The Global Positioning System (GPS) signals are very weak signal over wireless channels, so they are vulnerable to in-band interferences. Therefore, even a low-power interference can easily spoof GPS receivers. Among the variety of GPS signal interference, spoofing is considered as the most dangerous intentional interference. The spoofing effects can mitigate with an appropriate strategy in the...

Spoofing could pose a major threat to Global Positioning System (GPS) navigation, so the GPS users have to gain an in-depth understanding of GPS spoofing. Since spoofing attack can influence position results, spoof compensation is possible through reducing position deviations. In this paper, a novel processing technique is proposed and the wavelet transform is used to eliminate the impact of sp...

GPS spoofing has become a hot topic. At the 2011 Institute of Navigation (ION) GNSS conference, 18 papers discussed spoofing, compared with the same number over the past decade. ION-GNSS also featured its first panel session on anti-spoofing, called “Improving Security of GNSS Receivers,” which offered six security experts a forum to debate the most promising anti-spoofing technologies. The spo...

In some recent articles, the spoofing of Phasor measurement unit (PMU) GPS receiver has been highlighted as a threat to power grid protection system. Having spoofed PMU GPS signals, one can manipulate the measurements and inject bad data to power grid protection system. The previous anti spoofing methods are all based on GPS signal analysis. The mentioned methods are just able to detect spoofin...

Global Positioning System (GPS) is used ubiquitously in a wide variety of applications ranging from navigation and tracking to modern smart grids and communication networks. However, it has been demonstrated that modern GPS receivers are vulnerable to signal spoofing attacks. For example, today it is possible to change the course of a ship or force a drone to land in an hostile area by simply s...

Phasor measurement unit (PMU) GPS receiver spoofing has been addressed in the recent literatures. Having spoofed GPS signals, the spoofer can inject bad data into power system control center and consequently the protection system will face serious problems. The existing anti spoofing techniques are all based on GPS signal analysis and are just able to detect spoofing. However, as PMUs are place...

The recent FCC ruling has proposed 3.5 GHz database-driven cognitive radio networks (CRNs) in which the database relies on a base station to determine his location to query the database for available spectrum. However, this creates a critical loophole for mounting GPS-spoofing attack, which can potentially result in interference with critical incumbent users. The adversary attacks base stations...

Results from Global Positioning System (GPS) spoofing tests against Phasor Measurement Units (PMUs) are presented, demonstrating that PMUs are vulnerable to spoofing attacks. A GPS spoofer can manipulate PMU time stamps by injecting a counterfeit ensemble of GPS signals into the antenna of the PMU’s time reference receiver. A spoofer-induced timing error of only a few tens of microseconds cause...

The aviation industry’s increasing reliance on GPS to facilitate navigation and air traffic monitoring opens new attack vectors with the purpose of hijacking UAVs or interfering with air safety. We propose Crowd-GPS-Sec to detect and localize GPS spoofing attacks on moving airborne targets such as UAVs or commercial airliners. Unlike previous attempts to secure GPS, Crowd-GPS-Sec neither requir...
