[0058] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0059] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0060] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0061] Example 1

[0062] Reference Figure 1-Figure 3 , which is the first embodiment of the present invention, provides a secure and trusted interaction method for photovoltaic data, including:

[0063] S1: Install encryption terminals, deploy edge security gateways, and establish key and database encryption systems to build a secure photovoltaic data interaction infrastructure;

[0064] S2: Implement data encryption and key management based on the photovoltaic data security interaction infrastructure;

[0065] S3: Start the trusted measurement process, the border gateway triggers the assessment, collects the integrity report of each node, and submits it to the trusted assessment submodule for verification to check the credibility of the node status;

[0066] S4: Generate a report based on the assessment results and verify the completeness.

[0067] In the embodiment of the present application, the above step S1 includes the following sub-steps A1-A3:

[0068] In A1: At the photovoltaic data access end, a plug-and-play encryption terminal is installed for the data transmission unit acquisition terminal.

[0069] In A2: Deployment of edge security gateway includes:

[0070] An edge security gateway is deployed at the front end of the trusted control system. The security gateway is used for real-time decryption. The photovoltaic data uploaded through the encryption terminal is decrypted and sent to the business system. The security gateway is also used to protect data transmission. The instructions and parameter data sent by the trusted control system to the access end are encrypted in real time before being sent.

[0071] In A3: Establishing the key and database encryption system includes:

[0072] Generate, store and manage the keys required for encryption and decryption through the key system;

[0073] The photovoltaic data in the production database is encrypted and stored through the database encryption system.

[0074] It should be noted that if Figure 2As shown in the figure, at the photovoltaic data access end, by adding a plug-and-play encryption terminal to the TTU (data transmission unit) acquisition terminal, the system can achieve reliable transmission of photovoltaic data. The plug-and-play feature of the encryption terminal makes installation and configuration very simple, and through identification, each encryption terminal forms a one-to-one intelligent binding with the corresponding TTU terminal, ensuring the reliability and accuracy of data transmission. This intelligent binding mechanism not only improves the efficiency of data transmission, but also avoids data confusion and errors.

[0075] It is of great significance to deploy an edge security gateway in the trusted control center. The security gateway is located at the front end of the trusted control system and plays the role of real-time decryption. It is responsible for decrypting the photovoltaic data uploaded by the encryption terminal in real-time encryption and sending it to the business system. At the same time, the edge security gateway also acts as a guardian of data transmission, responsible for encrypting the instructions, parameters and other data sent by the trusted control system to the access end in real time before sending them. This dual protection mechanism of real-time decryption and encryption ensures the confidentiality and integrity of data during transmission, effectively resists potential security threats, and ensures the safe transmission of photovoltaic data.

[0076] In the operation and maintenance center, the deployment of the key system and database encryption system provides a basic guarantee for the long-term security of photovoltaic data. The role of the key system is to generate, store and manage the keys required for encryption and decryption. Through reasonable key management, key leakage and abuse can be effectively avoided, ensuring the security of data transmission and storage. The database encryption system is responsible for encrypting and storing photovoltaic data in the production database. Even if the encrypted data is illegally obtained under unexpected circumstances, it is difficult to interpret due to the protection of the encryption algorithm, which protects the privacy and confidentiality of photovoltaic data. Such measures not only meet regulatory compliance requirements, but also provide a solid guarantee for the long-term stable operation of photovoltaic power generation systems.

[0077] The encryption terminal at the photovoltaic data access end, the edge security gateway of the trusted control center, and the key system and database encryption system of the operation and maintenance center each play a key role and jointly build a safe and reliable photovoltaic data transmission and storage system.

[0078] In the embodiment of the present application, the implementation of data encryption and key management based on the photovoltaic data security interaction infrastructure in the above step S2 includes the following sub-steps B1-B2:

[0079] B1: Based on the TTU terminal for PV data collection and the PV database for collecting data, the PV data is encrypted using an encryption algorithm;

[0080] B2: The keys generated during the encryption process are distributed to the TTU encryption terminal and the security gateway connected to the front end of the trusted security management center.

[0081] Specifically, the RSA encryption algorithm is used to encrypt the photovoltaic data in the TTU terminal for photovoltaic data collection and the photovoltaic database for collecting data.

[0082] like Figure 3 As shown, the specific process of RSA is:

[0083] First, a random number generator generates two large prime numbers p and q. Then the product N of the two prime numbers is calculated: N = p × q. N is part of the public key and private key.

