Placement-Specific Sufficient QKD Block Sizes for Hybrid QKD–ML-KEM Systems: Finite-Key Planning and Split-Security Provisioning
Hybrid quantum key distribution (QKD) and post-quantum cryptography (PQC) systems are often described as layered security architectures, yet deployments face a basic provisioning question: how many QKD bits are needed, and where should they enter an ML-KEM-based system? This article develops a placement-aware framework...
