Abstract

Closed loop control systems have been implemented to conduct a variety of tasks (e.g. manufacturing and automation). Industrial Control System (ICS) have been used to regulate a closed loop process; however, ICS are exposed to the same security vulnerabilities associated with enterprise networks. Cryptography has been deployed to overcome the associated data communication weaknesses between each ICS node through the use of block ciphers; however, the drawback of applying cryptographic algorithms to ICS is the additional communication latency. This paper
investigates the relationship between security constructs and latency for closed loop control system with test conducted in a simulated environment. A case scenario is illustrated to demonstrate the impact of the results obtained to a real world context.
