A Patent Granted for a Secure Communication Method and System for Train Control Systems Based on Resource Virtualized Blockchain

On March 29, 2025, the State Intellectual Property Office of China announced that Tonghao Urban Rail Transit Technology Co., Ltd. successfully obtained a patent for a "Secure Communication Method and System for Train Control Systems Based on Resource Virtualized Blockchain," with publication number CN119696819A and an application date of November 2024. This achievement marks a significant breakthrough in China's train control system security communication technology, providing strong technical support for enhancing the safety and reliability of train control systems.

The patent abstract details the core technology: a secure communication method and system for train control systems based on resource virtualized blockchain. This method cleverly leverages blockchain and resource virtualization technologies to effectively address the communication security challenges of traditional train control systems, laying a solid foundation for building safer and more reliable rail transit systems.

Specifically, the patented method involves several key steps: First, upon receiving a communication instruction from the train control communication system, the system automatically identifies the corresponding sending and receiving subsystems. Importantly, the train control communication system itself comprises sending and receiving subsystems, reflecting a modular system design that simplifies management and maintenance.

Next, the system calls the sending blockchain node corresponding to the sending subsystem to authenticate the received communication instruction. This step ensures the reliability of the instruction's origin, effectively preventing malicious intrusions. Only authenticated instructions proceed, guaranteeing the safe operation of the train control system.

After authentication, the system uses the sending blockchain node to transmit the communication content to the receiving blockchain node corresponding to the receiving subsystem. This process utilizes the decentralized nature of blockchain technology, mitigating single points of failure and enhancing the system's fault tolerance and reliability.

The receiving blockchain node then further authenticates the received content, ensuring its integrity and authenticity. This complements the previous instruction authentication, jointly safeguarding communication security.

Finally, after content authentication, the receiving blockchain node forwards the content to the receiving subsystem, completing the communication process. The entire process prioritizes security, reliability, and efficiency, highlighting the advanced and practical nature of this patented technology.

Through this method, Tonghao Urban Rail Transit Technology Co., Ltd. has achieved a decentralized secure communication approach for train control systems. This not only improves security but also points towards the intelligent development of future rail transit systems.

Importantly, this technology significantly enhances the train control system's anti-interference capabilities and security, effectively reducing the risk of train accidents due to communication failures, thereby substantially improving the overall safety of rail transit systems. This is crucial for protecting passenger lives and property and promoting the healthy development of the rail transit industry.
