AR-PUFs: Advanced Security Primitives for the Internet of Things and Cyber-Physical Systems

In this work, we examine very briefly a number of Advanced Reconfigurable Physical Unclonable Functions (AR-PUFs) that can be used to enhance the security of devices used for the realisation of the Internet of Things (IoT) and Cyber-Physical Systems (CPS). To this end, we also present two practical lightweight protocols that can be implemented using such AR-PUFs on IoT and CPS devices, in order to significantly enhance their security, even allowing the security of such devices to be restored after they have been compromised
