用于硬件木马检测的电磁辐射分析方法研究

Research on electromagnetic radiation based side-channel analysis method for hardware Trojan detection

随着集成电路产业全球化的发展,硬件木马已成为集成电路的主要安全威胁之一。目前能较好权衡检测成本与检测能力的侧信道分析方法越来越受到研究人员的关注,其中,电磁辐射分析方法是研究热点之一。重点分析并验证电磁辐射分析方法对硬件木马的检测能力,并探究限制其检测性能的原因。在现场可编程逻辑门阵列(FPGA)上进行验证实验,实验结果表明,电磁辐射分析方法可以很好地检测电磁辐射频率分布独特的硬件木马电路,但无法适用于电磁辐射频率分布复杂的硬件木马。

With the globalization of the integrated circuit industry,hardware Trojan is becoming the main threat to integrated circuits.At present,the side-channel analysis which can make a good trade-off between detection ability and cost,has attracted more attention from the academia.The side-channel analysis method based on electromagnetic radiation is one of the hotspots in hardware security field.The ability evaluation of electromagnetic radiation analysis method to detect hardware Trojan was focused,and the factor that limited their detection performance was explored.The experimental results on FPGA show that the electromagnetic radiation analysis method can effectively detect hardware Trojan whose electromagnetic radiation distribution is significantly different from surrounding circuits,but it cannot be applied to hardware Trojan with complex frequency distribution of electromagnetic radiation.
