Abstract

Several key factors drive the exploration of PUFs across multiple layers of CPS: rising cybersecurity threats, unique security challenges of CPS, the need for holistic security approaches, scalability, and interoperability. The key objectives and purposes of this analysis include: comprehensive vulnerability assessment, understanding cross-layer dependencies, ensuring device-level security, and preparing for future threats. Physically Unclonable Functions (PUFs) with Computer-Aided Design (CAD) are used for the design, analysis, and verification of electronic systems. PUF designers may utilize CAD tools for designing and simulating PUF circuits. PUFs are investigated for their integration into Cyber-Physical Systems (CPS) to address security challenges in the convergence of physical and digital components. Cross-layer analyses and evaluations aim to understand how PUFs can contribute to the overall security posture of CPS. Here are several domains and disciplines where the findings and implications of this study can be applied: Cybersecurity, Embedded Systems Design, Cryptography, Computer Engineering, IoT (Internet of Things), Information Security, Systems Engineering.
