Hardware Trojan Detection Techniques Using Side-Channel Analysis

Hardware Trojan (HT) is a malicious modification of the integrated circuits during design or fabrication processes. It can extract the secret information or change the circuit behavior. Many HT detection techniques have been proposed in recent years. This paper focuses on side channel analysis (SCA) based approach due to its advantages over other approaches. We review the state-of-the-art researches, present a proposed path delay based SCA method and discuss the trend for developing new HT detection techniques in the future.
