Paper Abstract

In this paper, the state of the art of network protocols and security problems of space networks are firstly introduced. Then, it analyzes some security protocols that can be applicable to satellite networks. To validate the effect of security protocols in space networks, we use Stochastic Petri Nets (SPN) to model the communication process of Border Gateway Protocol - Satellite version (BGP-S). Furthermore, by comparison and analysis, the effect of three security protocols on average time delay is also analyzed from the SPN model with Stochastic Petri Net Package (SPNP) 6.0. What's more, the policies on choosing security shemes are discussed. Finally, a NS-2-based simulation for BGP-S is implemented and with the addition of security data flow test is made by comparison and analysis. Simulation results are basically in accordance with the numerical results of the SPN model.
