Abstract
We present a silicon-based Chaotic-Cavity Optical Physically Unclonable Function(CCO-PUF) embedded inside smart-sensor based devices utilizing nonlinear-optical properties of bi-axial crystals present inside a chaotic cavity. The photonic circuit produces statistically diverse yet reproducible multimodal photonic outputs that provides a large statistical degree of freedom for generating randomness in the device responses upon electrical as well as photonic triggering that can be employed for producing authentication keys for users seeking on-demand access to IoT devices . Such PUFs can be very robust against side-channel attacks and machine-learning attacks for their wide operability range, complex nano-photonic operation and strong degree of pseudo-randomness.
