Modeling and Simulation of the Invulnerability of Space Information Network

Aiming at the problem of the invulnerability of space information network, First, based on the composition and characteristic of space information network, a method of the invulnerability research of space information network which includes three research levels from microcosmic to macrocosmic is put forword, the cognition and psychology of human are introduced into the invulnerability research, and the invulnerability of space information network is modeled. Then the invulnerability of space information network is simulated and evaluated through the models. The method is effective for the invulnerability research of space information network, by the method the invulnerability of space information network can be simulated with multi-granularity mode which is qualitative and quantitative, macroscopical and microcosmic.
