Research And Implementation Of Industrial Internet Data Access Control Mechanism Based On Blockchain

Industrial Internet is the deep integration and innovative application of new generation information and communication technologies in the industry,such as new networks,artificial intelligence,and big data.In the Industrial Internet,data is the core carrier of various types of information in the industrial field.Through data sharing,the interconnection and intercommunication of various information resources in the Industrial Internet supply chain can be realized,and then intelligent management and control decisions can be made,and efficient collaboration between enterprises can be realized.However,industrial data is usually confidential,and data sharing requires controlled access to the content.To this end,this paper starts from the data sharing scenario in the Industrial Internet supply chain and designs a blockchain-based Industrial Internet data access control framework to ensure the controlled sharing of data between enterprises in each link of the supply chain.Industrial data is usually stored locally in the enterprise to ensure security.At this time,data sharing requires the use of a centralized third-party platform to complete access control decisions.However,third-party platforms still have the risk of being attacked,leading to erroneous access control results and threatening data security.In addition,Industrial Internet applications such as supply chains are usually executed in the form of workflows,and their data access tasks are dependent on each other.However,there are relatively few studies on access control mechanisms for complex processes at this stage,and there is a lack of suitable Industrial Internet access control application in the supply chain environment.To this end,this article aims at the access control requirements of data sharing in the Industrial Internet supply chain scenario,using blockchain to provide trusted storage,smart contracts to provide trusted computing,and workflow models to provide multi-party collaboration capabilities,realizing blockchain-based Industry Internet data access control prototype system.Mainly include the following aspects:(1)Aiming at the problem of distributed access control in data sharing between enterprises,this paper designs a blockchain-based Industrial Internet data access control mechanism.The blockchain platform is used to provide credible storage for information such as access control attributes and policies,and smart contract technology is used to ensure credible calculation of access control decisions.(2)Aiming at the problem of complex process access control in supply chain data sharing,this paper designs an access control mechanism for Industrial Internet workflow.Use workflow to model the data sharing process between multiple parties,and use workflow task status information to assist access control decisions at this time.(3)Designed and implemented a blockchain-based Industrial Internet data access control prototype system,and implemented two modules.The data management module manages Industrial Internet data in the form of a data unified interface,and the blockchain module is implemented based on Hyperledger fabric framework,which is responsible for providing access control services during data sharing.In summary,this paper has conducted an in-depth exploration of the access control mechanism to ensure controlled sharing of data in the Industrial Internet supply chain scenario,and on this basis,has designed and implemented a blockchain-based Industrial Internet data access control prototype system.This research will help build a data-sharing system for the Industrial Internet supply chain,which can be further applied to other areas of the Industrial Internet.
