Embodiment two,

As shown in Figures 1 and 2, for the interface tool schematic diagram and flow chart thereof provided by the present invention, each step in Figure 3 is carried out in real time according to the flow chart of 2 by the interface tool of figure, specifically comprises the following steps:

1) The electricity sales system first generates a quotation file. Specifically: at the end of the electricity sales system, the quotation information is generated into a text file. The format of the file includes but is not limited to XML, JSON, CIM/E, etc. The content of the file includes the transaction sequence ID, market member ID, time, segment number, and electricity price , electricity, electricity, etc. Among them, electricity price, electricity quantity, electric power and other sensitive data fields related to enterprise secrets are encrypted with symmetric key or asymmetric key according to the method agreed in advance between the electricity sales system and the transaction system. Sensitive data encryption:

1. The trading system and the electricity sales system agree in advance on the "sensitive data encryption key", and the keys of different electricity sales systems are different;

2. The electricity sales system will generate a quotation file for the data that needs to be quoted, and use the "sensitive data encryption key" to encrypt the sensitive data fields.

3. After the transaction system receives the quotation file, it analyzes it, keeps the encrypted state of sensitive data, and stores it in the database.

4. When it is necessary to clear the quotation, the encrypted data is taken out and decrypted to participate in the clearing sort.

Advantages: 1. Encrypt sensitive fields only, instead of encrypting the entire quotation file: under the premise of ensuring security, the processing speed of encryption and decryption is improved. 2. Keep the data encrypted when storing in the database to avoid the leakage of commercial secrets caused by database security issues.

2) Save quotation information such as transaction sequence ID, market member ID, time, segment number, electricity price, electricity, electricity, etc. in a text file, which can realize cross-platform transmission and is convenient for manual reading and modification. The quotation file can be manually generated and transmitted to the trading system to reduce the risk of being unable to participate in power trading caused by the downtime of the electricity sales system.

The generated quotation file can be in various file formats such as XML, JSON, CIM/E, etc., which is convenient for data interaction between heterogeneous systems of different developers.

Separately encrypt the sensitive data fields in the quotation file, such as electricity price, electricity, electricity and other information, to avoid the risk of corporate secret leakage during the transmission process.

The following is an example of a quotation file for "Monthly Bidding Electricity Segmentation Declaration" in CIM/E format.

The following is an example of a quotation file for "declaration of 96-point daily electricity consumption curve" in JSON format.

The following is an example of an offer file in XML format with encrypted and signed offer content.

2) Transfer the quotation file through the transmission channel. Support the transmission of quotation files from the electricity sales system to the electricity trading system. During the transmission process, use user name/password, SSH, digital certificate, SSL/TLS and other technologies for identity authentication, transmission encryption, etc., to ensure the confidentiality and integrity of quotation files sex and non-repudiation. Transmission channel: Both automatic interaction and manual interaction are provided, and the last file transmission time is taken as the quotation time. in:

1. The automatic interaction mode of the transmission channel provides an API interface in the form of WebService or WebSocket, which is automatically called and transmitted by the electricity sales system program.

2. Provide SFTP service in manual interactive mode, you can manually log in to the SFTP service, and upload the quotation file to the specified directory to complete the quotation.

3. When a certain electricity sales system transmits the quotation file through multiple methods, the time of the quotation file received latest is taken as the final quotation time.

Advantages: 1. The automatic interactive method can satisfy the rapid declaration of large quantities of data. An important sorting parameter for power trading quotations is the quotation time. Since it is automatically interacted through the API, the quotation can be completed earlier, so as to obtain a higher ranking and increase the probability of winning the bid. 2. The manual interaction method can meet the requirements of manual submission of quotation documents in the case of a failure of the electricity sales system, so as to avoid the failure to participate in the quotation due to external uncontrollable reasons, which will cause economic losses to the electricity sales company.

Identity authentication adopts digital certificate two-way identity authentication method, including:

①The electricity sales system sends a connection request to the trading system.

②The trading system sends its own certificate and information related to the certificate to the electricity sales system.

③The electricity sales system checks whether the certificate sent by the server is issued by a trusted CA center. If yes, continue to execute the protocol; if not, terminate the connection and return identity authentication failure information.

④ Then the electricity sales system compares the information in the certificate, such as the domain name and public key, with the relevant information just sent by the trading system. If they are consistent, the electricity sales system recognizes the legal identity of the trading system.

⑤The trading system requires the electricity sales system to send the certificate of the electricity sales system. After receiving it, the trading system verifies the certificate of the electricity selling system, and if it fails the verification, it refuses to connect; if it passes the verification, the trading system recognizes the legal identity of the electricity selling system and obtains the public key of the electricity selling system.

⑥ As a result, the electricity sales system and the trading system complete the identity verification process and obtain the public key of the other party, which can be used for subsequent encrypted communication.

When using FTP, you should use a secure transmission protocol such as SFTP or FTP over SSL (hereinafter referred to as FTP). The trading system runs the FTP server program to set up a user name and password (or digital certificate) for all electricity sales systems, and prepares to upload the interface; Securely connect and then transfer the compliant offer file to the specified interface within the specified time.

When using WebService or WebSocket, secure transmission methods such as SSL/TLS should be used. The transaction center provides the WebService or WebSocket interface, specifies the interactive API, and sets up AppKey and AppSecret (or digital certificate) for all electricity sales systems as identity authentication measures; the electricity sales system uses the HTTP protocol to connect to the corresponding API interface, and at the specified time Upload the quotation file that meets the requirements.

3) The trading system parses the quotation file. On the power trading system side, it supports automatic reading of quotation files through the transmission interface, decrypts and parses sensitive fields into recognizable formats, judges the compliance of specified quotation information data fields, and finally enters the quotation database.

On the power trading system side, after receiving the quotation file transmitted by the power sales system, data verification is first performed, including verifying digital signatures and hash values, to ensure that the transmission process is not forged and tampered, and for electricity, electricity price, electricity, Data fields such as quotation time and segment number are used for compliance verification. Next, the quotation file is parsed, and the sensitive data field is decrypted through the pre-agreed key to confirm that the quotation information complies with the regulations of the transaction announcement. Finally, the quotation data is entered into the quotation database of the trading system, which can meet the needs of automatic large-scale bidding information submission. This completes the entire quotation data interaction process.
