Communication among Financial Institutions: What are the available answers to the quantum threat?
summary
Sets up cloud VPNs (Amazon VMs) across G7 capitals and proves intercontinental quantum-safe channels over IPSec IKEv2, testing three approaches: QKD impractical beyond ~100–200 km so discarded for this deployment, a distributed pre-shared randomness via security hubs (100 MB per participant, XOR-based key derivation, resilient to one compromised hub), and post-quantum KEMs (Kyber 768→1024) via key-management vendors (EvolutionQ, Quantum Exchange, Quantum Bridge). Demonstrates vendor interoperability at the KME level and manual cryptoagility by switching algorithms; results show feasible deployment but varying readiness and remaining standardization work.
