Dynamic Switched Quantum Key Distribution Networkwith PUF-based authentication
🤖 AI Summary
To address the vulnerability of link identity spoofing and the difficulty of achieving real-time dynamic authentication in quantum key distribution (QKD) networks, this paper proposes a centralized, dynamically reconfigurable QKD network architecture integrated with Physically Unclonable Functions (PUFs). Methodologically, we pioneer the embedding of PUFs at the QKD link layer to enable real-time, link-level identity authentication during quantum communication, while leveraging a centralized controller for dynamic routing of key distribution paths. Our contributions are threefold: (1) the first deep integration of hardware-rooted PUFs with dynamic QKD networking, overcoming limitations of conventional static authentication; (2) significantly enhanced resilience against spoofing and man-in-the-middle attacks in multi-user scenarios; and (3) experimental validation demonstrating stable secret key generation rates and controllable quantum bit error rates across all PUF-authenticated links, thereby concurrently improving both network security and operational flexibility.
