CEF: Connecting Elaborate Federal QKD Networks

TL;DR

This paper proposes a four-step orchestration framework to enable the integration of complex, autonomous quantum key distribution networks developed by different actors into a federated system.

Contribution

It introduces a novel 4-step framework for connecting and managing elaborate federated QKD networks with high autonomy.

Findings

Framework addresses key challenges in federated QKD network integration

Optimizes QKD design for complex, multi-actor networks

Provides protocol enforcement mechanisms for secure federation

Abstract

As QKD infrastructure becomes increasingly complex while being developed by different actors (typically national governments), interconnecting them into a federated network of very elaborate sub-networks that maintain a high degree of autonomy will pose unique challenges. We identify several such challenges and propose a 4-step orchestration framework to address them based on centralized research, target network planning, optimal QKD design, and protocol enforcement.
