Researchers from the Department of Electrical Engineering at the University of Leuven in Belgium have developed a way of preventing distortions of positioning signals emitted by Galileo, the European equivalent of the US' GPS.
The development could have major implications for IoT, supply chain management, and other applications that really heavily on highly accurate device tracking.
At issue is how hackers can emit signals that override legitimate signals Galileo emits, which disrupt accurate satellite-positioning data.
The researchers have advised the European Commission on how to make Galileo signals harder to fake thanks to an authentication system they have developed. The system relies on electronic signatures, which are similar to those used for online banking, to ensure the signals received are accurate.
The system is expect to be completed by 2020, but will also require separate receivers to check electronic signatures, which are still in development.
