计及电力数据安全的智能合约上链方法及防篡改技术研究OA北大核心CSTPCD

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.
