Research on Smart Contract Uplink Method and Tamper Resistance Technology Considering Power Data Security

随着“大云物移智链”等数字化技术在能源电力领域迅猛发展,大量新兴技术快速地在电网业务系统中进行创新应用,导致用电信息采集系统中数据交互更加频繁,从而出现数据经过流转后发生缺失、损坏等问题,进而导致业务数据公信力下降,且流转过程不清晰不透明,难以进行数据追溯溯源。针对用电信息采集系统数据可信度低、溯源难等问题,分析了区块链技术在用电信息采集系统应用情况,设计了区块链-用电信息采集系统三元结构模型,提出了一种采用区块链-用电信息采集系统三元结构的基于改进模型的实用型哈希算法的结构防篡改加密算法。仿真结果表明,区块链-用电信息采集系统三元结构的防篡改加密算法可提升数据质量进而提升业务数据公信力,同时通过该结构增强了数据的溯源能力,极大提升了用电信息采集系统数据在交互和使用过程的安全性。

With the rapid development of digital technologies such as big data,cloud computing,Internet of things,mobile Internet,artificial intelligence,and blockchain in the field of energy and electricity,a large number of emerging technologies are rapidly being innovatively applied to the power grid business system.This results in more frequent interactions between the terminal and power consumption information acquisition system,leading to data loss and damage in the power consumption system after circulation,which detracts from the credibility of business data.In addition,the unclear and opaque circulation process makes it difficult to trace the source of the data.To address the problems of low credibility and difficult traceability of data in a power consumption information acquisition system,this study analyzes the application of blockchain technology in the power consumption information acquisition system,thereby designing a ternary structure model of the blockchain-power consumption information acquisition system.The study proposes a practical Hash algorithm based on an improved model using the ternary structure of the blockchain-power consumption information acquisition system for a structural tamper resistance encryption algorithm.The simulation results show that the tamper resistance encryption algorithm of the ternary structure of blockchain-power consumption information acquisition system can improve data quality and enhance the credibility of business data.This structure concurrently enhances the traceability of the data,which markedly improves the security of data exchange and use in the collection system.
