The key server communicates the authorization information to the IED, via a Media Access Control Security (MACsec) Key Agreement (MKA) protocol to allow the IED to authenticate the user. The key server receives one or more commands from the user. The key server communicates the one or more commands to the IED to allow the IED to perform operations based on the one or more commands.
