摘　　要：为解决高速铁路分布存储的监测数据遭受数据恶意篡改、共享困难等问题,提出基于联盟链的去中心化的双链存储模型。采用无线传感器网络和区块链技术构造高速铁路联盟链感知节点分布框架和数据存储联盟链模型,通过数据采集基站共识形成数据区块链。基于数据的属性、哈希值等信息形成具体类型的hash链,便于对同一类监测项目的历史数据进行分析、总结。安全性能分析表明,数据联盟存储链能实现安全、可靠的存储铁路沿线监测数据。To solve the problem that the monitoring data of high-speed railway distributed storage suffer from maliciously data tampering and sharing difficulties,a decentralized double-chain storage model based on consortium chain was proposed.The wireless sensor network and blockchain technology were used to construct the high-speed railway consortium chain sensing node distribution framework and data storage consortium chain model.The data blockchain was formed by data acquisition base station consensus.Based on data attributes,hash values,and other information,a specific type of hash chain was formed,which facilitated analysis and summary of historical data of the same type of monitoring items.Security performance analysis shows that the data consortium storage chain can store monitoring data along the railway safely and reliably.
