  2. Radio jamming - Wikipedia

    en.wikipedia.org/wiki/Radio_jamming

    Simple continuous transmission on a given channel will continuously stop a transmitter transmitting, hence jamming the receiver from ever hearing from its intended transmitter. Other jammers work by analysing the packet headers and, depending on the source or destination, selectively transmitting over the end of the message, corrupting the packet.

  3. Electromagnetic shielding - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_shielding

    Electromagnetic shielding that blocks radio frequency (RF) electromagnetic radiation is also known as RF shielding. EMF shielding serves to minimize electromagnetic interference . The shielding can reduce the coupling of radio waves, electromagnetic fields, and electrostatic fields .

  4. Van Eck phreaking - Wikipedia

    en.wikipedia.org/wiki/Van_Eck_phreaking

    The oscillation of these electric currents create electromagnetic radiation in the RF range. These radio emissions are correlated to the video image being displayed, so, in theory, they can be used to recover the displayed image. In a CRT, the image is generated by an electron beam that sweeps back and forth across the screen.

  5. Electronic harassment - Wikipedia

    en.wikipedia.org/wiki/Electronic_harassment

    Electronic harassment, electromagnetic torture, or psychotronic torture is the delusional belief, held by individuals who call themselves "targeted individuals" (TIs), that malicious actors are transmitting sounds and thoughts into people's heads, affecting their bodies, and harassing them generally.

  6. Faraday cage - Wikipedia

    en.wikipedia.org/wiki/Faraday_cage

    This prevents external RF (radio frequency) signals from being added to data collected from the patient, which would affect the resulting image. Technologists are trained to identify the characteristic artifacts created on images should the Faraday cage be damaged, such as during a thunderstorm.

  7. Radar jamming and deception - Wikipedia

    en.wikipedia.org/wiki/Radar_jamming_and_deception

    The missile utilizes passive RF homing which reduces its probability of detection. A countermeasure to ARM is not to use self-protective jamming (one could use stand-off jamming, assuming that the missiles has a range no longer than the radar), or have a decoy taking the missile (such as ADM-160 MALD and AN/ALE-55 Fiber-Optic Towed Decoy ).

  8. Wireless identity theft - Wikipedia

    en.wikipedia.org/wiki/Wireless_identity_theft

    Wireless identity theft is a relatively new technique for gathering individuals' personal information from RF-enabled cards carried on a person in their access control, credit, debit, or government issued identification cards. [6] Each of these cards carry a radio frequency identification chip which responds to certain radio frequencies.

  9. Electromagnetic attack - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_attack

    In cryptography, electromagnetic attacks are side-channel attacks performed by measuring the electromagnetic radiation emitted from a device and performing signal analysis on it. These attacks are a more specific type of what is sometimes referred to as Van Eck phreaking , with the intention to capture encryption keys.
