摘要
传统电力数据传输和存储系统存在数据可信性和安全性差等问题,而区块链技术的去中心化和防篡改等特性能够有效解决恶意篡改、单点故障等问题,然而电力数据数量庞大、来源广泛、节点类型复杂,目前仍缺乏高效可靠的数据上链方式。为此提出一种基于区块链和预言机技术的链上链下电力数据协同控制方案,通过优化数据上链方式,建立分布式预言机可信上链机制,解决海量数据上链的可信性难题。安全性分析和实验测试证明了该方案的安全性、高效性与可靠性。
The traditional power data transmission and storage system has the problems of poor data credibility and security,and the decentralization and tamper-proof characteristics of blockchain technology can effectively solve the problems of malicious tampering and single point of failure.However,there is a huge amount of power data,a wide range of sources,and complex node types,and there is still a lack of efficient and reliable data chain way.Therefore,a collaborative control scheme for on-chain and off-chain power data based on blockchain and oracle technology is proposed.By optimizing the data on-chain mode,a distributed oracle trusted on-chain mechanism was established to solve the credibility problem of massive data on-chain.Security analysis and experimental tests prove the security,efficiency and reliability of the proposed scheme.
