Chechelnitsky V. Methodology improve telecommunication systems based on the integration of channel coding and data encryption.

The thesis is devoted to solving the problem of information security in communication channels with interference by means of combining the methods of encryption and error-correcting coding performed on the basis of the development of methods for the synthesis of complete classes of perfect algebraic structures with ideal correlation and distance properties: perfect multi-level arrays, perfect binary arrays, ensembles of signals with perfect periodic autocorrelation functions, one- and two-dimensional block error-correcting codes to correct both independent and correlated (packet) errors. In solving the problem the principle of operational change of working ensembles of noise-like signals and error-correcting codes based on the key derivation function was implemented, which allowed to increase noise immunity, parametric secrecy and protection of information from unauthorized access. In addition, the paper considers a number of issues related to the technical implementation of joint encryption/channel coding device and joint decoding/channel decoding device.