[0084] Find the value of the Euler function Φ, where Φ(n) represents the Euler function of the variable n and represents the number of positive integers in the range [1, n-1] that are coprime with n.

[0085] Φ=(p-1)×(q-1) (1)

[0086] Find the public key (E, N), where E is a positive integer between (1, Φ(n)), E and Φ(n) are relatively prime, ensuring that the public key and private key correspond one-to-one.

[0087] Find the private key (D, N), D is determined as follows:

[0088] 1<D<Φ(n), D×EmodΦ(n)=1 (2)

[0089] It should be noted that through RSA encryption, the trusted security management module can use the public key of the photovoltaic data acquisition module to encrypt the session key and then send it to the data acquisition module. This ensures the secure transmission of the session key, even in a public network, where only the data acquisition module with the private key can decrypt and use the key. After the data transmission is completed, the data acquisition module can use its private key to digitally sign the data and attach the digital signature to the data. The receiver can use the public key of the data acquisition module to verify the authenticity and integrity of the digital signature. In this way, the receiver can ensure that the received data is generated by a legitimate data acquisition module and has not been tampered with during the transmission process.

[0090] The generated keys are respectively issued to the TTU encryption terminal and the security gateway connected to the front end of the trusted security management center: To ensure the security of the key transmission process, the trusted security management center issues the session key K, which is used to encrypt the public key (E, N) and private key (D, N) generated by the photovoltaic data encryption. The session key K is only issued to the TTU encryption terminal and the security gateway connected to the front end of the trusted security management center. The key is securely transmitted, the data integrity is verified and digitally signed, thus providing the security and credibility of data transmission and storage. Both parties in the photovoltaic data transmission must first generate the public key (E, N) and private key (D, N) through the session key K, and then verify it to ensure the security of photovoltaic data transmission in the system.

[0091] In the embodiment of the present application, in the above step S3, based on the photovoltaic data security interaction infrastructure, data encryption and key management are implemented to collect the integrity report of each node, and submitted to the trusted evaluation submodule for verification. Checking the credibility of the node status includes the following substeps C1-C6:

[0092] C1: The trusted access controller of the border gateway sends an assessment activation message to the assessment management submodule of the security gateway.

[0093] C2: The border gateway assessment management submodule sends the activation message to the assessment management submodule of the external data collection node;

[0094] C3: The external collection node assessment management submodule sends an integrity request message to the integrity measurement submodule of the integrity measurement layer;

[0095] C4: The external node integrity measurement submodule generates an integrity report message based on the integrity request message and sends it to the trusted reporting submodule of the trusted request visitor;

[0096] C5: The external node trusted report submodule generates a trusted report and sends it to the trusted report submodule of the border gateway.

[0097] C6: The border gateway trusted reporting submodule sends an integrity request message to the node integrity measurement submodule of the integrity collector.

[0098] In the embodiment of the present application, generating a report based on the evaluation results and verifying the integrity in the above step S4 includes the following sub-steps D1-D8:

[0099] D1: The border gateway integrity measurement submodule generates an integrity report message based on the integrity request message and sends it to the trusted report submodule.

[0100] D2: The trusted report submodule generates a trusted report and sends it to the trusted assessment submodule of the trusted security management center assessment policy server instance.

[0101] D3: The trusted assessment submodule extracts the integrity report message from the trusted report and sends it to the integrity verification submodule of the integrity verifier of the security management center.

[0102] D4: The integrity verification submodule compares the integrity report with the trusted reference library, obtains the integrity verification result and sends it to the trusted assessment submodule.

[0103] D5: The trusted assessment submodule sends the assessment verification results to the assessment report submodule.

[0104] D6: The evaluation report submodule signs the evaluation verification result and sends the signed evaluation report to the certificate authentication request submodule of the border gateway.

[0105] D7: The border gateway trusted verification submodule verifies the integrity of the node evaluation report. After confirmation, the node evaluation report is sent to the evaluation management submodule. At the same time, the part of the evaluation report that evaluates the credibility of the border gateway is sent to the external node that initiates the trusted connection.

[0106] D8: After the external node trusted verification submodule confirms the credibility of the assessment report, it forwards the assessment result to the assessment management submodule.

[0107] It should be noted that after the trust evaluation process, both the external node and the border gateway can receive the trust evaluation results of the other party given by the security management center. This result is based on the trust chain of the system and has a high degree of credibility.
