摘要

It is estimated that the global count of 6 G devices will soar to 121 billion by 2040. Despite this growth, the cybersecurity infrastructure of 6 G networks largely mirrors that of its predecessors, introducing a spectrum of vulnerabilities. To mitigate these risks, dynamic address technology has been adopted. However, the implementation of dynamic address technology encounters specific hurdles, particularly in efficiently locating dynamic random addresses. Therefore, this paper introduces a novel approach by integrating a Domain Name System (DNS) specifically tailored for dynamic address resolution within the Consumer Internet of Things (CIoT). Our methodology encompasses several key innovations: firstly, we propose an identity authentication strategy that leverages DNS queries, enabling seamless CIoT device authentication without necessitating alterations to existing frameworks. Secondly, we introduce a method for randomizing DNS record storage, complemented by an expiration mechanism, to significantly enhance the performance of DNS record updates. Thirdly, we implement a time-based Least Recently Used (LRU) cache mechanism to substantially improve DNS resolution efficiency. Our empirical findings underscore the efficacy of the proposed DNS system in facilitating CIoT dynamic address protection, demonstrating its user-friendliness and its capability to meet performance benchmarks. Notably, the DNS record update process is expedited, achieving speeds up to 805 times faster than those observed in traditional Windows Server DNS.
