Abstract :
Compared with the original system that has unidirectional broadcasting characteristics, the interactive satellite remote education system which based on DTN greatly improved. However, in the special application environment of the satellite remote education system, the traditional Internet security mechanism can´t meet the DTN security needs. In order to ensure the reliability and safety of the information which from terminal users to satellite broadcast center in the remote education system, the paper proposes a kind of authentication and communication security mechanism that makes full use of the functions of the conditional Access Module (CAM) which exist in the original satellite remote education system and when authenticating the nodes of the system, we use the symmetrical encryption and asymmetric encryption fusion scheme. Analysis showed that the mechanism is safe, reliable, strong compatibility, economic and applicable.
