Human Indemnity Quantum Transmission FrameworkTM (HIQTFTM): A Defence-Grade Architecture for Long-Haul Quantum Key Distribution
Abstract
Dr. Nupur Mukherjee
A representative long-haul 1,000 km terrestrial quantum key distribution (QKD) deployment over commercial fibre infrastructure has demonstrated the feasibility of extended-range quantum-secure links. However, such systems rely on trusted-node repeaters and legacy optical transport equipment, creating exploitable attack surfaces for sophisticated adversaries. The Human Indemnity Quantum Transmission FrameworkTM (HIQTFTM) is the first comprehensive defence- grade architecture that simultaneously defeats honey traps, social engineering, NFC/EM side-channels, firmware backdoors, and trusted-node compromises while preserving 100% of the secret key rate. HIQTFTM migrates the baseline system to Twin-Field QKD (TF-QKD) with an orbital untrusted “Charlie” relay, augmented by PRF-deterministic basis selection and behavioural AI. This paper provides (1) detailed TF-QKD equations and 1,000 km-class deployment parameters, (2) adversarial threat analysis, (3) direct architecture comparison, (4) an orbital relay benchmark and deployment roadmap, and (5) a Standard Operating Procedure (SOP) for immediate integration. All claims are grounded in open-source, peer-reviewed literature. The framework is ready for licensing.
