Abstract

With the large-scale application of advanced information and communication technologies such as wireless communication and Internet of Things in the smart grid, the threat of viruses, Trojans and hackers from the Internet is becoming more and more serious. Compared with the traditional power grid, the more complex access environment, flexible access methods and a large number of access terminals in smart grid bring new challenges to data security protection. Existing data encryption and access control schemes are difficult to meet the actual needs of data leakage prevention in all aspects of smart grid. This paper proposes a smart grid data leakage prevention system architecture based on label and strategy, focusing on the design and implementation of data leakage prevention system for smart grid from the perspective of unified data management platform, terminal and network data leakage prevention. The system design architecture and scheme proposed in this paper can help solve the data security protection of smart grid data from transmission to storage, and has important practical reference value.
