Research of Cross-Domain Access Control of Grid Enterprise Data Based on Blockchain Technology
In cross-domain access control,different users or applications may submit access requests with varying attribute specifications based on their respective needs and permissions.Traditional cross-domain access control methods fail to effectively handle these differentiated attribute specifications,resulting in inefficient access control operations and reduced precision.Therefore,this paper proposes a cross-domain access control method for grid enterprise data based on blockchain technology.It constructs a logical architecture for cross-domain access control of grid enterprise data using blockchain technology.Within this architecture,blockchain modules preprocess original access requests and transform access request information into a form based on attribute sets.Based on the attribute specifications of the access request information,the grid enterprise data undergoes primary and secondary mapping processes.The results of these mapping processes are combined to determine the attribute sets covered in the standard attribute table of the grid enterprise database,thereby providing corresponding data to users from different domains and achieving data cross-domain access control.Experimental results demonstrate that the interoperability mean value of this method consistently remains at a high level,stabilizing around 0.95.Moreover,the accuracy of cross-domain access control of grid enterprise data ranges between 96％and 98％,indicating effective performance.
