This book discusses the design principles of physically unclonable functions (PUFs) and how these can be employed in hardware-based security applications, in particular, the book:Provides readers with a comprehensive overview of security threats on embedded systems and existing countermeasures, Includes an intensive tutorial on how to design and evaluate physically unclonable functions, supported by circuit diagrams and exemplar hardware implementations, Discusses the reliability challenges facing PUF technology and explains in details the state of the art mitigation approaches adopted, including those based on error correction codes and/or pre-processing techniques, Gives a comprehensive tutorial on the security threats facing PUF technology, including modelling attacks using machine learning algorithms, side channel analysis, and physical attacks. It also outlines possible countermeasures and defence mechanisms, Explains in detailed the practical applications of PUF technology, these include secure cryptographic key generation and storage, hardware-assisted security protocols,  low cost secure sensors, anti-counterfeit integrated circuits and anti-tamper hardware. 







This book has many features that make it a unique source for students, engineers and educators, including more than 80 problems and worked exercises, in addition to, approximately 200 references, which give extensive direction for further reading.
