Location Assurance and Privacy in GNSS Navigation
Driving across unknown routes used to be stressful owing to the almost inevitable problem of getting lost. Thanks to Global Navigation Satellite Systems (GNSS) navigation devices, such problems are now in the past. These devices have revolutionized how we move: they guide us not only in unknown places but also within our own neighbourhoods. Our growing dependence on them to find our way is risky though: since the airwaves that carry GNSS signals are broadcast in the open air with a relatively weak strength, they are vulnerable to spoofing and meaconing attacks. Spoofing interferes with GNSS signals and misleads a driver into calculating a different location. Instead of interfering, a meaconing attack intercepts, alters or
