  Abstract

This paper proposes an HTUR-based QKD operational framework for efficient and secure quantum key distribution networks (QKDN) in heterogeneous military communication environments comprising wired, wireless, and satellite links. Trusted-node (TN) QKD is applied to physically protected wired segments, while measurement-device-independent (MDI) QKD is deployed in high-risk wireless and satellite segments to enable segment-oriented operation. An AI-SDN-based control scenario dynamically switches between TN and MDI modes based on real-time link quality and security status. The proposed framework balances security and transmission efficiency, enhances network resilience through flexible routing and rapid bypass, and provides operational guidelines for sustainable QKD in multi-domain environments.
