Abstract (in Japanese) (See Japanese page) 
(in English) There have been reports of threats that cause information leakage by inserting Hardware Trojans (HT) into the connection lines around devices. In this threat, HT insertion is assumed not only at the stage of manufacturing, but also during the distribution and operation stage after shipment, and the threat may extend to devices that are not considered to be threatened by HT insertion implemented inside conventional ICs. This paper proposes a method for detecting HT insertion by measuring the changes in electrical characteristics caused by HT insertion using on-chip sensors. Specifically, HT insertion is detected by observing the change in capacitance associated with HT insertion using a capacitance sensor, and detecting the difference from the measurement result when HT is not inserted connection line. In the evaluation experiment, we build an evaluation environment based on the HT insertion method reported in previous studies and observe the change in capacitance on the connected line using an SoC equipped with a constant current source and A/D converter that constitute the capacitance sensor. Then, we show that HT insertion on the connecting line can be detected from the output values of the capacitance sensor before and after HT insertion.
