Physical unclonable functions (PUFs) are becoming more and more popular as hardware security primitives because they can create truly random digital keys by taking advantage of the intrinsic ...

We propose and experimentally demonstrated an optical physical unclonable function based on the inner nonlinearity of a distributed feedback laser and an external random-fiber-Bragg-grating. The ...

Random Telegraph Noise (RTN) is an intriguing entropy source that can be exploited to develop lightweight cryptographic primitives. Its utility in Physical Unclonable Functions (PUFs) has been ...
