A security method of hardware Trojan detection using path tracking algorithm

Abstract Recently, the issue of malicious circuit alteration and attack draws more attention than ever before due to globalization IC design manufacturing. Malicious circuits, also known as hardware Trojans, are found able degrade performance or even leak confidential information, accordingly it is definitely an immediate concern develop detection techniques against Trojans. This paper presents a ring oscillator-based technique improve Trojan performance. A under test divided into great number blocks, path assignment optimized using tracking algorithm, high coverage reached accordingly.
