Cluster-based Method for Eavesdropping Identification and Localization in Optical Links

, 2023
We propose a cluster-based method to detect and locate eavesdropping events in optical line systems characterized by small power losses. Our findings indicate that detecting such subtle losses from eavesdropping can be accomplished solely through optical
