METHOD AND DEVICE FOR FORMING MODIFIED CRYPTO-CODE STRUCTURES FOR NOISE-RESISTANT DATA TRANSMISSION OVER COMMUNICATION CHANNELS Russian patent published in 2024 - IPC G06F11/08 G06F21/60 

FIELD: cryptographic information protection.

SUBSTANCE: method for forming modified crypto-code structures for noise-resistant data transmission over communication channels is ensured by constructing crypto-code structures, the essence of which is to combine block encryption algorithms and multi-valued noise-resistant codes. A sequence of ciphertext or plaintext blocks or ciphertext blocks and a simulated insert generated from them, formed from a message M, is represented as a single information superblock of modular code, on the basis of which one or two redundant data blocks are formed. In this case, a simulated insertion and a redundant block or two redundant blocks are represented as a pseudo-complex number. Next, the objectivation procedure is performed. From the set of generated sequences of cipher or plaintext and real deduction, a data array is formed, which is transposed to form an error-resistant sequence of cipher or plaintext.

EFFECT: increasing resistance to deliberate simulating influences of an attacker.
