摘要

Nanotechnology, when integrated with the Internet of Things (IoT), has led to the Internet of Nano Things (IoNT), revolutionizing sectors such as healthcare, industry, and defense. In healthcare, this evolution forms the Internet of Nano Medical Things (IoNMT), enabling real-time monitoring and treatment. However, the adaptability of 6G networks introduces vulnerabilities related to privacy, reliability, and secure data storage. To mitigate these challenges, this paper presents Q-BlockAuth, a blockchain-based authentication framework incorporating Quantum Key Distribution (QKD) to enhance data security in IoNMT networks. The framework employs decentralized peer-to-peer edge servers to ensure transparency, robustness, and minimal latency. Security validation using the Scyther tool and informal analysis confirms its resilience, while performance evaluation demonstrates superior efficiency and scalability compared to existing methods. Overall, Q-BlockAuth strengthens IoNMT communication by offering low latency, enhanced security, and resistance to cyber threats.
