Authentication and Access Control in Satellite Network

It is obvious that satellite networks are of usefulness in the area of information technology, and can be utilized to the extent of extending the application of information technologies further. Because of the high variability and complexity of satellite network, the problems of network security in satellite network must be solved. The unique attributes of satellite network that is different from those of the ground network is introduced first, then the authentication and access control models selected based on the attributes of satellite network are discussed. The analysis of satellite network security is performed by means of simulation, and it comes to the conclusion based on the simulation results.
