A Wide-Area Measurement System (WAMS) is a system that provides a time-synchronized view of electrical conditions over a large geographical area, thereby enhancing the situational awareness of the energy management system of a power grid. With this enhanced situational awareness, utilities would be able to react promptly to contingencies, and prevent large-scale blackouts. To secure WAMS communications, the authors propose WAMS KEy management (WAKE), a comprehensive key management scheme targeting a concrete set of security objectives derived from NIST's security impact level ratings.
