Abstract:

The characteristics of space-ground network was combed.Against security threats in space-ground network,the security risks faced by measurement control,operation control,terminal access,wireless transmission,transmission,business information system,maintenance management were analyzed.Further,by dividing space-ground network security into four layers:foundation layer,access layer,network layer and application layer,a security architecture to protect space-ground network was proposed.An implement mechanism (including unifi ed security management and security situation aware,entity authentication and access protection,interconnection control,cipher on-demand service,dynamic reconstruction of security service ) was designed to guarantee the security of space-ground network.

Key words: space-ground network security guarantee, security situation aware, entity authentication and access protection, interconnection control, cipher on-demand service, dynamic reconstruction of security service
