摘要

芯片后门指令是激活硬件木马的典型方式之一，其安全风险高，影响范围广，且难于检测.本文提出了一种基于能量分析的后门指令检测方法，通过对指令分段穷举、并分别采集其能量信息，可有效区分常规指令和后门指令.实验表明，通过简单能量分析即可从能量迹中直接判定出后门指令.进一步，本文提出了一种自动化识别后门指令的相关能量分析方法，通过判断其相关系数与系数均值之间的关系，可高效、自动地完成后门指令分析.

Abstract

The backdoor instruction of chip is one of the typical ways to activate hardware Trojan

which has high security risk and a wide range of impact besides being difficult to be detected.In this paper

we propose a detection method of the backdoor instruction based on power analysis technology.By utilizing the segmented exhausting process and some power traces

the backdoor instruction can be distinguished from the conventional instruction effectively.The experiments show that the backdoor instruction can be analyzed successfully from the power traces by simple power analysis (SPA).Moreover

we also present an automatic detection method for the backdoor instruction based on correlation power analysis (CPA).By comparing the correlation coefficient with the mean value of the coefficient

backdoor instruction can be analyzed efficiently and automatically.
