Anonymous Cross-domain Authentication and Key Agreement Scheme for UAV
X. Sean Wang, Wei Wang, Yiliang Liu, Ping Cao · 2024
With the development of low-altitude network, cross-domain collaboration between unmanned aerial vehicle (UAV) and ground station is becoming increasingly important. To ensure the legitimacy of identity, it is imperative to design a cross-domain authentication scheme. However, current cross-domain authentication schemes still face challenges such as low computational efficiency and high storage overhead, and still have some security vulnerabilities. This paper proposes a cross-domain authentication and key agreement scheme for UAVs, which primarily employs a combination of symmetric encryption and hash functions. By holding cross-domain tokens, UAVs can directly engage in cross-domain authentication, ultimately achieving key agreement with ground station. We conduct security and performance analyses, demonstrating the feasibility of our scheme in resource-constrained low-altitude network.
