Consider the problem of mitigating impact on data integrity phasor measurement units (PMUs) given a GPS spoofing attack. We present sparse error correction framework to treat PMU measurements that are potentially corrupted due exploit nature attack, which is only small fraction PMUs affected by first attack identifiability conditions (in terms network topology, locations, and number spoofed PMU...

The growing dependence of critical civil infrastructure on global positioning system (GPS) makes GPS interference not only a safety threat, but also a matter of national security. The research done in this paper is initiated by the need to diminish this trouble on GPS based positioning. The suggested compensation technique assumes that the presence of a spoofing signal is immediately determined...

The performance of a spoofing detection and mitigation technique that makes use of the directions of arrival (DOAs) information about the navigation signals has been assessed. The directions of arrival have been estimated by utilizing a miniaturized antenna array developed for the reception of Galileo navigation signals of the public regulated service in E1 and E6 frequency bands. The performan...

To ensure a high security level in industrial systems over a period of time, maintenance is required. In this paper, we give an overview of security-related maintenance tasks incorporating new technologies employed in industrial control systems such as cloud computing but also new attack technologies such as GPS spoofing. We also provide a threat model that focuses on threats that materialize d...

Global navigation satellite system (GNSS) based is omnipresent in today's world, providing position, velocity, and time (PVT) information with inexpensive GPS receivers. These receivers are highly vulnerable to intentional interference like spoofing meaconing. The of a single receiver using spoofer setup widespread, the concept multiple targets distributed spoofers also equally adaptable. Tradi...

Spoofing sources can effectively disrupt a GPS receiver during the acquisition phase by generating multiple false correlation peaks and increasing the noise floor. Such deceptive correlation peaks can mislead the GPS receiver into acquiring the spoofer generated signals rather than the authentic signals. Also, the spoofer can increase the receiver noise floor to bury the authentic signals in th...
