摘要
随着集成电路设计制造的全球化,芯片存在被植入硬件木马的隐患.目前的硬件木马检测方法中,逻辑测试激活硬件木马的概率较低,侧信道检测受电路工艺偏差、硬件木马面积影响较大.本文提出基于激光注入的硬件木马检测方法,通过诱发数据翻转主动激活硬件木马触发逻辑,同时可以定位硬件木马触发逻辑的物理位置.采用1064 nm皮秒脉冲激光成功激活了基于FPGA的异步累加器型硬件木马.研究表明对于具有逻辑触发结构的硬件木马,激光注入方法与硬件木马的触发条件无关.通过设计高覆盖率的注入方式,能够高概率的激活硬件木马.
With the development of integrated circuit design,there is a hidden threat of chips implanted by hardware Trojan.In the previous research of hardware Trojan detection,the detection rate of the logic test detection method is low,and the side channel detection method are affected by the low trigger rate of the hardware Trojan seriously.This paper proposes a novel approach to activate the hardware Trojan based on the laser injection.The physical location of the hardware Trojan can be located.The FPGA-based asynchronous accumulator hardware Trojan was activated by 1064 nm picosecond pulse laser successfully.The results show that the laser injection method has nothing to do with the trigger condition of the hardware Trojan with the logical trigger structure.By designing a high coverage rate injection method,the hardware Trojan can be activated with high probability.
