Guangxi Power Grid Applies for Patent on Blockchain-Based Secure and Auditable Data Sharing for Smart Grids

Financial World, November 14, 2024 - According to the National Intellectual Property Administration (NIPA), Guangxi Power Grid Co., Ltd. has filed a patent for a "Blockchain-based Secure and Auditable Data Sharing Method and System for Smart Grids", with the publication number CN118940283A and the application date of March 2024.

This patent falls under the field of blockchain data sharing technology, aiming to address the issues of security and auditability in existing smart grid data sharing practices. The patent abstract indicates that the method and system achieve secure and auditable data sharing through the following steps:

System Initialization Stage:

1. Users initiate registration with the authority, obtaining identity identification.

2. Data owners encrypt power data and compute audit parameters.

3. Data owners upload the encrypted power data and audit parameters to the data storage center and record them on the blockchain.

4. Data owners generate authorization parameters and send them to the power data proxy.

Data Access Stage:

1. The data storage center calculates audit proofs based on the power data request.

2. The data proxy user re-encrypts the power data to obtain re-encrypted ciphertext tuples.

3. The data proxy user returns the re-encrypted ciphertext tuples and audit proofs to the data user.

Data Verification Stage:

1. The data user verifies the legitimacy of the audit proofs.

2. Upon verification, the data user decrypts the power data ciphertext to obtain the actual power data.

This patented method not only supports auditing the integrity of power data but also ensures data owner anonymity through proxy re-encryption technology. This means that data owners can safely share power data without worrying about data leaks or identity exposure.

Advantages of the Patent Technology:

• Secure and Auditable: Blockchain technology ensures data integrity and immutability, providing auditability and guaranteeing reliable data sources.

• Data Anonymity: Proxy re-encryption technology protects the privacy of data owners, enabling anonymous data sharing.

• Improved Efficiency: The intelligent data sharing mechanism simplifies data access procedures, improving data sharing efficiency.

Application Scenarios:

This patent technology can be applied to the secure sharing of smart grid data, such as:

• Power companies share power data with third-party data analysis institutions for analysis.

• Power companies share power consumption data with users, enhancing user power consumption experience.

• Power companies share power data with government agencies to support grid safety supervision.

Conclusion:

Guangxi Power Grid's patent application for blockchain-based secure and auditable data sharing for smart grids provides a novel solution to address the security and auditability challenges in data sharing for the smart grid, possessing significant application value and market potential. The application of this technology will promote the healthy development of smart grids and drive the digital transformation of the power industry.
