英文摘要：

On the basis of studying the essence of clock fault injection attack ,the critical path replica‐tion detection circuit was improved and then a new clock fault injection attack detector mode which can be implemented on different platforms was proposed in this paper .The circuit detected the system fault injection attack by detecting the delay on transmission path .T he circuit can effectively detect at‐tacks by copying working path and adding redundancy logic and is easily achieved in ASIC （application specific integrated circuit ） and FPGA （freld programmable gate aray ） .Based on the actual situation , detection sensitivity can be designed reasonably ,which makes the detector more adaptable .Some overclocking detection experiments were done to verify the performance of the detector .And the re‐sults show that the detector is flexible and effective .
