A Novel Architecture Against False Data Injection Attacks in Smart Grid
Smart Grid is a new type of power grid that will provide reliable, secure, and efficient energy transmission and distribution. Cyber attacks against data readmission system threaten the security of smart grid. Hence, identifying and preventing the false data injection as early as possible becomes a critical issue. However, there is no existing solution that considers all aspects such as deployment cost and system efficiency. In this paper, the authors apply a light-weight watermarking technique to defend against false data injection attacks. To be specific, they add a secure watermark to real-time meter readings and transmit the watermarked data through high speed unsecured network.
