UWB on-chip fingerprinting and identification using carbon nanotubes

This paper presents new experimental investigations on a newly-proposed Ultra-Wideband (UWB) nanostructured identification and security technique. This technique is dedicated to securing electronic chips by using unique fingerprints created by electromagnetic waves interacting with nanostructured materials. The introduced work focuses on Carbon Nanotubes (CNTs) as a new candidate that is recently proposed by the authors. Physical robustness of this technique is meanwhile investigated with respect to aging effects, temperature variations and group delay measurements. The illustrated results proved the functionality of this new approach for hardware and chip security applications in the UWB range.
