Study on Structural Expansion of Quantum Cryptographic Communication (QKD) — Organization of Technical Possibilities and Patentability Perspectives Based on the Five TRIZ Viewpoints of "Substitution, Reversal, Parallelism, Staging, and Analogy" —
Abstract
This paper examines structural expansion paths for Quantum Key Distribution (QKD) using five TRIZ viewpoints: substitution, reversal, parallelism, staging, and analogy. It explores hybrid QKD-PQC architectures, terrestrial-satellite integration, cost reduction, and deployment strategy, while adding simple formulas and numerical examples to support technical and patent-oriented evaluation.
