Design And Detection Of Hardware Trojan Horse Based On FPGA

Because of globalization of the semiconductor design and fabrication process, integrated circuits are becoming increasingly vulnerable to malicious activities and alterations. Integrated circuits are vulnerable to hardware Trojans, which risk to chips and hardware, either during design or fabrication. The Hardware Trojan technology has raised serious concerns and become a new research focus.In this paper, design and detection of hardware Trojan horse are based on FPGA, designed a variety of hardware Trojan horse, and finished the hardware design of test system. In this paper, the author firstly summarized the significance of this research work, the current research status of hardware Trojan, and analyzed the characteristic of hardware Trojan, the classification and the detection methods of hardware Trojan, and introduced the future trends of hardware Trojan. Next, some Combinational and sequential Trojan circuits are designed, and successfully passed the functional simulation and FPGA verification. Further, the hardware design of test system was achieved , the detection method and the test system was improved continually, data processing methods were discussed in detail,the key technique and the realization of each function in this system were introduced and analysed.Finally, the article summarized the design shortcomings and defects..The contributive points of this dissertation are:First,designed some hardware Trojans according to the characteristic and the architecture of IP core , proposed the design ideas and the design method of hardware Trojan. Second, hardware Trojans detected by the hardware test system based on the Current sensing resistor, proved that based on the power of the side-channel signal analysis is feasible , and then proposed the ideas and methods about the automatic test system test the side-channel signal.
