摘　　要：考察了由卫星和接入节点所构成的分层式空间信息网模型,首次提出了一种适用于该网络模型的基于证书的公钥基础设施。该模型中作为核心网络的卫星层采用分布式CA管理证书,而其他节点作为接入节点,其证书管理采用集中式CA。该模型具有很强的可扩展性和一定的安全性,适用于空间信息网复杂而多变的环境。With the development of space communication technologies, security issues in space information networks become increasingly important. However, there has been no good solution to this problem in satellite networks. This paper investigates the layered model of space information networks, which consist infrastructure suitable for of satellites and access nodes; and proposes a certificate-based public key the this model. In this model, the Certificate Management of satellite layer uses distributed CA, and the Certificate Management of other nodes （as access nodes） uses centralized CA. The proposed mode is highly scalable and has a certain degree of safety. So it is applicable to the complex and changeable environment in space information networks.
