Demo Abstract: An Industrial Control System Testbed for the Encrypted Controller

The encrypted controller is a novel and promising approach for enhancing the security of industrial control systems [1]. This approach encrypts both the signals that transmitted over communication channels and the control law, so as to protect all information of a plant and its controller from attackers. However, in spite of considerable research efforts [2]-[12], the encrypted controller is still quite far from its implementation and application in industrial control systems. In-depth experimental studies are necessary for bridging the gap between theory and application of the encrypted controller. In this demonstration, we present an industrial control system testbed for experimental studies of the encrypted controller. Moreover, we carry out an experimental study that improves and evaluates the security of the industrial control system which comprises the encrypted controller using the testbed.
