چکیده
A malicious attacker could, by taking control of internet-of-things devices, use them to capture received signal strength (RSS) measurements and perform surveillance on a person's vital signs, activities, sound in their environment. This article considers an who looks for subtle changes the RSS order eavesdrop vibrations. The challenge adversary is that vibrations cause very low amplitude RSS, typically quantized with significantly larger step size. contributes lower bound attacker's monitoring performance as function size sampling frequency so designer can understand relationship. Our little-known counter-intuitive fact improve sinusoidal parameter estimates making some devices transmit add interference power into measurements. We demonstrate this capability experimentally. As we show, typical transceivers, monitor remarkable accuracy. New mitigation strategies will be required prevent attacks.

متن کاملAdaptive Signal Detection in Auto-Regressive Interference with Gaussian Spectrum
A detector for the case of a radar target with known Doppler and unknown complex amplitude in complex Gaussian noise with unknown parameters has been derived. The detector assumes that the noise is an Auto-Regressive (AR) process with Gaussian autocorrelation function which is a suitable model for ground clutter in most scenarios involving airborne radars. The detector estimates the unknown...
متن کاملEstimation of harmonic interference parameters of surface-NMR signal using an adaptive method and residual signal power
Surface nuclear magnetic resonance (surface-NMR) method is a well-known tool for determining the water-bearing layers and subsurface resistivity structure. Harmonic interference is an inevitable interference in surface-NMR measurements. Accurate estimation of harmonic interference parameters (i.e., fundamental frequency, phase and amplitude) leads to better retrieval of power-line harmonics and...
