The Study of Hardware Trojan Detection Based on Reference Curve
-
Abstract
Currently the main detection approaches to the Hardware Trojan are logical test and side-channel analysis, however, these methods suffers from decreased sensitivity toward small Trojans and large process variation. In this paper, we take advantage of the intrinsic relationship between dynamic current and maximum operation frequency of the circuit to formulate a reference curve, then compare the measured curve with the reference curve to detect the Hardware Trojan. At the beginning we use the Synopsys tool to validate the theory, then design specified PCB test board, choose the appropriate measure device and FPGA to set up the test system. The test result shows that this system can reduce the influence of the process variation on the detect result efficiently and improve the detection accuracy.
