Improving Resilience by Deploying Permuted Code onto Physically Unclonable Unique Processors

Industrial control systems (ICSs) are, at present, extremely vulnerable to cyber attack because they are homogenous and interconnected. Mitigating solutions are urgently required because systems breaches can feasibly lead to fatalities. In this paper we propose the deployment of permuted code onto Physically Unclonable Unique Processors in order to resist common cyber attacks. We present our proposal and explain how it would resist attacks from hostile agents.
