessary to consider the communication scenarios and requirements, technical characteristics and reliability, as well as risk assessment and prevention strategies. In scenarios with high security requirements, the weight of the quantum key distribution security index may be higher, the quantum channel security index cannot be ignored, and the weight of the quantum entanglement anomaly index is relatively low. In general security requirement scenarios, it is necessary to balance the weights of the three indexes, and appropriate adjustments can be made when more attention is paid to efficiency and cost. At the same time, technical factors such as the maturity of quantum key distribution technology, quantum channel characteristics, and the stability of quantum entanglement also affect the weight setting.

[0055] For example, γ 1 =0.35,γ 2 =0.35,γ 3 =0.3.

[0056] It should be noted that the present invention conducts a comprehensive analysis from multiple aspects, including quantum key distribution security, quantum channel security, and quantum entanglement abnormality, when conducting security analysis of the communication process. This analysis method is not only based on the scientific principles of quantum mechanics, ensuring the accuracy and rigor of the analysis, but also has foresight and practicality, and can foresee and respond to potential security threats, providing strong security guarantees for the practical application of quantum communication technology. At the same time, the method can also timely discover and warn of potential security risks in the communication process, ensuring the stable operation of the communication system and data security.

[0057] The communication path efficiency analysis module is used to monitor the communication efficiency of the target communication path, obtain communication efficiency data corresponding to the target communication path, and analyze the communication efficiency of the target communication path.

[0058] In a preferred embodiment of the present invention, the communication efficiency data includes a magnetic induction intensity evaluation index, a power line integrity index and a power line length.

[0059] It should be noted that the reasons for selecting the magnetic induction intensity evaluation index, power line integrity index and power line length as communication efficiency data are as follows: 1. The magnetic induction intensity evaluation index reflects the impact of the surrounding magnetic field environment on communication. The appropriate magnetic induction intensity helps to ensure the stable transmission of communication signals and avoid the decrease in communication efficiency due to magnetic field interference. 2. The power line integrity index reflects the state of the power line itself. High integrity means fewer line failures and stable and reliable signal transmission, which can provide good infrastructure support for communication, thereby improving communication efficiency. 3. The length of the power line is directly related to the degree of signal attenuation and transmission time. A shorter line length usually means lower signal loss and faster transmission speed, which is conducive to improving communication efficiency.

[0060] It should be supplemented that the analysis method of the magnetic induction intensity evaluation index is as follows: a number of collection points are evenly arranged on the target communication path based on equal intervals, and the magnetic induction intensity of each collection point is obtained by using a magnetic induction intensity monitoring device. The magnetic induction intensity of each collection point is respectively calculated by difference with the preset reference magnetic induction intensity to obtain the magnetic induction intensity deviation value corresponding to each collection point, and the absolute value of the magnetic induction intensity deviation value corresponding to each collection point is calculated by ratio with the preset reference magnetic induction intensity to obtain the magnetic induction intensity deviation degree corresponding to each collection point, and then the average calculation is performed to obtain the monitoring magnetic induction intensity deviation degree, which is recorded as Bi.

[0061] Substitute the monitored magnetic induction intensity deviation Bi into the formula The magnetic induction intensity evaluation index Biei of the target communication path is obtained by analysis, where Bi 0 Indicates the preset reference magnetic induction intensity.

[0062] It should be added that the analysis method of the power line integrity index is as follows: a high-definition camera is used to capture the physical protection layer image of the target communication path, and then image processing software is used to obtain the length corresponding to each defect position in the physical protection layer image of the target communication path, and the length corresponding to each defect position is accumulated and calculated to obtain the monitored defect length, which is recorded as qL.

[0063] Using the formula The power line integrity index PLei of the target communication path is obtained by analysis, where qL 0 Indicates the preset target communication path length.

[0064] In a preferred embodiment of the present invention, the analysis of the communication efficiency of the target communication path requires constructing a communication efficiency index of the target communication path, and the specific method is as follows: extracting the magnetic induction intensity evaluation index, power line integrity index and power line length of the target communication path, which are recorded as Biei, PLei and L respectively.

[0065] Using the formula The communication efficiency index η of the target communication path is obtained by analysis, where L 0 Indicates the preset reference power line length.

