Design Of Energy Internet Security Transaction Platform Based On Blockchain

Blockchain has developed rapidly in recent years and helps provide some Internet applications in distributed scenarios.The characteristics of its decentralization and peerto-peer transactions have set off a revolutionary research and application boom in the field of digital currency.At present,the application of blockchain is gradually moving from the financial field to various fields.In the energy field,the concept of the energy Internet has received widespread attention which aims to reform open,collaborative and intelligent energy market.The technology of consortium blockchain is suitable to build distributed energy transaction.It is necessary to construct the application model of blockchain in the scenario of energy Internet.This paper analyzes the characteristics of the energy Internet scenario and blockchain technologies such as P2 P network and smart contracts.Based on the Hyperledger Fabric open source project of the consortium chain,this paper designs a set of blockchain secure transaction platform in the scenario of energy internet.An extended access control model for energy Internet scenarios is proposed to meet its security requirements.The research work are as the follows:Firstly,this paper analyzes the combination of energy Internet and blockchain technology,and introduces the underlying technology of blockchain application and consortium chain development platform Hyperledger Fabric.The basic framework of the blockchain energy trading platform is built based on the six-layer model architecture of the blockchain trading platform with the actual application scenarios of the energy Internet.Secondly,based on the analysis of the security requirements of the energy Internet scenario and the Hyperledger Fabric access control mechanism,the extended access control model EB-BAC under the Energy Internet scenario is designed according to the characteristics of the RBAC and ABAC models.A formal description of the main elements in the model is given,and access control rules for user-role and role-permission allocation based on attribute expressions and model constraints are defined.The specific model application analysis through the power market transaction scenario is listed,which proves its rationality and feasibility to deal with the dynamic access control problem in the distributed network scenario.Thirdly,based on the Hyperledger Fabric platform simulation,a blockchain network under the energy Internet scenario is achieved.The functional interaction of the blockchain secure transaction platform is implemented through commands.The chaincode is deployed to the network for invocation,and the automatic execution of energy transactions and deposit in the distributed ledger are realized.For the application process of the EB-BAC model in this specific scenario,the channel configuration service and chaincode design are used to implement the platform's secure access control function.In this paper,a secure blockchain platform and access control model are designed to ensure open and intelligent energy transaction,which applies the consortium chain and access control technology.The set of this platform provides a new application method for blockchain energy trading scenarios.
