Physical unclonable function - Wikipedia A PUF is a physical entity embodied in a physical structure PUFs can be implemented in integrated circuits, including FPGAs, [4] and can be used in applications with high-security requirements, more specifically cryptography, Internet of things (IOT) devices [5] and privacy protection [6]
Advances in Physical Unclonable Functions Based on New . . . - MDPI In particular, we first provide an insightful overview of four types of PUFs that are rooted in advanced technologies: bionic optical PUF, biological PUF, PUF based on printed electronics (PE), and PUF based on memristors
Physical Unclonable Functions (PUF) for IoT Devices Physical Unclonable Function (PUF) has recently attracted interest from both industry and academia as a potential alternative approach to secure Internet of Things (IoT) devices from the more traditional computational-based approach using conventional cryptography
