Abstract

Low-altitude intelligent transportation (LAIT) relies on uncrewed aerial vehicles (UAVs) for diverse applications. However, current operational requirements often necessitate UAVs to broadcast their identity in plaintext, which introduces significant privacy risks. While anonymous credentials enable UAVs to prove legitimacy without revealing sensitive information or relying on constantly online central authorities, existing schemes lack integrated rate-limiting mechanisms essential for preventing denial-of-service attacks and managing high-density airspace resources safely. We propose RLAC, a rate-limiting anonymous credential scheme based on BBS

$^+$

signatures. RLAC ensures non-transferability by cryptographically binding credentials to secure hardware via Device Unique Keys (DUK). It enforces time-window-based verification limits to prevent abuse, incorporates conditional anonymity to trace only malicious UAVs while preserving compliant user privacy, and supports efficient credential revocation. We conduct a thorough analysis of RLAC’s security and demonstrate its practicality via comprehensive performance evaluations. Experimental results show that our scheme achieves computational overhead within tens of milliseconds in both credential issuance and presentation phases, with performance suitable for real-world UAV deployments.

RLAC：用于低空智能交通的限速匿名凭证

低空智能交通（LAIT）依赖于无人驾驶飞行器（uav）的多种应用。然而，目前的作战要求往往要求无人机以明文形式广播其身份，这带来了重大的隐私风险。虽然匿名凭证使无人机能够在不泄露敏感信息或依赖持续在线的中央当局的情况下证明合法性，但现有方案缺乏防止拒绝服务攻击和安全管理高密度空域资源所必需的集成速率限制机制。我们提出了一种基于BBS$^+$签名的限速匿名凭证方案RLAC。RLAC通过设备唯一密钥（DUK）将凭证加密绑定到安全硬件，从而确保不可转移性。它强制执行基于时间窗口的验证限制以防止滥用，结合条件匿名来仅跟踪恶意无人机，同时保持合规用户隐私，并支持有效的凭据撤销。我们对RLAC的安全性进行了深入的分析，并通过全面的性能评估来证明其实用性。实验结果表明，该方案在证书颁发和表示阶段的计算开销都在几十毫秒以内，性能适合实际的无人机部署。

期刊介绍： The proposed journal, called the IEEE Transactions on Network Science and Engineering (TNSE), is committed to timely publishing of peer-reviewed technical articles that deal with the theory and applications of network science and the interconnections among the elements in a system that form a network. In particular, the IEEE Transactions on Network Science and Engineering publishes articles on understanding, prediction, and control of structures and behaviors of networks at the fundamental level. The types of networks covered include physical or engineered networks, information networks, biological networks, semantic networks, economic networks, social networks, and ecological networks. Aimed at discovering common principles that govern network structures, network functionalities and behaviors of networks, the journal seeks articles on understanding, prediction, and control of structures and behaviors of networks. Another trans-disciplinary focus of the IEEE Transactions on Network Science and Engineering is the interactions between and co-evolution of different genres of networks.
