Power grids connect electricity producers to consumers through interconnected transmission and distribution networks. In these networks, system monitoring is necessary to ensure reliable power grid operation.

The analysis of smart meter measurements and power system models that estimate the state of the power grid are a routine part of system monitoring.

False data injection attacks exploit the configuration of power grids by introducing arbitrary errors into state variables while bypassing existing techniques for bad measurement detection.

nCircle announced the results of a survey of 104 energy security professionals. When asked, “Do smart meter installations have sufficient security controls to protect against false data injection?” 61% said “no”.
