Enabling PUF-based Authentication in QKD Networks

Quantum key distribution (QKD) constitutes a paradigm shift in secure communications. As QKD moves from experimental to operational deployments in optical networks, the need for standardized, programmable, and vendor-neutral control frameworks becomes essential. This demo presents a modular and standards-compliant solution based on NETCONF/YANG framework aligned with ETSI standards, enabling dynamic configuration and monitoring of QKD nodes. A novel integration of physical unclonable functions is introduced, enabling node- level authentication required for quantum key exchange.
