Dynamic security-empowering architecture for space-ground integration information network

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protection technology) of space-ground integration information network (SGIIN), the existing security technologies were no longer applicable.Firstly, a security-empowering architecture for SGIIN was designed and formalized, which integrated capability orchestration unit of security service, analysis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.
