State Grid Heilongjiang Electric Power Research Institute Applies for Patent on "Blockchain-Based Secure Data Exchange Method and Device" to Enhance Data Security and Efficiency

On December 5, 2024, the State Intellectual Property Office of China revealed that the Electric Power Research Institute of State Grid Heilongjiang Electric Power Co., Ltd. filed a patent application for a "Blockchain-Based Secure Data Exchange Method and Device," with publication number CN119071041A and an application date of August 2024. This patent application aims to address the issues of poor security and low efficiency in existing data exchange processes, providing a novel technological solution for secure and efficient data transmission in the power industry.

The patent abstract details the technical principles of the method and device. It belongs to the field of data exchange technology and utilizes blockchain technology to construct a secure and reliable data exchange platform. The core of this method lies in the integration of enhanced data security and efficiency, effectively addressing the challenges faced by traditional data exchange methods.

Specifically, the patented method involves several key steps: First, the sending end receives the target data and publishes its descriptive information to the blockchain repository. This step ensures data traceability and transparency, laying the foundation for subsequent data security management. Second, the sending end encrypts the target data, generating ciphertext that is then stored in the blockchain repository. Encryption is crucial for data security, and storing the ciphertext leverages blockchain's immutability, further enhancing security.

Next, the receiving end needs to obtain access permission for the target data from the blockchain repository. This step controls data access rights, preventing unauthorized access and data breaches. Only authorized receiving ends can proceed. After obtaining access permission, the receiving end can access the corresponding ciphertext in the blockchain database. Finally, the receiving end decrypts the ciphertext, completing the data exchange.

The entire process fully utilizes blockchain characteristics, such as decentralization, immutability, and transparency, ensuring secure and reliable data exchange. Compared to traditional centralized data exchange methods, this method offers significant advantages:

First, significantly enhanced security. Traditional centralized methods rely on a central server for data storage and transmission; an attack or data breach on this server would cause significant losses. This method uses blockchain's decentralized nature to distribute data across multiple nodes. Even if some nodes are attacked, the system's security and data integrity remain unaffected. Furthermore, the use of encryption further enhances data security, effectively preventing unauthorized access and tampering.

Second, significantly improved efficiency. Traditional data exchange often involves multiple intermediate steps, resulting in low efficiency and delays. This method uses blockchain technology to streamline the data exchange process, reducing intermediate steps and improving efficiency. Blockchain's distributed storage and processing mechanisms effectively share processing pressure, increasing system throughput and data exchange speed.

Third, enhanced data traceability. Blockchain's immutability ensures that all operations in the data exchange process are recorded on the blockchain, and no operations can be deleted or modified. This provides complete data traceability, facilitating audits and accountability, and effectively preventing malicious tampering or forgery.

Additionally, the method offers transparency and auditability. All data exchange operations are recorded on the blockchain, allowing any party to verify and audit them, increasing transparency and trustworthiness.

In summary, the "Blockchain-Based Secure Data Exchange Method and Device" patent applied for by the State Grid Heilongjiang Electric Power Research Institute provides an innovative solution for secure and efficient data transmission in the power industry. By leveraging the advantages of blockchain technology, it effectively addresses the issues of poor security and low efficiency in existing data exchange processes, possessing significant application value and market potential. This technology will provide strong technological support for the digital transformation and intelligent upgrading of power systems, driving the power industry towards greater security, efficiency, and reliability. The successful patent application demonstrates the State Grid Heilongjiang Electric Power Research Institute's strength in technological innovation and its proactive exploration, contributing to the technological advancement of China's power industry. In the future, with the continuous development and maturation of blockchain technology, this technology is expected to find wider application in various fields, providing strong guarantees for secure and efficient data transmission across industries.
