摘要:
现有环境监测系统的管理大多是集中式服务,对监测数据的获取过于依赖单一的环境监测机构和第三方运营机构。 监控数据采用集中式存储管理,存在数据被有意篡改的可能性,不能保证环境数据的真实性。 首先,针对这些问题,该文利用区块链技术的去中心化、不可篡改等特性,提出一种基于区块链的环境监测的可信管理方案,通过去中心化的验证方式设立真实性验证机制保证数据源的真实可信,实现环境数据的可信验证、可信存储、可信访问。 其次,针对环境监测应用场景下实用拜占庭容错共识算法通信开销过大的问题,提出一种基于位置分组的实用拜占庭容错共识算法,降低通信开销和时延,提高系统的执行效率。 最终,基于以太坊平台并利用智能合约技术对设计的方案进行了仿真实现和测试,结果表明,基于区块链的环境监测实现了环境数据的可信管理。
Abstract:
The management of existing environmental monitoring systems is mostly centralized services,and the acquisition of monitoringdata is too dependent on a single environmental monitoring agency and a third-party operating agency. Monitoring data is centrally storedand managed,and may be tampered with intentionally. Therefore,the authenticity of environmental data cannot be guaranteed. Aiming atthese problems,according to the decentralization and non - tampering characteristics of blockchain technology, a trusted managementscheme for environmental monitoring based on blockchain is proposed,and an authenticity verification mechanism is established through adecentralized verification method to ensure the authenticity and credibility of data sources, and realize the trusted verification, trustedstorage and trusted access of environmental data. Then aiming at the problem that the communication overhead of the practical Byzantinefault-tolerant consensus algorithm is too large in the application scenario of environmental monitoring,a practical Byzantine fault-tolerantconsensus algorithm based on location grouping is proposed to reduce the communication overhead and delay and improve the executionefficiency of the system. Finally,based on the Ethereum platform and smart contract technology,the designed scheme is simulated andtested. The results show that the environmental monitoring based on blockchain realizes the trusted management of environmental data.
