Towards enhancing trustworthiness of wireless integrated circuits, this project investigates the problem of hardware Trojans in the analog/RF domain. Hardware Trojans are maliciously-intended modifications to fabricated integrated circuits, making them capable of additional functionality which is unknown to the designer and user, but which can be exploited by the perpetrator after chip deployment to sabotage or incapacitate it, or to steal sensitive information. The motivation for this research is two-fold: First, partly because of design outsourcing and migration of fabrication to low-cost areas across the globe, and partly because of increased reliance on external intellectual property and design automation software, the integrated circuit supply chain is now considered far more vulnerable to such malicious modifications than ever before. Second, wireless integrated circuits constitute an indispensable part of modern electronic systems and their ability to communicate data (possibly encrypted) over public channels makes them a prime attack candidate. To address this problem, this project focuses on (i) delineating the threat and potential impact of hardware Trojans in wireless cryptographic ICs, (ii) elucidating the shortcomings of existing test methods in exposing them, (iii) developing preventive countermeasures for obfuscating the chip design and complicating the development of hardware Trojans, and (iv) devising efficient hardware Trojan detection methods based on statistical analysis and machine learning. The anticipated impact of this research lies in the attainment of a better understanding of the hardware Trojan threat and in the development of appropriate remedies, thus enabling secure deployment of wireless integrated circuits and fostering technology trustworthiness.

为了提高无线集成电路的可信度，本项目研究了模拟/RF域中的硬件木马问题。硬件特洛伊木马是对制造的集成电路进行恶意修改，使其具有设计者和用户未知的额外功能，但可以在芯片部署后被犯罪者利用来破坏或使其丧失功能，或窃取敏感信息。这项研究的动机是双重的：首先，部分是因为设计外包和制造迁移到地球仪的低成本地区，部分是因为越来越依赖外部知识产权和设计自动化软件，集成电路供应链现在被认为比以往任何时候都更容易受到这种恶意修改。其次，无线集成电路构成了现代电子系统不可或缺的一部分，并且它们通过公共信道传送数据（可能加密）的能力使它们成为主要的攻击候选者。为了解决这个问题，本项目的重点是（i）描述无线加密IC中硬件木马的威胁和潜在影响，（ii）阐明现有测试方法在暴露它们方面的缺点，（iii）制定预防对策，以混淆芯片设计和使硬件木马的开发复杂化，及（iv）基于统计分析及机器学习设计有效的硬件木马侦测方法。这项研究的预期影响在于更好地了解硬件特洛伊木马威胁，并制定适当的补救措施，从而实现无线集成电路的安全部署，并促进技术的可信度。
