Defending Against GPS Spoofing by Analyzing Visual Cues
Massive GPS navigation services are used by billions of people in their daily lives. GPS spoofing is quite a challenging problem nowadays. Existing Anti-GPS spoofing systems primarily focus on expensive equipment and complicated algorithms, which are not practical and deployable for most of the …

GPS spoofing detection for the power grid network via a multi-receiver hierarchical architecture
… network using the Global Positioning System (GPS) as a common timing reference. GPS serves as an excellent timing source due to its global coverage as well as its precise, sub-microsecond level timing accuracy. However, because civilian GPS signals are unencrypted with a publicly available …

Real-Time Detection of GPS Spoofing Attack with Hankel Matrix and Unwrapped Phase Angle Data
… data has become a widely explored area. However, GPS-spoofing and FDIA attacks require different responsive actions. State-estimation based attack detection method works similar way for both types of attacks. It implies that using state-estimation based detection alone doesn’t give the control …

Spoofing GPS receiver clock offset of phasor measurement units
We demonstrate the feasibility of a spoofing attack on the GPS receiver of a phasor measurement unit (PMU). We formulate the attack as an optimization problem where the objective is to maximize the difference between the time offset of the PMU's receiver clock before and after the attack. Since the …
