DETAILED DESCRIPTION

[0021] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that various forms of implementing the present disclosure should not be limited by the embodiments set forth herein. On the contrary, the embodiments are provided to more thoroughly understand the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0022] Please refer to Figure 1 As shown, the present application provides a power terminal access method, which is applied to a satellite communication network, and the satellite communication network includes a pseudo-spoofing device.

[0023] like Figure 2 and Figure 3 As shown, the pseudo-spoofing device is located between the power equipment and the satellite communication network.

[0024] The power terminal access method comprises the following steps: S101. Determine the power protocol type of the power terminal.

[0025] Power protocols are standardized protocols used for data exchange and information communication in power systems, such as IEC60870-5-101 / 104, DNP3, etc.

[0026] like Figure 2 As shown, the power protocol type received by the fake deception device.

[0027] In actual applications, power terminals adopt different power protocols according to their network environment and configuration.

[0028] In the "power protocol" processing stage, the received protocol data is analyzed to understand its key characteristics such as format, encoding method, communication protocol, etc. Through analysis, the type of power protocol currently used by the power terminal is determined.

[0029] Once the power protocol type is determined, the corresponding subsequent processing is performed according to the type.

[0030] S102: Configure the communication interface of the pseudo-spoofing device according to the power protocol type.

[0031] Identify the type of power protocol followed by the connected power terminal.

[0032] According to the identified power protocol type, the communication interface of the fake deception device is configured accordingly, including setting the correct communication parameters (such as baud rate, data bit, stop bit, check mode, etc.), protocol stack configuration (such as message format, command set, etc.), and the required encryption / decryption algorithm configuration (if required by the protocol or in order to improve communication security).

[0033] After the configuration is completed, the communication interface of the fake deception device is verified for compatibility to ensure that it can seamlessly connect with the power terminal in accordance with the requirements of the power protocol. Specifically, it involves sending test messages, receiving response messages, and verifying the correctness and integrity of the messages.

[0034] Since there are many different types of power protocols in the power system, the fake deception device should have the ability to dynamically adjust its communication interface configuration. This means that it should be able to automatically or manually adjust the configuration of its communication interface according to the different protocol types used by the connected power terminals to adapt to different communication environments and requirements.

[0035] When configuring the communication interface of the pseudo-spoofing device, consider the security of the communication process. In particular, when configuring the encryption / decryption algorithm, ensure that the algorithm used is strong enough to resist potential attacks and eavesdropping risks. In addition, measures should be taken to protect the pseudo-spoofing device itself from being controlled or tampered with by malicious attackers.

[0036] Furthermore, in order to improve efficiency and reduce human errors, the communication interface configuration process of the fake deception device can be automated and intelligent. For example, the power protocol type can be automatically identified and the communication interface parameters can be configured through a software program; or artificial intelligence technology can be used to optimize the configuration process and improve the adaptability and stability of the system.

[0037] S103: formulating a simulation strategy for the pseudo-spoofing device according to the communication interface, including a sending frequency of heartbeat data and a simulation logic of a response message.

[0038] Conduct a detailed analysis of the communication interface between the power terminal and the communication network, including: understanding the interface type (such as serial port, network port, etc.), communication protocol (such as Modbus, IEC60870-5-104 and other power protocols), data format and interaction process.

[0039] Based on the analysis of the communication interface, the pseudo-spoofing device formulates a set of simulation strategies to achieve effective deception of the power terminal, including: simulating the normal communication behavior between the power terminal and the communication network, so that the communication network mistakenly regards the pseudo-spoofing device as a legitimate power terminal.

[0040] Determination of the frequency of sending heartbeat data: Heartbeat data is a signal that the power terminal sends to the communication network periodically to maintain the active state of the communication link and confirm the online status of the terminal. The fake deception device needs to formulate a corresponding sending strategy based on the actual heartbeat data sending frequency of the power terminal to ensure that the communication network will not detect anomalies due to the interruption of heartbeat data.

[0041] Design of response message simulation logic: During the communication process, the power terminal will respond to requests from the communication network (such as data query, control command, etc.). The fake deception device needs to design a set of simulation logic to generate response messages that meet the requirements of the power protocol. These response messages need to simulate the normal working state of the power terminal, including the accuracy and completeness of the data and the timeliness of the response.

[0042] The developed simulation strategy needs to be implemented on the fake deception device and its effectiveness needs to be verified through actual testing. If problems or deficiencies are found in actual application, the simulation strategy needs to be adjusted and optimized accordingly to ensure that the fake deception device can work stably and long-term.

[0043] S104, the pseudo-deception device generates heartbeat data according to the simulation strategy; sends the heartbeat datagram to the power-dedicated business platform through a satellite channel to simulate the online status of the power terminal; intercepts the response message of the power-dedicated business platform to the heartbeat datagram; simulates the response message of the power terminal according to the simulation logic of the response message; sends the simulated response message to the power-dedicated business platform to maintain the communication interaction between the terminal and the power-dedicated business platform.

[0044] The fake deception device first determines the specific content that should be included in the heartbeat data packet according to the heartbeat protocol specification of the power terminal, including the terminal's unique identifier (such as MAC address, serial number, etc.), current status (such as online, standby, fault, etc.), timestamp, and other monitoring or status information that needs to be transmitted.

[0045] According to the format requirements of the heartbeat protocol, the determined data content is encoded into a binary or specific format message, which involves the filling of data fields, the calculation of checksums, etc.

