| Abstract: |
| With the increasing complexity of IC design and fabrication, IC design and fabrication is endangered by potential threat like the inserted Hardware Trojan. Hardware Trojan may change the function of system, lead to the leakage of important information, damage the system or cause denial of service. This paper introduces the background, concepts and properties of Hardware Trojan. And then it analyzes the research status at home and abroad. Combined with cases of Hardware Trojan, this paper introduces its common classification, the general detection methods as well as their advantages and disadvantages. What's more, it applies typical cases to illustrate the features of each safety measure of Hardware Trojan. Finally, it puts forward the research direction and emphasis of Hardware Trojan after summarizing the existing problems in current researches. |
