New products on the information security market

New products on the information security market

Held from February 1 to 5 2000, at the All-Russian Exhibition Center forum «Security Technologies», the «Information Protection» company presented information security technology from American companies Research Electronics Inti and Information Security Associations (REI). REI products are well known to Russian consumers and rightfully enjoy deserved popularity. Several publications were devoted to REI devices in the journal «Security Systems, Communications and Telecommunications» (1996, No. 4; 1999, No. 24; 1999, No. 26). This article provides a brief overview of the new products from this company. First of all, these are new versions of software and a software key for working with the OSCOR spectral correlator, as well as the MDC-2100 converter, ORION nonlinearity locator, ECR-2 spectrum analyzer, ECR-Smart Scan software interface

ORS-50003.0

At the end of 1999, REI introduced a new version of the OPC5000 3.0 software product for OSCOR. Unlike the previous version 2.3, the new software allows you to fully control the correlator from a personal computer, save user settings, as well as graphic spectral images of selected frequency bands.

The new product makes it possible to obtain a spectral picture in real time on the screen of a personal computer, as well as the result of its comparison with a previously saved frequency panorama (Fig. 1).

In addition, the new product implements an additional digital correlation method (Fig. 2), which makes it possible to determine whether a given signal belongs to an eavesdropping device or not. In case of a positive result, you can determine the distance to it (Fig. 2a).

All these operations can be performed either manually by the operator or automatically. The source of the reference audio signal for correlation is either the natural noise of the room (operation of office equipment, speech) or a white noise signal emitted by a special generator. REI also offered a new version 3.0 of the software key for working with OSCOR. It allows you to operate not only with signal databases, as was implemented in previous versions, but also to store graphic spectral images of frequency panoramas in the device’s memory. During the search process, the operator can receive on the OSCOR screen the result of comparing the real spectrum with a previously saved panorama and, accordingly, quickly select new signals. The new version of the software key assumes operation on devices with an installed OEM-5000 extended memory module. When using OEM with version 3.0, the resolution of the spectral band stored in the device memory from 5 MHz to 3 GHz is 50 kHz, and without it 100 kHz. The signal database has a capacity of 7168 and 3072 signals, respectively.

MDC-2100 Converter

REI is completing work on the production of the MDC-2100 converter, which will expand the OSCOR operating range to 21 GHz. The new device is designed to work only with the OSC5000, is controlled by its processor and does not require any hardware changes to the OSCOR. MDC-2100 has three divided operating bands:

•3-9 GHz:

•9-15 GHz;

•15-21 GHz.

These ranges will be displayed by OSCOR independently or continuously during a quick search. The converter has three built-in active antennas for each band. The Information Security company plans to demonstrate the MDC-2100 (Fig. 3) at the MIPS-2000 exhibition in April 2000.

ORION nonlinearity locator

The REI ORION nonlinearity locator with analysis of the 2nd and 3rd harmonics, which appeared on the market at the beginning of 1999, has already found its consumer. Ergonomic design (no connecting wires and weight less than 2 kg) made the complex electronic device simple and easy to use. All the advantages of ORION (Fig. 4) were discussed in detail in an article by REI CEO Thomas Jones in the journal Security, Communications and Telecommunications Systems (1999, No. 26).

OSC-5000 Spectral Correlator

OSCOR (certificate of the State Technical Commission No. 81), is a multifunctional device or, rather, several devices in one (Fig. 5).

First, OSCOR is a spectrum analyzer ranging from 10 kHz to 3 GHz with a best resolution of 50 Hz. On its screen you can observe the spectra of signals from both LF and HF modulated transmitting devices, evaluate their deviation and amplitude (the dynamic range of the device is 90 dB).

Secondly, OSCOR is a tunable, sensitive (0.8 μV in the 15 kHz band) wideband receiver with a set of demodulators, which allows the user to isolate an informative audio signal even in difficult interference conditions. Its maximum tuning speed is 93 MHz/s with a bandwidth of 250 kHz.

The receiver has several analysis inputs:

• the radio channel covers the range from 10 kHz to 3 GHz and has three types of antennas (loop, whip and disc);

• the infrared detector is sensitive in the range of 0.85-1'.07 microns;

• network detector for examining wire lines with voltages up to 300 V — in the range of 10 kHz-5 MHz.

Thirdly, OSCOR is a digital correlator, which, when the device operates in automatic mode, allows you to determine whether the analyzed signal is a signal from a listening device or not.

The functionality of OSCORa is quite wide:

• radio broadcast analysis; in a wide range of frequencies in order to search for listening devices;

• control of telephone and wire lines;

• IR channel analysis.

The additional options offered significantly expand the capabilities of OSCORa. Thus, the OVM-5000 option, included in the OSC-5000 Delux kit, is designed to analyze video signals when searching for video transmitters.

ECR-2 Spectrum Analyzer

The ISA ECR-2 spectrum analyzer allows you to search for eavesdropping radio transmitting devices in the frequency range from 10 kHz to 1 GHz, as well as examine wired power and low-current lines. When using expansion modules, this range increases to 3 GHz (with MDC-5) or up to 7 GHz (with MDC-4). Unlike most similar instruments, the ECR-2 is a calibrated instrument and allows signal level measurements in dBm, dBµV/m or dBµV.

The ECR-2's CRT display can display spectral regions ranging from 100 kHz to 1 GHz. This device has built-in amplitude and frequency demodulators with variable bandwidth, which allow you to listen to audio signals, and an output for analyzing video signals. The removable memory card of the device allows you to store information about user settings and 40 graphic images of frequency bands, which can later be easily recalled from memory by the operator. Using the built-in plotter, you can quickly record a spectral image (Fig. 6).
ECR-Smart Scan software interfacegreatly simplifies the operator's work. It allows you to create databases and spectral images, perform subtraction operations with them, highlighting new signals. ECR-2 (Fig. 7) can operate in three modes.

Searching for a signal. The device automatically tunes in frequency, detecting all signals, and determines their frequency and power. It then automatically tunes to each signal and demodulates it, allowing the operator to recognize the signal from the listening device. All signals are saved on the computer's hard drive for later analysis.

Comparative analysis. When scanning, a continuous comparison of the current spectrum with the previous one is performed and only new signals or signals whose power has increased are displayed.

Automatic detection. In this mode, each signal is automatically demodulated. The computer analyzes it and compares it with the acoustics of the room being examined. When a transmitter is detected, the operator receives an alarm.
