Silicon photonic physical unclonable function
Optics Express, 2017 Physical unclonable functions (PUFs) serve as a hardware source of private information that cannot be duplicated and have applications in hardware integrity and information security. Here we demonstrate a photonic PUF based on ultrafast nonlinear optical interactions in a chaotic silicon micro-cavity.

Self-Timed Physically Unclonable Functions
2012 5th International Conference on New Technologies, Mobility and Security (NTMS), 2012 Physically unclonable functions (PUFs) exploit the physical characteristics of silicon and provide an alternative to storing digital encryption keys in non-volatile memory. In this seminal work, I propose for the first time the use of self-timed logic to implement PUFs.
