Hardware Trojan Threat and Its Countermeasures

Hardware Trojan (HT) is a new threat in the embedded system domain. It is malicious modification of a design during its conception flow. Once inserted, it can create many critical attacks on a system. Therefore, HT inserted in integrated circuits have received special attention of researchers. In this paper, we will first introduce the concept of HT. Then, we will give a summary of HT detection methods including optical methods, testing methods, Side-Channel methods. Finally, we will focus on the Side-Channel methods and our perspectives for the future work.
