Adaptive Resource Allocation in Quantum Key Distribution (QKD) for Federated Learning. (arXiv:2208.11270v2 [cs.CR] UPDATED)

Increasing privacy and security concerns in intelligence-native 6G networks
require quantum key distribution-secured federated learning (QKD-FL), in which
data owners connected via quantum channels can train an FL global model
collaboratively without exposing their local datasets. To facilitate QKD-FL,
the architectural design and routing management framework are essential.
However, effective implementation is still lacking. To this end, we propose a
hierarchical architecture for QKD-FL systems in which QKD resources (i.e.,
wavelengths) and routing are jointly optimized for FL applications. In …
