摘要
集成电路在各个领域都具有极其重要的作用,但是在当今集成电路设计、制造、测试、封装各种环节相分离的产业模式下,用户所使用的芯片可能会被别有用心者植入硬件特洛伊木马电路,这给信息安全领域带来了严重威胁,芯片级硬件木马的检测技术已经成为了芯片安全研究领域的新热点。首先介绍了硬件木马的概念、危害以及分类方式;然后对硬件木马检测技术国内外有影响的研究成果进行了详细的总结和评述,着重阐述了目前比较有效的旁路分析方法,指出基于功耗指纹分析的硬件木马检测技术是当前最有前途的一种检测方法;最后简要总结了硬件木马的主动防御机制。
The integrated circuit(IC)plays an important role in many fields,but the Hardware Trojan Horse(HTH)can be maliciously implanted into ICs by attackers because of separated IC design and fabrication mode.The existence of HTH threatens the information security.HTH detection begins to attract widely attention and comes into a new research field.Firstly,the concept of HTH,its hazards and its classification were described.Then some important researches on HTH detection approach were summarized.The researchers focus on side channel analysis detection,in which the power finger analysis techniques are the promising method to detect HTH.Finally,the proactive defense mechanisms of HTH were also summed up briefly.
