Abstract – With the advent of Very large Scale Integration (VLSI) in the semiconductor industry, Integrated Circuits (ICs) have dominated the design of electronic circuits which have intensively formed an integral part in design of safety critical and safety related electronic circuits used in nuclear reactors. One weak link during the design, fabrication and packaging of these Integrated Circuits (ICs) is the inclusion of Hardware Trojans which is an alteration / inclusion of components in the IC during the IC design life cycle intentionally by an adversary to impede the functionality of these ICs during its course of operation. These hardware Trojan effected ICs can get triggered like a time bomb during operation of the ICs and alter the functionality of the ICs leading to unavailability of the safety critical electronic circuits. These hardware Trojans are very difficult to detect if also complete verification and validation of these ICs are done and hence special Trojan detection techniques and design life cycle restrictions have to be imposed on these ICs to prevent / detect hardware Trojans. This paper focuses on describing the IC design life cycle and vulnerable areas prone to security threats, hardware Trojan Taxonomy and actions, Literature study of Hardware Trojan prevention and detection techniques and a regulatory perspective of the issue.
