Such measurements also could enable effective realtime system monitoring and control, which are considered to be the key to preventing wide-sc...

The Global Positioning System (GPS) is vulnerable to various deliberate and unintentional interferences. Therefore, identifying and coping with various interferences in this system is essential. This paper analyzes a method of reducing the dimensions of Cross Ambiguity Function (CAF) images in improving the identification of spoofing interference at the GPS using Multi-Layer Perceptron Neural N...

We propose a simple low-cost technique that enables civil Global Positioning System (GPS) receivers and other civil global navigation satellite system (GNSS) receivers to reliably detect carry-off spoofing and jamming. The technique, which we call the Power-Distortion detector, classifies received signals as interference-free, multipath-afflicted, spoofed, or jammed according to observations of...

Flying Ad-Hoc Networks (FANETs) are groups of UAVs connected in an manner to accomplish a common mission. The widespread acceptance due their low cost and high efficiency has attracted malicious security attacks against them. These cannot be easily prevented UAVs’ limited computational power, short battery life, inability execute complex algorithms. FANETs rely on the Global Positioning System ...

In order to obtain higher detection probability of the GPS spoofing, a general identification scheme with decision fusion is proposed. Firstly, the singular values of the wavelet transformation coefficients of both spoofing and genuine signal are computed and formed as the feature vectors. Then, the feature vectors are input into three classifiers, which are the support vector machines (SVM), t...

Many power grid applications rely on the time synchronized measurement data collected by phasor units (PMUs) and or Merging Units (MUs)). The synchronization of from multiple PMUs MUs relies global positioning system (GPS) to provide reference. civilian GPS receivers used in PMU operate according publicly available mechanism. Therefore, attackers can easily generate false signals with low-cost ...

Reliable and precise electrical wave measurements are essential to the stability and efficiency of a power system. Phasor Measurement Units (PMUs), also known as synchrophasors, are devices that provide precise synchronized voltage magnitude and phase measurements at a high sampling frequency. Widely regarded as one of the most vital devices in monitoring and control for the future of power sys...
