On Practicality of Using ARM TrustZone Trusted Execution Environment for Securing Programmable Logic Controllers

arXiv:2403.05448v1 Announce Type: new
Abstract: Programmable logic controllers (PLCs) are crucial devices for implementing automated control in various industrial control systems (ICS), such as smart power grids, water treatment systems, manufacturing, and transportation systems. Owing to their importance, PLCs are often the target of cyber attackers that are aiming at disrupting the operation of ICS, including the nation's critical infrastructure, by compromising the integrity of control logic execution. While a wide range of cybersecurity solutions for ICS have been proposed, …
