Abstract

Cloud computing enables resource-constrained Networked Control Systems (NCSs) to outsource heavy computations to a cloud server with massive computational resources. However, Cloudenabled NCSs (CE-NCSs) introduce new challenges arising from the trustworthiness of the cloud and the cyber-physical connections between the control system and the cloud. To address these concerns, this paper presents a secure and resilient mechanism, which employs customized cryptographic tools to encrypt the data of a control problem and develops verification methods to guarantee the integrity of the computational results from the cloud. In addition, our design enables a Switching Mode Mechanism (SMM) to provide resiliency to the NCSs when the system successively fails to receive correct control inputs from the cloud. We demonstrate that the mechanism can achieve the data confidentiality and integrity, guarantee the stability, and enhance the resiliency. Finally, an Unmanned Aerial Vehicle (UAV) example is used to corroborate these properties.
