硬件木马检测与防护

Hardware Trojans detection and protection

第三方技术服务的普及使得在集成电路(IC)设计制造过程中,芯片可能被恶意植入"硬件木马",给芯片的安全性带来了极大挑战,由此,如何检测"安全芯片"中是否存在硬件木马,确保芯片的安全性开始受到人们的广泛关注。在简要介绍硬件木马概念及其危害的基础上,分析硬件木马的特点和结构,介绍了当前现有的几种硬件木马检测技术,给出了硬件木马检测技术的科学分类,重点分析了这些检测方法所面临的问题和挑战并提出了相应的改进措施,总结了未来硬件木马防测技术的发展趋势。

With the popularity of third-pariy technical services, chips may be maliciously implsnted hardware Trojans during the IC design and manufacturing process, which brings a major challenge for chip security. So how to detect the existence of hardware Trojans and ensure the security of chips gradually has attracted wide attention. This paper briefly introduces the concept and harm of hardware Trojans. Then we analyse the characteristics and structural features of hardware Trojans, in- troduce currently existing hardware Trojan detection technology, give the classification of hardware Trojan detection technol- ogy, especially the problems and challenges faced by current detection methods, and put forward the corresponding im- provelnent lneasures. At last we stun up the future research trends of hardware Trojan prevention and detection technology.
