Review on Hardware Trojan Detection Techniques

As a result of globalization, chip design and manufacturing are becoming more susceptible to harmful actions and modifications. However, to develop a reliable and effective system there should be no role of hardware Trojan. In microelectronic systems, hardware security plays a vital role. Hardware security as a discipline originated out of cryptography and involves hardware design, and secure multi-party computations. Hardware Trojan (HT) is a major threat to hardware security because HT can change the circuit's behavior and leak the information, once it is activated. To improve the reliability of the system and the trust of the circuits HT should be detected. This paper deals with various hardware trojan identification like pre-silicon design stage-based detections and post-silicon fabrication stage-based detections.
