Detecting Hardware Trojans in IC Chips with Side Channel Analysis

针对密码芯片中硬件木马电路检测的困难性,介绍了根据芯片旁路信息进行硬件木马检测的思想.在形式化定义基于旁路分析的硬件木马检测问题的基础上,分析了含硬件木马与不含硬件木马的密码芯片对应旁路信号在主成份分析结果上的差异,并以此对FPGA实现的含硬件木马的DES密码原型芯片进行了检测实验,实验结果表明了基于旁路信号主成份分析在密码芯片硬件木马检测中的效果.

Aimed at the difficulty in detecting hardware Trojans inside IC chips, a novel idea about detecting Troian circuits with side channel analysis is introduced. After formally defining the problem of detecting hardware Trojans in IC chips with side channel analysis, the differences between principle components analysis on side channel signals acquired from chips with Trojan circuits and without Trojan circuits were analyzed. Detection experiments with principle components analysis were taken out on a DES cipher chip implemented on a FPGA board. The results of experiments verified the effect of Hardware Trojans detection with principle components analysis on side channel signal.
