In this paper, the authors, on the basis of a software package ScicosLab, carried out a simulation
of the apparatus for protection against imitation of controlled objects with high structural security of
carrier signals with new set of chaotic signals. In the result of a simulation, when changes in the parameters
of a chaotic signal, based on qualitative indicators representing time and spectral diagrams
found that the simulated apparatus for protection against imitation of controlled objects with high
structural security of carrier signals in general copes with the task of encryption (the output signal has
a noise-like appearance) and recovery of the information signal (source information signal and the
recovered information signal have almost identical appearance). The distinctive feature of this apparatus
for protection against imitation of controlled objects with high structural security of carrier signals
is the possibility of using different chaotic signals that are recorded in rewritable drives chaotic
sequences. This fact allows to significantly increase the security of the radio link from unauthorized
access by third parties and opens the way for application of this technology not only in wireless fire
alarm, but in other areas as wireless security systems. In the authors’ opinion, further research in this
area should be conducted in the field of studying the applicability of other classes of chaotic signals
for the transfer of a protected communication and use of various pseudo-random sequences limited
by the range [ –1; 1] as an information signal.
