Abstract:

To satisfy the above requirements that due to the dynamic characteristics (e.g., the dynamic variability of threats, and the dynamic changes of protection technology) of space-ground integration information network (SGIIN), the existing security technologies were no longer applicable.Firstly, a security-empowering architecture for SGIIN was designed and formalized, which integrated capability orchestration unit of security service, analysis unit of security situation and the response unit of security threat measure.Then, a double judgment method for the effectiveness of threat measure was proposed.Finally the method is theoretically proved to be credible by using belief mini-entropy.

Key words: space-ground integration information network, dynamic security empowering, security service orchestration, security threat measure, double judgement, security situation analysis
