Abstract: The structure of spatial information networks was introduced in this paper, the characteristics and security threats were analyzed and the security goals were proposed. We applied the technology of hierarchical PKI to spatial information networks and constructed a model of multi-level CA.In this model, the security goals of confidentiality, authentication, integrity and non-repudiation were reached.
