Topology-Hiding Connectivity-Assurance for QKD Inter-Networking
Margherita Cozzolino, Stephan Krenn, Thomas Lorünser
While QKD ensures information-theoretic security at the link level, real-world deployments depend on trusted repeaters, creating potential vulnerabilities. In this paper, we thus i…

Topology-Hiding Path Validation for Large-Scale Quantum Key Distribution Networks
Stephan Krenn, Omid Mir, Thomas Lorünser +2
Secure long-distance communication in quantum key distribution (QKD) networks depends on trusted repeater nodes along the entire transmission path. Consequently, these nodes will b…
