| Hardening Measures for Trusted-Node QKD Networks | QCRYPT 2026 | Mario Wenning, Tobias Fehenberger |
QKD networks rely on trusted nodes to overcome the limited reach of present-day QKD devices, weakening end-to-end security. We propose four complementary hardening measures, including secret sharing, PQC hybridization, path verification, and confidential computing, to reduce trust assumptions and enable more secure deployments in meshed QKD networks. |

| Quantifying the Impact of Systematic Deviations during Practical CV-QKD Receiver Calibration | QCRYPT 2024 | Tobias Fehenberger, Laurent Schmalen |
With state-of-the-art coherent detection techniques, the two-step CV-QKD receiver calibration introduces inevitable systematic deviations. In this work, we propose an empirical pre-calibration phase that allows to quantify the impact of these deviations on security. |
