SYSTEMS AND METHODS FOR USING ENTROPY DATA IN AN ELECTRIC POWER DISTRIBUTION SYSTEM

A system includes an entropy device configured to generate and distribute input entropy data and an intelligent electronic device (IED) of an electric power distribution system. The IED is configured to perform operations that include receiving the input entropy data distributed by the entropy device, generating a set of keys using the input entropy data, and establishing a Media Access Control Security (MACsec) communication link using the set of keys.
