Book excerpt: This book provides a comprehensive coverage of hardware security concepts, derived from the unique characteristics of emerging logic and memory devices and related architectures. The primary focus is on mapping device-specific properties, such as multi-functionality, runtime polymorphism, intrinsic entropy, nonlinearity, ease of heterogeneous integration, and tamper-resilience to the corresponding security primitives that they help realize, such as static and dynamic camouflaging, true random number generation, physically unclonable functions, secure heterogeneous and large-scale systems, and tamper-proof memories. The authors discuss several device technologies offering the desired properties (including spintronics switches, memristors, silicon nanowire transistors and ferroelectric devices) for such security primitives and schemes, while also providing a detailed case study for each of the outlined security applications. Overall, the book gives a holistic perspective of how the promising properties found in emerging devices, which are not readily afforded by traditional CMOS devices and systems, can help advance the field of hardware security.
