An Automatic Fault Injection Analysis Method Against FPGA Bitstream
Shanghai Fudan Microelectronics Group Co., Ltd, Shanghai, China.
ABSTRACT
Common fault injection attacks against FPGA (Field Programmable Gate Array) bitstream typically require attackers to be very familiar with the specific correspondence of the target FPGA between the internal structure and the bitstream. However, it is very difficult and impractical to reverse the bitstream. This paper proposes an automated FPGA bitstream fault injection analysis method that does not require bitstream analysis. It also conducts voltage fault injection experiments for the first time using Spider on Xilinx-7 series FPGA development boards. Experimental results show that 480 erroneous ciphertexts are sufficient to obtain the AES(Advanced Encryption Standard)-128 key.
Keywords: FPGA security, Automated fault injection, Persistent fault analysis.
