摘　　要：为了使一组卫星动态配置成一个具有灵活的分布式体系结构的集成网络信息系统,可以采用adhoc组网方式,这种卫星网络的组网方式带来了新的安全挑战。提出了一个灵活的安全方案,设计了公钥基础设施和认证策略。基于完全分布式的认证中心,可以直接采用几乎所有的标准公钥认证协议。当空间节点的计算能力有限时,设计了一个轻型的基于对称密钥算法和单向散列函数的认证协议,在提供保密性和数据完整性的同时大大减小了计算量。To be implemented using a flexible distributed architecture consisting of a constellation of dynamically deployed or configured satellites that were networked together into an integrated information system, the satellites could form an ad hoc self-organizational network, which posed unique challenges to security for the network. A novel and flexible security architecture was proposed, which aimed to provide public key infrastructure and authentication scheme. Based on the absolute distributed certificate authority almost any standard public-key-based authentication protocol could be adopted directly, In cases where the space nodes involved were extremely limited in computational resources, a lightweight authentication scheme that provided integrity and confidentiality based on cryptographic hash functions and symmetric key cryptography was proposed.
