Chip-scale reconfigurable carbon nanotube physical unclonable functions.

ABSTRACT: With the rapid advancement of edge intelligence, ensuring the security of edge devices and protecting their communication has become critical. Physical unclonable functions, known as hardware fingerprints, are an emerging hardware security solution enabled with the physical variations inherent in the hardware systems. To facilitate a widespread edge deployment, here we present chip-scale reconfigurable physical unclonable functions built with carbon nanotube charge-trapping transistors, where the charge-trapping memory and physical variations of the transistors are harnessed to render over 10¹³ reconfigurable states and the demonstrated ideal physical unclonability. Arising from this, the physical unclonable functions prove robust resilience against advanced machine learning and
