摘　　要：相较于传统地面网络,开放性更强的空天信息网络存在卫星节点接入认证与密钥更新难等安全问题。针对以上问题,着重研究了导航卫星系统中网络节点的接入互信认证机制,并提出了一种基于分簇空天信息网络的轻量级接入认证方案。安全分析显示,所提方案能够有效抵御空天信息网络中身份假冒、消息重放、中间人攻击等多种典型安全威胁。实验结果表明,卫星节点在接入认证过程中所需计算开销更少,能够实现导航卫星系统在资源受限条件下的安全组网认证。Compared to traditional ground networks, the aerospace information network with more openness is faced with safety issues such as satellite node access authentication and re-keying difficulties. Aiming at these issues, the mutual trust access authentication mechanism of network nodes in navigation satellite systems was mainly investigated in this paper, and a lightweight access authentication scheme was proposed based on the clustering aerospace information network. As shown in security analysis, the proposed scheme was able to defend against multiple security threats in the aerospace information network, including identity theft, message replay, and man-in-the-middle attacks. The experimental results demonstrated that the computational cost in the process of access authentication was lower for satellite nodes, enabling secure networking and authentication of navigation satellite systems even under resource-constrained conditions.