[0066] For example, L 0 =20km.

[0067] The communication path replacement demand judgment module is used to judge whether there is a communication anomaly in the target communication path based on the communication security and communication efficiency of the target communication path, and if so, further identify the specific anomaly direction, which includes communication security anomaly and communication efficiency anomaly. If the specific anomaly direction is communication efficiency anomaly, identify the appropriate communication path and then replace the communication path.

[0068] In a preferred embodiment of the present invention, the specific method of determining whether there is a communication anomaly in the target communication path is as follows: extracting the communication security index and communication efficiency index of the target communication path, and then substituting them into the analysis model Get the communication anomaly index φ of the target communication path, where λ 0 represents the preset communication security index threshold, η 0 represents the preset communication efficiency index threshold, ∧ represents the logical relationship, max[] represents the maximum value, and min[] represents the minimum value.

[0069] It should be added that the communication security index threshold and the communication efficiency index threshold are set based on the following: 1. For the communication security index threshold, the importance and sensitivity of the communication content must be considered. At the same time, potential security risks, including the possibility of external attacks, technical vulnerabilities, etc., must be combined to determine a security index threshold that can effectively prevent risks. 2. For the communication efficiency index threshold, the real-time requirements, business needs, and cost-effectiveness of communication must be considered. In addition, the technical capabilities and resource limitations of the communication system must also be considered. On the premise of ensuring security, the communication efficiency index threshold should be reasonably set to achieve a balance between security and efficiency.

[0070] For example, 0 =0.95,η 0 =0.8.

[0071] The communication anomaly index of the target communication path is compared with a preset communication anomaly index threshold. If the communication anomaly index of the target communication path is greater than the communication anomaly index threshold, it is determined that there is a communication anomaly in the target communication path. Otherwise, it is determined that there is no communication anomaly in the target communication path.

[0072] Exemplarily, the communication anomaly index threshold is 0.2.

[0073] It should be noted that the present invention conducts a comprehensive analysis of communication security and communication efficiency when analyzing the quantum communication process. This analysis method can take into account both ensuring the security of data transmission and improving the operating efficiency of the communication system, achieving dual optimization of security and efficiency, and providing a more comprehensive and effective solution for the practical application of quantum communication technology.

[0074] In a preferred embodiment of the present invention, the specific method of identifying a specific abnormality is as follows: extracting the communication security index and communication efficiency index of the target communication path, and then comparing them with a preset communication security index threshold and a communication efficiency index threshold, respectively.

[0075] If the communication security index of the target communication path is less than the communication security index threshold, it is determined that the abnormality of the target communication path is directed to a communication security abnormality.

[0076] If the communication efficiency index of the target communication path is less than the communication efficiency index threshold, it is determined that the abnormal direction of the target communication path is abnormal communication efficiency.

[0077] It should be noted that the specific abnormality may point to one or both of communication security abnormality and communication efficiency abnormality.

[0078] In a preferred embodiment of the present invention, the specific method of identifying a suitable communication path is as follows: obtain the starting position and the end position corresponding to the target communication path, obtain several monitoring paths between the starting position and the end position, and analyze the communication efficiency index corresponding to each monitoring path.

[0079] It should be noted that there may be several communication paths between any starting point and end point.

[0080] It should be noted that the analysis of the communication efficiency index corresponding to each monitoring path refers to the specific method of analyzing the communication efficiency of the target communication path.

[0081] The communication efficiency indexes of the monitoring paths are compared, and the monitoring path corresponding to the maximum communication efficiency index is selected as the appropriate communication path.

[0082] It should be noted that the present invention further identifies the specific abnormal direction and performs automatic path adjustment when judging that a communication abnormality occurs. This analysis method not only significantly improves the fault response speed and self-repair capability of the communication system, but also can effectively reduce the losses caused by communication interruption or failure, ensuring the continuity, stability and efficiency of the communication process, and providing a more reliable and intelligent guarantee for the practical application of quantum communication technology.

[0083] The data storage library is used to store the path distribution diagrams corresponding to the starting point and the end point of the target communication path.

[0084] The above contents are merely examples and explanations of the concept of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.
