Abstract:

By decoupling the control plane and the data plane, software defined satellite networks achieves a unified network management, which is a new type of satellite network architecture. Security authentication is a core problem in software defined satellite networks. The control path between the control plane and the data plane has the characteristic of periodic switching, which makes the network face significant security threats. However, there are few studies on software defined satellite network security now around the world. This paper proposes a lightweight fast security authentication strategy that reduces the time overhead of frequent handover under proven security. Experimental results in the simulation experiment platform show that the computational cost of the strategy is large, but the strategy saves communication time, which is suitable for software defined satellite networks.

Key words: software defined satellite networks, lightweight, fast security authentication
