Data Security Isolation and Exchange for Smart Grid

Abstract

With the arrival of the big data era, data security is getting more and more important especially in many critical fields such as smart grid. At the same time of requiring strict data isolation, it also needs to exchange a lot of data between different security zones. How to implement the smooth data isolation and exchange becomes the focus of numerous data security researchers. Aiming at the data security requirement of smart grid, this paper designs a data security isolation and exchange scheme to ensure the data security in smart grid. The proposed scheme includes three modules: internal network host processing unit, data isolation and exchange unit and external network host processing unit, and provides four functions: user identity authentication, data access control, protocol stack parsing and SQL statement filtering. The implement details of four functions are elaborated. The data security isolation and exchange scheme provide a very useful means to enhance the data security of smart grid.
