Abstract
This special session paper discusses recent advances on photonic physical unclonable functions (PUFs), providing a broader overview of and motivation for photonic PUFs. We discuss their potential advantages, such as a higher entropy, larger complexity, and possibly better resilience against machine learning attacks. We also deal with some recent implementations based on linear and non-linear optics, alongside with their main advantages and limitations.
