Mathematical modeling of information leakage prevention processes on parametric channels in of management activity

It is noted that control bodies are installed in which the main and auxiliary technical means and systems (MTM and ATM, respectively) are installed, used in the process of management activities, as well as the so-called semi-active stowing devices introduced in these rooms serve as a source of informative signals. in the field of these signals of some parameters in the element database included in the MTM and (or) ATM. The necessity of a systematic presentation of formal conditions characterizing the dynamics of counteraction to the interception of electromagnetic radiation arising from changes in the parameters of the radioelectronic devices of the reconnaissance object under the influence of an informative signal on the element base of these devices and external high-frequency electromagnetic irradiation, as a prerequisite for ensuring a high level of adequacy of assessing the effectiveness of countermeasures to technical intelligence (CMTI) to prevent information leakage through parametric channels. The structure of a set of mathematical models for evaluating the performance indicator is described. Analytical models of the temporal characteristics of threats to intercept information through parametric channels and measures to prevent its leakage are given. The probabilistic format of the indicator of the effectiveness of such measures is substantiated. The results of a computational experiment to substantiate the requirements for the characteristics of the means of CMTI are presented.
