Surround noise - noise in broadband electromagnetic radiation TEMPEST LGS503/449 protective systems 0.01 MHz - 2000 MHz

Noise generator. The operation of various devices (such as computers, recording technologies) may include signal generation (TEMPEST) containing classified or confidential information.

These signals can be intercepted using special equipment (USRP, spectral evaluators).  

Based on these news leaks was developed by Russian companies Generator of radio broadband electromagnetic noise, radiation which are designed to operate in a protected room and active protection of information systems (APS ). Providing protection against leaks through TEMPEST channels by stopping the boundary of the broadband electromagnetic noise control area that can be spurned or secured to the wiretap.

Noise - noise generator for powering circuits, underground power lines and backup sources in the band 0.01 MHz - 2000 MHz.

The 230V electrical noise generator of 230V mains lines is designed to actively protect the object from information leakage via the 230V supply network ("Phase, phase conductor", "zero" and "protective conductor"), and means against unauthorized theft of information through unwanted phosph spectrum leaks through the creation of broadband noise transmission in the frequency range 0,01 MHz to 2000 MHz.

The device can be used to protect objects and ESA installed in selected areas in category 1, inclusive.

The device is an analog and digital average power generator that is introduced into the antenna and power supply network. The device is powered by an alternating voltage of 230 V and a frequency of 50 Hz.

Enable / disable noise generation –noise is performed by a button on the "network" on the back panel of the device.

On the front panel, the indicator light indicates operation.

On the back panel of the generator there is a connector for wired remote control (batteries not included).

TEMPEST protective systems

Operation of various devices (for example, computers) may involve generation of signals (TEMPEST) that contain classified information. These signals can be intercepted with the help of special equipment.

Radio interference generators are designed to operate within active information protection systems (APS)enabling information security against data leaks through the TEMPEST channels by generating a broadband noise electromagnetic interference on the edge of the control zone. Such interference noises out the stray radiation of the protected item.

Generator through the 230 V power grid with the frequency of 50 Hz (phase, neutral and ground) and to prevent unauthorized data retrieval through TEMPEST channels, 0.01-2,000 MHz.

It designed to actively protect informatization equipment against data leaks through the 220 V power grid with the frequency of 50 Hz (phase, neutral and ground) and to prevent unauthorized data retrieval through TEMPEST channels by generating broadband noise electromagnetic interference in the frequency band of 0.01-2,000 MHz.

The device is an average analogous stochastic generator loaded on antennas that are located in the device's power cord and on the telescopic antennas that are located in the Product's case.

It fed off of the AC circuit with the voltage of 230 V and frequency of 50 Hz. The device can be operated round the clock.
