Cybersecurity is an important component for any electric utility network device. PMI devices such as the Cell Guardian, Revolution, and Boomerang (Figure 1) generate data from raw voltage and current measurements. This data is sent to cloud-based PQ Canvass, Canvass, or PC-based ProVision using a complex, multilayered communications network that includes several types of channels. Cybersecurity is ensured with different mechanisms of authentication and encryption, providing an end-to-end secure link. The RF link is unique in the chain due to the cell standards requirements and physical layer transport. Here the cybersecurity features of the RF cellular link between the device and the cell tower are reviewed in detail.
