Modern FPGAs offer various new features for enhanced re-configurability and better performance. One of such feature

is a dynamically Re-configurable 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 performance of the system. In

this paper, we study RLUT in the context of secure applications. Next, we design several case-studies to apply this feature on security critical scenarios. These case-studies vary

from destructive scenarios like stealthy hardware Trojans to

constructive scenarios like implementation of secret ciphers

with custom Sboxes and masking countermeasure.
