The survey of Wireless Sensor Networks information security in Smart Grid

This paper discusses the application of wireless sensor network in the smart grid and information security requirements, such as confidentiality, integrity, availability, and data freshness. We also analyze the physical attack and several typical network attacks of WSNs in smart grid. We elaborate the implementation process, characteristics and the hazards to the power grid of these attacks. In the paper, we propose a communications security policy of WSNs in smart grid and corresponding information security technologies, we analyze the characteristics and existing solutions of such information security technology, then we propose corresponding solutions of security technology applicable to smart grid. In the end, we summarize some issues in the realization of WSNs security technologies in smart grid and discuss the latest trends.
