Two researchers from the department of Electrical Engineering in the Faculty of Engineering at the Catholic University of Leuven (KUL) have developed a security system for the global navigation system. This relates to the European Union satellites.
These are known collectively as Galileo.
Galileo is a project which has long been developed by the European Space Agency (ESA) and the European GNSS Agency (GSA). It makes it possible to avoid pirates disturbing vehicle signals.
Using the Galileo system, a recipient can specify their position. However, this may be distorted if hackers send signals which perturb the system. The protection of these signals was one of the main objectives of the European Commission.
Together with the Commission, other European authority stakeholders wished to differentiate signals from other navigation systems, such as the American geolocation system – GPS.
With this new security system, authentication occurs by means of electronic signature, whilst verification happens through the TESLA method (a means of transmitting electronic energy through space).
