Abstract
A controller for an electric power distribution system includes processing circuitry and a memory that includes instructions. The instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to determine that a first switch of the electric power distribution system is a primary switch communicatively coupled to an intelligent electronic device (IED) of the electric power distribution system, determine that a second switch of the electric power distribution system is a backup switch communicatively coupled to the IED, and distribute a first copy of a security association key (SAK) to the first switch and a second copy of the SAK to the second switch in response to determining that the first switch is the primary switch and the second switch is the backup switch to enable the first switch and the second switch to establish respective media access control security (MACsec) communication links with the IED.
