Hardware Trojan Horses have emerged as great threats to modern electronic design and manufacturing practices. Because of their inherent surreptitious nature, test vector generation to detect hardware Trojan horses is a difficult problem. Efficient online detection techniques can be more effective in detection of hardware Trojan horses. In this paper, we propose a low-overhead detection technique which inserts malicious logic detection circuitry at netlist sites chosen by an algorithm that employs an intelligent and accurate analysis of fault propagation through logic gates. Proactive system-level countermeasures can be activated on detection of malicious logic, thereby avoiding disastrous system failure. Experimental results on benchmark circuits show close to 100 percent HTH detection coverage when our proposed technique is employed, as well as acceptable overheads.
