英文摘要： This project aims to investigate secure building technology of space information networks with fast self-organization, reconfiguration, especially the following key issues: high performance routing protocol in space information networks, key technology of distributed PKI, key exchange protocol, group key management scheme and access authentication technology. We used the dynamic routing technology with the capacity of self-adaptation and scalability based on node location information and the multi-path routing mechanism to design highly efficient dynamic routing protocols in space network. We also established trusted routing protocols in space information networks. In the basis of existing results of theoretical studies, we focused on the architecture and key technologies of public key infrastructure based on certificate and identity in the environment of space information networks with self-organization, reconfiguration. Secure and efficient group key management schemes have been established. By analyzing the respective application scenarios of existing formal proof method, we have proposed the formal method for security proof of group key management in space information networks with fast self-organization, reconfiguration. Through the studying of above key technologies, we have had some breakthrough in theory and methods of fast and secure building of space information networks and provided more complete and systematic theoretical support in design and implementation of space information networks.
