A Perspective on Security and Trust Requirements for the Future

As integrated circuit manufacturing becomes increasingly global and the availability of domestically produced advanced transistor nodes shrinks, security vulnerabilities within the supply chain become a significant issue for IC defense applications. In this talk, we will present some of DARPA's efforts towards creating an active community and tool library for circuit design obfuscation in an effort to achieve trusted-by-design IC manufacturing at international foundries. By using a combination of techniques, our goal is to make the placement and triggering of hardware Trojans more difficult and their detection easier, and to make reverse engineering intractable within the window of vulnerability. We will discuss the development of obfuscation assessment metrics and trade-offs in power, area, and timing overhead, and the creation of an obfuscation technique library to help identify optimal obfuscation strategies in future IC design.
