Satellite Communication Security

Security Solutions for the ESA Ground Segment

Until now, none of the existing ESA spacecraft missions uses information security features to protect spacecraft commanding and telemetry. However, data security starts to play a very important role in order to counteract the more and more numerous security threads. Some of the upcoming ESA missions already have security requirements defined and proprietary security systems are being developed for these missions. As the need for security features in space missions is increasing, it is crucial that a generic approach is defined and possibly backed up by appropriate standardizations to reduce development and maintenance costs. The scope of this project is the definition of the required security features, a proposed approach for their integration into the existing standards and an analysis of the complications that come with them. This includes defining security layer locations in the space link communication protocol stacks and from this point identification of the ground segment infrastructure components that are needed to support them.
