A Start to Fail Frequency Technique for Detecting Hardware Trojan

Rapid development of portable devices plays a major role in communication sector, which has led to a significant concern for cryptology. Cryptographic circuits are vulnerable to various side-channel attacks by the hardware Trojan horses (HTHs). HTHs are the malicious design modification that either alters the actual behavior of the design or reveals the secret information. In this work, we proposed a technique which is elusively for detection of hardware Trojans based on Start to Fail (STF) frequency concept. We inferred that this detection technique is efficient based on the experimental results observed, using ISCAS benchmark circuits and scalable encryption algorithm (SEA).
