确保电子元件不受硬件木马的侵害是一项非常艰巨的任务。研究表明，即使是最好的部署前和部署后检测机制也无法发现所有恶意包含，也无法阻止它们被激活。出于经济原因，不管是否存在此类木马，都要使用电子元件。我们开发了SAFER PATH架构，它使用指令和数据碎片、程序复制和投票来创建一个能够在活跃的硬件木马存在下安全运行的计算系统。我们保护计算的完整性，正在处理的数据的机密性，并确保系统的可用性。通过将小型可信计算基础与商用现成处理元素相结合，我们能够保护计算免受任意硬件木马的影响。
Ensuring electronic components are free from Hardware Trojans is a very difficult task. Research suggests that even the best pre- and post-deployment detection mechanisms will not discover all malicious inclusions, nor prevent them from being activated. For economic reasons electronic components are used regardless of the possible presence of such Trojans. We developed the SAFER PATH architecture, which uses instruction and data fragmentation, program replication, and voting to create a computational system that is able to operate safely in the presence of active Hardware Trojans. We protect the integrity of the computation, the confidentiality of data being processed and ensure system availability. By combining a small Trusted Computing Base with Commercial-Off-The-Shelf processing elements, we are able to protect computation from the effects of arbitrary Hardware Trojans.
