摘要
随着无线通信技术的日益发展,无人机自组网在救援、巡逻和侦查等领域都得到了广泛运用。然而,由于无人机自组网网络结构灵活多变且缺乏基础设施的支持,该网络面临严重的身份安全威胁。尽管当前存在各种无第三方安全方案,但这些方案存在性能低下和安全性不足等问题,难以在无人机自组网上部署。针对这些问题,该文提出一种基于IBE的认证方案,将实体身份信息作为公钥,实体无需存储额外的公钥信息,降低了密钥存储开销。同时,该方案支持批量认证,极大地提升了认证效率。此外,通过引入哈希链技术,有效地保留和复用无人机首次认证后的状态信息,降低了后续无人机的认证成本。通过形式化的安全分析,证明该方法能抵御身份伪造、中间人等恶意攻击。相较于已有方案,该方案的计算和存储开销更低。
With the continuous advancement of wireless communication technology,the application of unmanned aerial vehicle(UAV)ad-hoc networks in areas such as rescue,patrol,and reconnaissance has become widespread.However,due to the flexible and dynamic nature of the network structure and the lack of infrastructure support,UAV ad-hoc networks face significant identity security threats.Despite the existence of various third-party security solutions,the current approaches suffer from issues such as low performance and insufficient security,making them challenging to deploy effectively in UAV ad-hoc networks.To address these challenges,we propose an authentication scheme based on Identity-Based Encryption(IBE),which utilizes entity identity information as public keys.This approach eliminates the need to store additional public key information,thereby reducing key storage overhead.Additionally,the proposed scheme supports batch authentication,significantly enhancing the efficiency of the authentication process.Furthermore,by introducing hash chain technology,we effectively retain and reuse the state information obtained after the initial UAV authentication,thereby reducing the authentication costs for subsequent UAVs.Through formal security analysis,the proposed method is demonstrated to resist malicious attacks such as identity forgery and man-in-the-middle attacks.In comparison to existing solutions,the computational and storage overhead of the proposed scheme is lower.
