ABSTRACT
Satellites are expected to play an increasingly important role in providing broadband Internet services over long distances in an efficient manner. Most future networks will be hybrid in nature — having terrestrial nodes interconnected by satellite links. Security is an imporSSSL tant concern in such networks, since the session 2 Proxy satellite segment is susceptible to a host of attacks, including eavesdropping, session hijacking and data corruption. In this article we address the issue of securing communication in satellite networks. We discuss various security attacks that are possible in hybrid SSSL session 1 SSSL handshaking and satellite translation at client proxy (RPA) networks, and survey the different solutions proposed to secure data communications in these networks. We look at the perforMost future networks mance problems arising in hybrid networks due to security additions like Internet Security Prowill be hybrid in tocol (IPSec) or Secure Socket Layer (SSL), and suggest solutions to performance-related nature — having problems. We also point out important drawbacks in the proposed solutions, and suggest a terrestrial nodes hierarchical key-management approach for interconnected by adding data security to group communication in hybrid networks.
