Application Research Of Blockchain In Energy Internet Security Mechanism

As the representative technology of the third industrial revolution,energy Internet has changed the way of life and economic development mode of modern society.The decentralization,transparency,fairness and openness of Blockchain technology are consistent with the concept of distributed energy in the energy Internet,and its application in the energy Internet will further promote the construction of the energy Internet.Combined with the special relevance of data information in the energy Internet,this paper proposes a safe operation mechanism of energy Blockchain for the energy Internet system.The nodes in the energy Blockchain are divided into roles and controlled by permissions according to their roles,and the data nodes of different roles are supplemented with data detection algorithms to ensure that the reading and writing process of data cannot be tampered with.According to the structure division of energy Blockchain,this paper mainly does the following aspects of work:1)At the perceived execution layer,asymmetric encryption is adopted.Each sensor has its own fixed private key,and when broadcasting data to the whole network every time,a digital signature encrypted with private key is added at the end of the packet.In the network,only the authorized node can obtain the public key of other nodes and sensors.2)At the data transmission layer,the advantages and disadvantages are compared contains of workload proof POW mechanism,equity proof POS mechanism and equity proof DPOS mechanism in the energy information Blockchain.Appropriate DOPS consensus mechanism is selected based on the characteristics of the energy Internet,and the consensus mechanism is improved based on the role of nodes.3)At the contract layer,it is necessary to formulate intelligent contracts to analyze and process sensor node data to minimize the impact of bad data on data information security and grid stability in the energy Blockchain.4)At the application control layer,some extension Suggestions are proposed for data sharing of nodes.Based on the numerical example of the simulation model,the experimental results show that the proposed energy block chain security mechanism operation scheme is a scheme that can provide effective data protection and storage.
