Abstract

Quantum Key Distribution (QKD) protocols, particularly the decoy-state BB84, offer a promising approach to enhancing network security by enabling theoretically unbreakable encryption. Integrating QKD into OpenDaylight Software-Defined Networking (SDN) controllers addresses key management challenges in dynamic, large-scale networks. Automated key rotation for IPSec and VPN tunnels eliminates the need for manual key distribution, ensuring continuous encryption with minimal latency. The implementation of ETSI-compliant QKD protocols ensures efficient, seamless key rotation without compromising performance. Furthermore, Quantum Bit Error Rate (QBER) thresholds are optimized to enhance key generation rates while minimizing key discards. Simulation results indicate that this solution significantly improves network security, reduces latency, and maintains continuous encryption. This research explores how integrating automated QKD protocols within SDN-driven networks can provide a practical and scalable solution for safeguarding communications, ultimately strengthening defenses against cyber threats while maintaining high network performance.
