A Secure Storage System for High-Speed Railway Monitoring Data Based on Blockchain Technology
Lifeng Ni, Rui Zhang · 2023
To address the issues of malicious data tampering and sharing difficulties in the distributed storage of high-speed railway monitoring data, this study proposes a decentralized dual chain storage model based on alliance chain. Using wireless sensor networks and blockchain technology to construct a high-speed railway alliance chain perception node distribution framework and a data storage alliance chain model, a data blockchain is formed through data collection base station consensus. Based on the attributes, hash values, and other information of the data, a specific type of hash chain is formed to facilitate the analysis and summary of historical data of the same type of monitoring project. Security performance analysis shows that the data alliance storage chain can achieve safe and reliable storage of monitoring data along the railway.
