硬件木马防护研究综述

Survey on the Hardware Trojan Protection

硬件木马具有体积小、易实现、难防护等特点,是目前集成电路面临的主要安全威胁之一,如何保护集成电路不受硬件木马侵袭已日益成为各应用领域迫切需要解决的问题.分析了集成电路面临的3种安全威胁,介绍了硬件木马的概念,讨论了几种比较常见的硬件木马分类方法,在此基础上,从集成电路测试、设计、运行3个方面着重阐述了硬件木马的防护方法,并分析了各自的特点,重点对未来硬件木马检测技术研究进行了展望.

Hardware Trojan＇ s characteristics are small in size, easy to implement, and difficult to protect against, and they are currently one of the major security threats to Integrated Circuits. How to protect Integrated Circuits from the invasion of Hardware Trojan has increasingly become a problem to be solved urgently in various applications. In this paper, we analyze three security threats of Integrated Circuits, introduce the concept of Hardware Trojan, and discuss some of the more common classification of Hardware Trojans. On this basis, we focus on the Hardware Trojan protection methods, and analyze their characteristics from three aspects of Integrated Circuits, namely Test-time, Design-time, and Run-time. Finally, we propose the prospect of the future research about Hardware Trojan Protection.
