Abstract

The justification of the decision scheme for the construction of the receiver in order to realize the possible detection of signs of signals in space is carried out.In accordance with the condition regarding the impossibility of detecting signs of dangerous signals, the criterion of optimality is substantiated for the construction of the decisive scheme of the receiver. It is obtained by the maximum unmasking of information signals, pursuing the fulfillment of the security condition, as for the worst case. That is, if signals with more unmasking features, for example, power, are not detected, then signals with less unmasking features will not be detected either. On the basis of the obtained optimality criterion, a corresponding decision scheme of the optimal receiver is constructed. The proposed scheme considers three hypotheses: there are no signs of a signal, the impossibility of reliably determining the signs of a signal, and signs of a signal are present.On the basis of the specified decisive scheme, its special case is obtained, which describes the condition of the impossibility of reliably detecting the signs of a dangerous signal at the time when ICS or technical means of information processing and transmission are working. The discrete-continuous channel using the specified scheme allows to simulate the technical channel of information leakage, as for the worst case from the point of view of security, and to find the probability of the impossibility of reliably detecting the signs of a dangerous signal. Obviously, this probability will determine the probability of a security risk.
