The object of research is the method and result of the synthesis of broadband noise-like signals. The subject of the study is to organize the protected channel of the radio allowing to realize on the basis of a common ideology steganographic and cryptographic security model of the data transmitted. The method and software implementation of the synthesis of true complex-valued noise-like signals. The proposed method allows to effectively control the range of the broadband signals. Comparative statistical analysis of the proposed wideband signals with signal synthesized by the harmonic functions and wavelet functions on the basis of the matrices with a special form of the autocorrelation function. Good value Central spike to the side lobes of the autocorrelation function allows you to identify the proposed broadband signals hidden in the noise of the radio that determines the possibility of using signals in the task hidden (steganographic) communications. A relatively small computational complexity of the synthesis algorithm by pseudo-random law, with a significant number of potential broadband signals allows to implement encryption of radio traffic. Encryption radiosonding can be realized by eliminating the transmission of repetitive signal symbols in a communication session. In the work produced by the preliminary statistical analysis of the characteristics of the signals. Proposed conceptual organization model of a cryptographic channel of transmission of radio signals. In conclusion, the work concludes. The work is performed on the basis of the Saint Petersburg National Research University of Information Technologies, Mechanics and Optics (ITMO University).
