LuNeng Power Generation Company in Huainan, Anhui Province, Applies for Patent on "Trustworthy Data Synchronization Method and System Between DCS Terminals" to Enhance Data Security

On December 23, 2024, the State Intellectual Property Office of China announced that Anhui Huainan LuNeng Power Generation Co., Ltd. had applied for a patent titled "A Trustworthy Data Synchronization Method and System Between DCS Terminals," with publication number CN119155305A and an application date of July 2024. This invention aims to address security and reliability issues in data synchronization between Distributed Control System (DCS) terminals. By incorporating blockchain technology and multiple verification mechanisms, it ensures data integrity and trustworthiness, effectively improving the data security level of industrial control systems.

The patent abstract details the method and system workflow. First, the server receives data synchronization requests from DCS terminals. Before processing, the server conducts rigorous security checks and data preprocessing. This includes analyzing historical behavior data and device fingerprints to generate dual anomaly detection results, effectively identifying and filtering malicious requests or abnormal data. The server judges the rationality of timestamp data based on the analysis results, ensuring data authenticity and timeliness.

If the timestamp data is deemed reasonable, the server obtains a public key from the blockchain network to encrypt the data. This step is crucial, providing strong security for data transmission. The encryption process generates a primary verification information and multiple secondary verification information, used in subsequent verification and validation stages.

To further enhance data security, the patent proposes a data processing method based on sensitivity analysis. The server performs sensitivity analysis on received data, classifying it into sensitive and non-sensitive subsets. To prevent leakage and malicious use of sensitive data, the system applies perturbation processing, generating a disordered sensitive data subset before encryption. This approach effectively protects sensitive information without affecting overall data usability.

The perturbed and encrypted sensitive data subset, along with the encrypted non-sensitive data subset, constitutes the data synchronization message. This message is securely sent to the target DCS terminal. Upon receiving the message, the target terminal decrypts it, obtaining the primary verification information and multiple secondary verification information. The system then verifies data integrity and authenticity. Duplicate data is detected and removed, and the decrypted results are shared to obtain the data to be synchronized.

After successfully obtaining the data, the system performs data synchronization and uploads the synchronization results and completion certificate to the blockchain network. This ensures traceability and tamper-proof data synchronization. Finally, the system analyzes the entire process, generating a detailed synchronization report sent to the initiating terminal for monitoring and management.

The innovation lies in the ingenious combination of blockchain technology, multiple verification mechanisms, and sensitive data processing techniques. Blockchain ensures data transmission trustworthiness and tamper-proof characteristics. Multiple verification mechanisms prevent data tampering or forgery, while sensitive data processing enhances security and protects privacy.

By integrating these techniques, the proposed trustworthy data synchronization method and system effectively addresses security and reliability issues in DCS data synchronization, significantly improving efficiency and security. This is crucial for industrial control systems relying on real-time data transmission, providing strong technical support for industrial automation and digital transformation.

This patent technology has broad application prospects in various industrial sectors, including power, petrochemicals, and metallurgy, helping companies build more secure and reliable industrial control systems. Especially in the context of increasingly severe cybersecurity threats, this technology provides crucial support for the safe and stable operation of critical infrastructure. LuNeng Power Generation Company's innovation in this field deserves industry attention and study. With technological maturity and expanding applications, this patent technology will contribute significantly to the secure development of the Industrial Internet. We expect its application in more fields, contributing to a more secure and reliable digital society. We also anticipate more similar innovative technologies to further improve China's industrial control system security. This is not only related to corporate economic benefits but also to national security and social stability. Strengthening the research and application of industrial control system security protection technology is of significant strategic importance. With government support and corporate innovation, China's industrial control system security technology level will continuously improve, providing a stronger foundation for economic and social development. The patent applied for by Anhui Huainan LuNeng Power Generation Co., Ltd. vividly reflects this trend.
