METHOD AND APPARATUS FOR FORMING CRYPTOCODE STRUCTURES FOR IMITATION-RESISTANT DATA TRANSMISSION OVER COMMUNICATION CHANNELS Russian patent published in 2022 - IPC G06F11/08 G06F21/60 

FIELD: information security.

SUBSTANCE: invention relates to the field of information processing, more specifically, to apparatuses and methods for cryptographic protection of information. The technical result is achieved due to the execution of the following stages: presenting a message in the form of fixed-length blocks; applying k encryption procedures to plaintext blocks according to the corresponding key; presenting the resulting encrypted text blocks in the form of the least non-negative residues for the generated relatively prime modules, arranged by magnitude; forming an information superblock of modular code; executing the operation of expanding the information superblock of modular code and obtaining redundant data blocks; applying the block encryption procedure to the redundant data blocks; obtaining redundant encrypted text blocks and forming cryptocode structures of the imitation-resistant sequence of the encrypted text.

EFFECT: increase in the resistance of transmission of encrypted information to deliberate imitating impacts.
