Outline of Final Research Achievements

In recent years, several researches for hardware Trojan and its detecting method are becoming to active rapidly.The hardware Trojan is implanted as hardware modification to conventional LSIs. After a trigger, which is an activate signal to satisfy event condition occurs, hardware Trojan-implanted chips are modified the original function to enable an adversary to control, monitor, communication and so on. Thus, an adversary can disable or destroy a system, or the Trojan can leak confidential information and secret keys convertly to the adversary.
In this research, a verification board, which can execute the ARM-based SOC processing, is developed with a CPU and a FPGA. Especially, a hardware Trojan, which is implanted the cryptographic triple DES and AES circuits, is implemented in a Xilinx FPGA and is able to leak plain text and a secret-key after encrypting processing.
