Hardwareobfuscation is a technique by which the description or the structure ofelectronic hardware is modified to intentionally conceal thefunctionality of the hardware. In essence, it is different from digitalwatermarking, or from hardware intellectual property watermarking wherethe ownership information is concealed in the behavior of the circuitbut little effort is made to conceal the actual functionality of thecircuit. It is also different from cryptography-based IP protectiontechniques common in field programmable gate array based designmethodologies. The importance of the techniques of hardware watermarkinghas increased in the recent years due to the widespread adoption ofhardware IP based design practices for cutting edge integrated circuitssuch as system on chips. This is because of three main threats: hardwareintellectual property infringement from the SoC design houses and/ortheir associates; the possibility of reverse engineering the IC designdatabase in fabrication facilities or the manufactured ICs themselves toproduce counterfeit ICs.…
