This book presents advanced forensic detective control and obfuscation techniques for securing hardware IP cores by exploring beyond conventional technologies. The theme is important to researchers in various areas of specialization, because it encompasses the overlapping topics of EDA-CAD, hardware design security, VLSI design, IP core protection, optimization using evolutionary computing, system-on-chip design and finally application specific processor/hardware accelerator design for consumer electronics applications. The book begins by introducing forensic detective control and obfuscation mechanisms for hardware and IP core security. Further chapters cover hardware stenography, digital signature driven hardware authentication, fault-secured IP cores using digital signature-based watermarks, multi-level watermarking, cryptosystem-based multi-variable fingerprinting, multi-phase and hologram-based obfuscation, and security of functionally obfuscated DSP cores.
