Kaiyu Liu, Hanwen Luo, Lei Deng, Qi Yang, Deming Liu, Zhijun Yan, Mengfan Chen · 2023
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 reliability and randomness are verified.
