Abstract: In one embodiment, a supervisory device for a network of a power substation identifies a plurality of nodes in the network of the power substation. The supervisory device associates each of the nodes with one or more security certificates. A particular security certificate authenticates a particular node to the supervisory device and authorizes the particular node to communicate in the network of the power substation. The supervisory device determines a security perimeter for the nodes in the network. The supervisory device schedules communications among the nodes using the one or more security certificates and based on the determined security perimeter.
