Abstract
An industrial control system includes an encryption device, a decryption device and a mission-critical communication link connecting the encryption device to the decryption device. The encryption device is configured to send encrypted messages to the decryption device over the mission-critical communication link. The system includes a failure monitor configured to monitor for a failure of the encryption device or the decryption device, and, in the event of failure, to continue the sending of the messages to the decryption device but without encrypting the messages.
