The Smart Grid Access Control Research Based On Cloud Storage

The smart grid is the future development trend of the power grid; the informationplatform is the important basis for the construction of the smart grid. The data will bemore and more while the development of power grid, the traditional information platformmay have been unable to meet the demand in the future. And the value of massive datafor the monitoring and maintenance also will be more and more valuable. The cloudstorage system has obvious advantages of storing and sharing massive data, the skill ofdata access control is focal and difficult issues when we research the smart grid cloudstorage system with massive data. For the characteristic of this system, we design ascheme with stratified data which can be implemented in cloud storage architectureprototype system based on HDFS (Hadoop Distributed File System). then data can beencrypted by CP-ABE encryption scheme, the visitors can get their private keysaccording to their property values, and only do visitors’ attribute match the policy theycan get the data, by this way, the attacks which from internal system can be avoided,meanwhile the access control policy can make the data sharing process easier, canprovide a more fine-grained access control, so that rights management turns into propertymanagement, we can get an easier way to manage rights. Experimental results show thatthe scheme can isolate smart grid data between cloud storage system efficiently andsafely.
