A unique unclonable chip ID has been implemented using various platforms in the
recent years. In this paper, we investigate the use of polymorphic gates as a new
mechanism for implementing a unique chip ID in systems already containing some
polymorphic gates. The proposed solution exploits the fact that switching time of
polymorphic gates (controlled by Vdd) is slightly different even for neighboring
gates on the same die because of fabrication variations. We applied a partial
reconfiguration in order to generate 48-bit IDs on the reconfigurable polymorphic
REPOMO32 chip that we have developed in our previous research. We achieved 94.44%
stable bits which is reasonably close to existing approaches.
