Abstract
The article considers the physical basis for the formation of a technical channel of information leakage that occurs due to low-frequency acoustoelectric transformations. The method of instrumental and computational control of the security of speech information in the considered channel of information leakage, which is currently used in special research, is presented with a representation in the form of a simulation model. Based on the developed simulation model, using the MVR design pattern, a software tool was developed. The main classes of software that implements the model are presented. The functionality of the developed software tool is demonstrated and recommendations are given for the possible use of a simulation model for identifying threats to information security that occur due to low – frequency acoustoelectric transformations.
Highlights
The technical protection of information is becoming increasingly important
The technique is intended to assess the protection of acoustic speech information from leakage resulting from low-frequency acoustoelectric transformations, when informative signals containing acoustic speech information can be recorded as electrical signals in communication lines of technical equipment, in the ground bus, in the wires of the power supply network, and when the technical means (TM) is exposed to sound vibrations arising during pronunciation or speech reproduction
A simulation model for identifying threats to information security breaches arising from LF AEС is implemented by means of a software tool, the components of which were developed in the C # language, using the .NET Framework 2.0 - 4.5.2. in the development environment Unity3D 2018.4 and JetBrains Rider
Summary
The technical protection of information is becoming increasingly important. As TMR, for example, low-noise amplifiers of low frequency with a high gain and special sets of connection elements can act [5, 11, 13, 14, 16, 17]. Such channels of leakage are created due to the phenomenon of acoustoelectric conversions (AEC) in the elements of technical means
