The HROS dataset consists of OPT and SAR images collected from multiple sources. The OPT images are collected from the large-scale public remote sensing datasets. Image sources include different platforms, including Google Maps, JL-1 satellite, Gaofen-2 satellite, aerial imagery, etc. The SAR images are captured by the AS-01 satellite, developed by Skysight Technology Co., LTD. The AS-01 satellite is equipped with a two-dimensional scanning plane solid-state active phased array synthetic aperture radar (SAR) payload, which enables high-resolution imaging capabilities.

This letter presents a novel approach to bolster the physical layer security of optical communication systems, specifically within Passive Optical Networks (PONs), through the utilization of device fingerprints. In this proposed scheme, we employ Optical On-Off Keying (OOK) modulation for signal transmission and subsequently extract distinct fingerprint features from the eye diagrams of these OOK signals. These fingerprint features are then subjected to dimensionality reduction via Siamese neural networks.
