A major security threat to an integrated circuit (IC) design is the Hardware Trojan attack which is a malicious modification of the design. Previously several papers have investigated into side-channel analysis to detect the presence of Hardware Trojans. The side channel analysis were prescribed in these papers as an alternative to the conventional logic testing for detecting malicious modification in the design. It has been found that these conventional logic testing are ineffective when it comes to detecting small Trojans due to decrease in the sensitivity due to process variations encountered in the manufacturing techniques. The main paper under consideration in this survey report focuses on proposing a new technique to detect Trojans by using multiple-parameter side-channel analysis. The novel idea will be explained thoroughly in this survey report. We also look into several other papers, which talk about single parameter analysis and how they are implemented. We analyzed the short comings of those single parameter analysis techniques and we then show how this multi-parameter analysis technique is better. Finally we will talk about the combined side-channel analysis and logic testing approach in which there is higher detection coverage for hardware Trojan circuits of different types and sizes.

翻译：集成电路设计面临的主要安全威胁之一是硬件木马攻击，即对设计进行恶意篡改。此前已有数篇论文探讨了利用侧信道分析检测硬件木马的存在。这些论文将侧信道分析作为传统逻辑测试的替代方案，用于检测设计中的恶意篡改。研究发现，由于制造工艺中的工艺偏差导致灵敏度下降，传统逻辑测试在检测小型木马时效果不佳。本综述报告所重点研究的论文提出了一种基于多参数侧信道分析的新型木马检测技术。本综述报告将详细阐述这一创新思想。我们还考察了其他若干探讨单参数分析及其实现方式的论文。我们分析了这些单参数分析技术的不足，并进而论证了多参数分析技术的优越性。最后，我们将讨论结合侧信道分析与逻辑测试的方法，该方法对不同类型和尺寸的硬件木马电路具有更高的检测覆盖率。