[0046] Because satellite communication has the advantages of wide coverage and no geographical restrictions, it is particularly suitable for power terminals in remote areas or those that cannot directly access wired networks. Pseudo-spoofing devices use satellite channels (such as the Beidou satellite communication system or other satellite communication networks) as a medium for data transmission.

[0047] To ensure the security of data transmission, the fake deception device encrypts the heartbeat datagram and then sends it to the power-specific business platform. The encryption process uses public key encryption, symmetric encryption, or hybrid encryption, depending on the security requirements of the system.

[0048] After sending the heartbeat datagram, the fake deception device needs to monitor the response message from the power-specific business platform. It uses network packet capture, protocol analysis and other technical means. When the response message to the heartbeat datagram is identified, the fake deception device will intercept it.

[0049] The intercepted response message needs to be parsed to extract key information, such as status confirmation, request data, etc. This information is crucial for the subsequent simulation of the power terminal response message.

[0050] According to the power regulations and the communication protocol of the power-specific business platform, the fake deception device designs a set of logic for simulating response messages, including deciding which data to simulate and how to construct the response message based on the content of the intercepted response message.

[0051] According to the designed response logic, the fake deception device fills the required data into the response message and encodes it according to the protocol specification. This also involves filling in the data field, calculating the checksum, etc.

[0052] Similar to sending heartbeat datagrams, the simulated response messages also need to be encrypted to ensure the security of data transmission.

[0053] Finally, the fake deception device sends the simulated response message back to the power-dedicated business platform through the satellite channel. After receiving these simulated response messages, the power-dedicated business platform will think that it is communicating and interacting with a normal power terminal, thus maintaining the terminal's online status.

[0054] The heartbeat data and response message are shown in Table 1 and Table 2: Table 1 Heartbeat data

[0055] Table 2 Response message

[0056] S105. Based on the communication interaction, the pseudo-spoofing device forwards the business datagram between the power terminal and the power-dedicated business platform.

[0057] On the basis of the communication interaction, that is, after the simulation of the heartbeat datagram and response datagram between the power terminal and the power-dedicated service platform is realized through the power protocol pseudo-deception device, the pseudo-deception device further assumes the important responsibility of forwarding the service datagram. This step is the key link to ensure that the actual service data can be smoothly transmitted between the power terminal and the power-dedicated service platform.

[0058] Specifically, the pseudo-spoofing device not only simulates non-business datagrams (such as heartbeat datagrams and response datagrams) to maintain the stability and connection status of the communication link under the condition of limited satellite communication, but it is also responsible for forwarding actual business datagrams between the terminal side and the platform side. These business datagrams include key information such as monitoring data, control instructions, status reports, etc. of various power equipment, which are indispensable communication content in the power system.

[0059] During the forwarding process, the fake deception device will process the service datagram appropriately (such as encryption, encapsulation, etc.) according to the requirements of the power protocol to ensure the security and integrity of the data during transmission. At the same time, the fake deception device also needs to monitor the status of the communication link, and promptly detect and handle possible communication failures or data loss to ensure the reliable transmission of service datagrams.

[0060] Furthermore, in order to ensure that the pseudo-spoofing device can effectively communicate with the power-specific business platform, power protocols (such as IEC61850, IEC60870-5-104, etc.) define the communication method and data format between devices in the power system. According to the specific power protocol type, configuring the corresponding communication protocol stack is the basis for realizing the pseudo-spoofing function.

[0061] Furthermore, the heartbeat datagram and response message are important components of the communication between the power terminal and the power-dedicated service platform. According to the configured communication protocol stack, the encapsulation format of these messages is customized to match the processing mechanism of the power-dedicated service platform, thereby ensuring that the pseudo-spoofing device can successfully simulate the communication behavior of the power terminal.

[0062] Furthermore, according to the normal communication mode of the power terminal, the reasonable sending frequency of the heartbeat data is studied and determined. This frequency should match the frequency expected by the power-specific business platform to avoid abnormal detection or misjudgment of the platform.

[0063] Furthermore, in order to ensure that the fake deception device can successfully simulate the power terminal, it is necessary to design a reasonable response message simulation logic. This includes ensuring that the simulated response message is consistent with the actual response message of the power terminal in terms of content, and that the timing should also meet the expectations of the power-specific service platform to maintain the continuity and stability of communication.

[0064] Furthermore, the communication status between the pseudo-deception device and the power-dedicated business platform is monitored in real time, including but not limited to key indicators such as connection status, data transmission rate, and packet loss rate.

[0065] Furthermore, according to the monitored communication status, the simulation strategy is adjusted in time to deal with communication anomalies or network changes. For example, when it is found that the network delay increases, the sending frequency of heartbeat data or the sending timing of response messages can be appropriately adjusted to maintain the stability of communication.

[0066] Furthermore, in order to ensure the security and integrity of business data during transmission, the fake deception device should perform security verification and encryption on the business datagram. This can effectively prevent data from being tampered with or stolen during transmission and ensure the safe and stable operation of the power system.

[0067] Furthermore, before the power terminal is connected, its identity authentication and authority verification are performed through a fake deception device. This step can ensure that only legitimate power terminals with corresponding permissions can access the power-specific business platform, thereby enhancing the security and reliability of the system.

[0068] Furthermore, when multiple fake deception devices are deployed, they do not communicate directly with each other. This design is to simplify the system structure, reduce communication complexity and reduce potential security risks. At the same time, it is also convenient to independently manage and maintain each fake deception device.

Based on the communication interaction, the pseudo-deception device forwards the business datagram between the power terminal and the power-dedicated business platform.
