The Silicon Biometric explores the critical shift from traditional, memory-based encryption to hardware-intrinsic security within the global semiconductor supply chain. As the Internet of Things (IoT) expands, static cryptographic keys stored in non-volatile memory have become vulnerable to sophisticated physical probing and cloning. This book introduces Physically Unclonable Functions (PUFs) as a transformative solution, leveraging spontaneous, microscopic manufacturing variations—such as threshold voltage and carrier mobility—to create a unique "silicon biometric" for every chip. Spanning six chapters, the text bridges the gap between materials science and cryptographic logic. It provides a deep dive into architectural implementations, including CMOS-based Arbiter PUFs, SRAM power-up states, and emerging RRAM technologies. Crucially, the work addresses the engineering challenge of system reliability, detailing how Error Correcting Codes (ECC) and Fuzzy Extractors stabilize noisy analog properties into secure digital secrets. It is an essential resource for VLSI scientists and cybersecurity practitioners securing the next generation of embedded electronics.
