Satellite technologies represent, like other wireless technologies an, easy target for potential attacker. To protect against these threats, proper security technologies have to be applied. The objectives of this study are to determine how existing security technologies can be used for satellite networks, to assess their advantages and disadvantages, to consider the costs of these technologies and to recommend architectures for their deployment.
Furthermore emerging security technologies shall be analysed concerning their potential benefits for satellite networks. Finally a specification for a demonstrator shall be given, which is able to verify the suitability of the recommended security architectures for the scenario of business intranets connected by satellite networks.
One of the key issues is the influence of satellite network characteristics to existing and emerging security technologies. An example of these characteristics are the TCP accelerator technologies frequently used in satellite networks. These technologies often modify transport layer information, which is not accessible if certain security technologies are in place. A second example for these satellite characteristics is the possibility of an easy and efficient way to deploy IP Multicast, which restricts again the selection of adequate security technologies.
Another key issue is the benchmarking of new security technologies currently under development and their usability within satellite networks.
The following are the main benefits of this study:
The work undertaken for this project consisted of analysis and research only, and has not included development, simulation and experiments.
The project is complete.
