Detection of replay attacks in smart grid systems

Smart grid has many advantages compared with the traditional power grid, and will soon become new infrastructure for power generation, delivery, and management. However, beside those positive promising, security for smart gird has been emerging as an important issue, since the smart grid will be a combination of many kinds of systems and security protocols that cover the whole system are still not complete. In this paper, we focus on replay attacks, which could be one of the most popular security attacks in smart grid systems. In particular, we propose a new detection scheme for replay attacks based on a solution originally developed for a control system.
