Abstract: For the chip power consumption data acquisition when the influence of the noise problem, this paper proposes a multiple sidechannel analysis method based on correlation analysis, using the intrinsic relationship between dynamic current and electromagnetic radiation to identify the existence of hardware trojans. A dual channel detection platform is built to simultaneously collect and store the dynamic power consumption and electromagnetic radiation of the chip. Pearson correlation coefficient curves of power consumption and electromagnetism are obtained to distinguish hardware Trojan horse chip from hardware Trojan horse chip. The experimental results show that the hardware Trojan detection method based on multipleparameter sidechannel analysis can screen out the chip containing hardware Trojan whose area is only 0.28% of the chip to be tested, and can distinguish the two hardware Trojan horses whose area difference is only 0.08% of the chip to be tested.
