(2022) Eavesdropping against bidirectional physical layer secret key generation in fiber communications. In: 2022 IEEE Photonics Conference (IPC), 13-17 November 2022, Vancouver, BC, Canada978-1-6654-3488-12374-0140https://doi.org/10.1109/IPC53466.2022.9975754https://dspace.lib.cranfield.ac.uk/handle/1826/18962Physical layer secret key exploits the random but reciprocal channel features between legitimate users to encrypt their data against fiber-tapping. We propose a novel tapping-based eavesdropper scheme, leveraging its tapped signals from legitimate users to reconstruct their common features and the secret key.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/eavesdroppingtwo-way secret key generationphysical layer securityfiber communicationsConference paper978-1-6654-3487-4
