METHOD AND DEVICE FOR MULTIDIMENSIONAL IMITATION RESISTANCE TRANSMISSION OF INFORMATION OVER COMMUNICATION CHANNELS Russian patent published in 2019 - IPC G06F11/08 H04L9/06 

FIELD: cryptography.

SUBSTANCE: invention relates to cryptographic protection of information transmitted over open communication channels or stored on data media. Method for imitation-stable information transmission over communication channels, in which a sequence of ciphertext block Ω_i(z) (i=1, 2, …, k) generated from message M(z) is divided into k₂ sub-blocks containing k₁ ciphertext block Ω_i(z) in each, which are represented in form of matrix W of size k₁×k₂, wherein columns of matrix W are sub-blocks of k₁ ciphertext units Ω_i(z), generating for each row of matrix W redundant data blocks, which are subjected to block coding procedure, performing for each of columns of matrix W redundant data blocks, which are subjected to procedure of block coding, obtained units of redundant ciphertext of 1st and 2nd control levels and redundant blocks of data form multidimensional crypto-coded structures, i.e. imitation resistance sequence of coded text.

EFFECT: high stability of transmitting encrypted information to intentional simulating actions of an intruder.
