Abstract: In space information networks (SIN), to continuously collect information and enlarge the observation range, the group aircrafts need to fast access authenticate with the satellite. Unfortunately, the existing authentications schemes cannot be applied in SIN due to its particular characteristics, such as high dynamic topology, satellite computation and limited communication resources, etc. To this end, we propose a PCL (protocol composition logic) secure and efficient group authentication protocol named as TSNP through utilizing symmetric encryption and key hierarchy. With it, the authenticated node enables other users in this group to gain the session key and realize the secure group authentication and handover. Furthermore, we analyze its security properties in PCL mode and prove its composition security based on parallel and sequential rules. As a further contribution, the experimental results indicate that TSNP can reduce not only the dependence on group management center but also the satellite’s computation and communication overhead.
