Simulation of apparatus for protection against imitation of controlled objects with high structural security of carrier signals
In this paper, the authors, on the basis of a software package ScicosLab, carried out simulation of
apparatus for protection against imitation of controlled objects with high structural security of carrier
signals, aimed at the substantiation of its practical use for secure information exchange between
the sensors and the control unit in the radio fire alarm systems. In the result of a simulation when
changes in the parameters of a chaotic signal on the basis of quality indicators in the form of graphs
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.
