Description

Technical Field

[0001] The present invention relates to the field of green electricity source tracing, and specifically provides a green electricity source tracing method. Background Art

[0002] Faced with the international situation of global warming and carbon emission reduction, my country has proposed the dual carbon goals of achieving carbon peak by 2030 and carbon neutrality by 2060. According to the latest data, China's emissions accounted for 27% of the world's total emissions in 2019, with carbon emissions reaching 14.093 billion metric tons of carbon equivalent, far exceeding the second-ranked United States (11% of emissions), which shows that the situation of energy conservation and carbon reduction is very severe. At present, the calculable and measurable forms of energy circulation and trading are mainly electric energy. However, which electric energy is generated by renewable energy (this part of electric energy is usually called green electricity) and how this part of green electricity is used and traded have received widespread attention from design countries.

[0003] my country has established a third-party agency to ensure that green electricity data is authentic, objective and fair through green electricity verification. However, green electricity traceability has the characteristics of a long chain and many links, and cross-power data collaboration is complex. How green electricity data can be accepted by third-party agencies has become a problem.

[0004] The current methods of tracing the source of green electricity are: first, by installing collection equipment to collect power generation data and storing it on the blockchain. This method has problems such as the identity of the collection equipment not being recognized and data falsification due to network security, illegal access, etc.; the second method is to trace the source of electricity by storing the power purchase transaction data on the blockchain, but whether the electricity is truly derived from renewable energy needs to be discussed. Summary of the invention

[0005] The present invention aims at solving the above-mentioned deficiencies of the prior art and provides a green electricity source tracing method with strong practicality.

[0006] The technical solution adopted by the present invention to solve the technical problem is:

[0007] A green electricity traceability method that actively allocates identification, applies for identification, writes identification, performs equipment identification security authentication and key security technology on green electricity equipment, realizes digital identity authentication and management of Internet of Things equipment through the SM9 national secret algorithm, and stores power generation information, transaction information, transmission information and electricity consumption information on blockchain through open interfaces to form a green electricity traceability data chain.

[0008] Furthermore, the identification application is applied for manually and robotically;

[0009] The manual method is that the administrator logs in to the enterprise SM9 key center system to apply for an identification key, and then copies the identification key to the device;

[0010] The robot method is that the robot or one-end program applies for an identification key by calling the SM9 key center API through the SDK, and then writes the identification key to the location specified by the device.

[0011] Furthermore, key management is performed in the digital identity authentication and management of IoT devices. The key management includes the generation and security protection of master public keys and master private keys, the addition, deactivation and activation of identification administrators, the access control of the SM9 key center, the generation and issuance of identification keys, and the saving of identifications to the blockchain SM9 identification library.

[0012] Furthermore, a blockchain device identification library is implemented in the digital identity authentication and management of IoT devices. The blockchain device identification library performs global device identification storage to ensure the global uniqueness of the identification, the connection between the SM9 key centers of each enterprise, and the exchange, dissemination and synchronization of device identification. The blockchain smart contract technology is used to verify the legitimacy of the identification, ensure that the device identification is globally unique, and save the global device identification.

[0013] Furthermore, after the master private key is generated in the digital identity authentication and management of IoT devices, it is sharded and handed over to multiple entities for management. Multi-party secure computing is used during calculation to generate a private key corresponding to the identification.

[0014] Furthermore, trusted computing is performed in the digital identity authentication and management of IoT devices, and a signature key is injected into the IoT device. It is randomly generated when the device chip leaves the factory and cannot be changed. This private key is always in the chip, and the public key is used to authenticate and encrypt sensitive data sent to the chip.

[0015] Furthermore, after the master private key is generated, it is divided into pieces and handed over to multiple entities for management. During calculation, each piece is loaded into a trusted hardware environment, and then a private key corresponding to the identifier is generated.

[0016] Furthermore, in the green electricity traceability and evidence service, the platform layer, data layer, service layer and display layer,

[0017] The platform layer stores power generation information, transaction information, transmission information and power consumption information on the blockchain, mainly providing interface calls and data on-chain storage, and supports verification of green power storage information;

[0018] The data layer performs data modeling, data cleaning and data asset aggregation, and delivers standard data to the service layer;

[0019] The service layer performs data uploading, data statistics, data analysis, data development and data interface;

[0020] The display layer displays information on the entire process of green electricity generation, transmission and transaction settlement.

[0021] Compared with the prior art, the green electricity source tracing method of the present invention has the following outstanding beneficial effects:

[0022] The present invention is based on active identification and blockchain technology. First, through active identification carriers and encryption algorithms, the digital identity of green power generator equipment is identified, authenticated and securely accessed. Green electricity generated by renewable energy is collected and recorded from the source, and data such as green electricity generation, transaction, transmission and use are stored through blockchain to ensure data security and reliability, providing support for third-party verification agencies. Enterprise entities can authenticate and trade green electricity generated internally, thereby improving the traceability and circulation efficiency of green electricity.

[0026] A best embodiment is given below:

[0027] like Figure 1 As shown, a green electricity traceability method in this embodiment performs active identification allocation, identification application, identification writing, device identification security authentication and key security technology on green electricity equipment, realizes digital identity authentication and management of IoT devices through the SM9 national secret algorithm, and stores power generation information, transaction information, transmission information and electricity consumption information on blockchain through an open interface to form a green electricity traceability data chain.

[0028] When applying for a logo, use manual and robotic methods:

[0029] The manual method is for the administrator to log in to the enterprise SM9 key center system to apply for the identification key, and then copy the identification key to the device;
