Near-term quantum networks need to rely on control plane software to manage resource reservation for reliable end-to-end entangled link generation. While the quantum applications running on these networks are unconditionally secure, the operational robustness of Arqon, a centralized application enabling them, remains largely unexamined.

This work addresses the gap by performing a component-wise threat identification of Arqon, simulating attack vectors on its Python implementation, and providing concrete mitigation. The identified vulnerabilities can be primarily categorized into denial-of-service and data integrity attacks. This work also explores the impact of possible attack spillover between the classical control plane and the quantum data plane.

As the first formal security evaluation of Arqon, this thesis addresses its immediate vulnerabilities, establishes a clear road map for future control plane hardening, and helps in the transition of quantum network security from theory to practice. ...
