“…The following expressions (1) -(15) are mathematical models for estimation of average values of time of realization of operation modes of TCP during illegal actions on interception of information via parametric channels. In accordance with the order of operations, given in [1,4], performed by an intruder in the process of configuration of AP equipment through the channels of acousto-electrical transformations, HF irradiation, parasitic (auto) generation and HF imposition, the average value (p11) of the random value of time, spent by an intruder on the realization of this mode of TCR operation is determined in accordance with the expression:…”
