摘要
由于IC芯片生产和制造的分离,导致在IC芯片中容易被植入硬件木马等恶意电路。通过研究硬件木马的触发和行为机制,设计一种篡改内部信息的功能型硬件木马,以更好地说明硬件木马对IC芯片的危害。首先介绍了硬件木马的相关概念;然后以GPS主控模块为研究对象,提出了功能型硬件木马的设计思路和原理,分析了触发木马后对飞行器运动轨迹的影响;最后通过实验验证了验证了木马的有效性。
Caused by the separation of production and manufacturing of IC chips,hardware Trojans and others malicious circuit are easy to be implanted into the IC chip. By Through studying Trojan trigger and action mechanism,design a kind of hardware Trojans that can tamper with the internal information of functional, to illustrate the hardware Trojan harm to IC chips. First, this paper introduces the concepts of hardware Trojan;Master GPS control module as the research object,and puts forward the design thinking and principle of functional hardware Trojans, analyses the haedware Trojan that how to influence the vehicle trajectory;Finally, verifies the effectiveness of the hardware Trojan
