Sentinel-Based Failover for QKD-Augmented IPsec Tunnels
Sentinel-based failover mechanism maintains IPsec tunnel availability when QKD infrastructure fails, solving a practical resilience gap in hybrid quantum-safe deployments.

arXiv:2609.01121v1 Announce Type: cross Abstract: Quantum-safe IPsec through hybrid key establishment is practical, but creates a critical operational challenge: how to maintain tunnel availability when the QKD infrastructure becomes unavailable. In this paper, we present the design, implementation, and experimental evaluation of a quantum-safe key establishment mechanism for an IPsec tunnel that combines X25519, ML-KEM, and ETSI GS QKD 014 keys through the RFC 9370 multiple key exchange mechan
Editorial Analysis
European enterprises piloting quantum-safe networking need failover mechanisms that preserve tunnel availability without silently downgrading cryptographic assurance.
Include QKD failover requirements in your quantum-safe networking roadmap to avoid availability blind spots.
