Data Security in the Smart Grid Environment

We present a taxonomy of various smart grid domains based on the National Institute of Standards and Technology (NIST) framework for the smart grid (SG) environment. Since communications in the SG environment use various wireless technologies, there is a high possibility that a malicious adversary can intercept, modify, delete, and interrupt the transmitted messages between the communicating entities. In addition, smart devices in the SG environment can also be physically compromised by an adversary. Therefore, in this chapter we develop a taxonomy on various security protocols aimed at the SG environment, which includes key management, authentication, access control, trust computing, privacy-preservation, and intrusion detection systems. We discuss the threat model and various security requirements as well as attacks related to the SG environment. Next, we present various security solutions based on the taxonomy of security protocols we have developed. Finally, we discuss various security platforms that are deployed and implemented in the SG environment.
