A novel class of mono-stable static physically unclonable functions (PUFs) for secure key generation and chip identification is proposed. The fundamental concept is demonstrated through a 65 nm prototype that contains two different implementations, as well as several previously proposed PUFs to enable a fair comparison at iso-technology. From a statistical quality viewpoint, the achieved reproducibility and uniqueness are quantified by an intra-PUF Hamming distance (HD) lower than 1 and an… CONTINUE READING
