Abstract
An apparatus includes a first distributed control system (DCS) node. The first DCS includes at least one interface configured to communicate, over a network, with a second DCS node. The first DCS node also includes at least one processing device. The processing device is configured to exchange a security association policy with the second DCS node. The processing device is also configured to exchange public keys with the second DCS node using the security association policy. The processing device is also configured to send a public key of the second DCS node to a field programmable gate array of the first DCS node. The processing device is also configured to receive a shared secret from the field programmable gate array. The processing device is also configured to generate a hash of a message using the shared secret.
