Abstract:Modern FPGAs offer various new features for enhanced reconfigurability and better performance. One of such feature is a dynamically Reconfigurable LUT (RLUT) whose content can be updated internally, even during run-time. There are many scenarios like pattern matching where this feature has been shown to enhance the performance of the system. In this paper, we study RLUT in the context of secure applications. We describe the basic functionality of RLUT and discuss its potential applications for security. Next, we design several case-studies to exploit RLUT feature in security critical scenarios. The exploitation are studied from a perspective of a designer (e.g. designing countermeasures) as well as a hacker (inserting hardware Trojans).
