Neuron-PUF: Physical Unclonable Function Based on a Single Spiking Neuron
2021 IEEE 27th International Symposium on On-Line Testing and Robust System Design (IOLTS), 2021 We propose a novel Physical Unclonable Function (PUF) concept based on a single spiking neuron. The inherent variability of the neuron results in a chip-unique analog spiking pattern that is digitized to produce a chip-unique digital key. A stability booster is also employed based on self-masking to obtain a fully stable digital key.
