METHOD OF SAFE CODING INFORMATION FOR ITS TRANSMISSION OVER OPEN COMMUNICATION CHANNELS USING STEGANOGRAPHY TECHNIQUES Russian patent published in 2018 - IPC H04L9/00 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to a method of safe encoding information for its transmission over open communication channels using steganography techniques. In this method an exchange is carried out between distant stations by secret keys K_encr and K_steg, open message M_j can be pre-encrypted using encryption key K_encr, cryptogram C_j is obtained, which is further transmitted as per the method, herewith together with the keys the distant stations exchange two tables of numbered pairwise simple modules, the transmitted data is represented in an extended modular code (n information deductions and r control ones) over a system of the pairwise simple modules in such a way, that parts of the transmitted payload are taken as n modular code deductions, ; to the received deductions the service information necessary for restoration of the lost/distorted at the transfer of the information is added.

EFFECT: technical result is to increase the noise immunity of the transmitted information.
