Physical unclonable functions (PUFs) have emerged as a favorable hardware security primitive, they exploit the process variations to provide unique signatures or secret keys amidst other critical cryptographic applications. CMOS-based PUFs are the most popular type, they generate unique bit strings using process variations in semiconductor fabrication. However, most existing CMOS PUFs are found to be vulnerable to modeling attacks based on machine learning (ML) algorithms.

- Physical Unclonable Functions (PUFs) are cryptographic tools that leverage inherent randomness from manufacturing variations to create secure applications, with the latest advancements highlighting memristor-based PUFs as more robust against attacks.
- The research focuses on developing a cost-effective memristor PUF that passes 15 NIST randomness tests, demonstrating properties like uniqueness, uniformity, and repeatability, while also being compatible with CMOS technologies.
- The paper also explores the memristor PUF's application in enhancing encryption processes and in a new authenticated key exchange protocol for secure communications in advanced metering infrastructures used in smart grids.
