Hardware Trojans Detection Based on Electromagnetic Emission Signals Analysis
Zhang Pen · 2014
Integrate circuits(ICs)may be inserted malicious circuits as a hardware Trojan during fabrication.A novel hardware Trojans non-destructive detection technique using the electromagnetic side channel signals of chips is proposed.The technique includes two steps.Firstly,the surface of chip is divided into smaller sub-blocks,and a suitable input vector set is generated with a special selection algorithm.Secondly,based on the projection pursuit withnegative entropy index,the detector could find out the data structure enables reflect high dimension special rules without obvious information loss,so as to attain the goal of feature abstraction and identification onside channel signals ofIC chips.The detection experiments against an exemplary AES-128 hardware Trojan circuit showed that the technique proposed in this paper could distinguish the difference of side channel signal's feature between the genuine chip and tested chip,and consequently could detect the existence of the hardware Trojan.
