摘要

Due to their importance in modern critical infrastructure, industrial environments, and military platforms, programmable logic controllers (PLCs) must be protected from cyberattacks. This letter presents a quad-redundant architecture for PLCs to achieve cyber-resilience against hacking. Typical redundancy schemes for PLCs provide robustness against physical damage and random faults, but exhibit se...
