METHOD AND APPARATUS FOR GENERATING MULTI-VALUED CODE STRUCTURES FOR SECURE DATA TRANSMISSION OVER COMMUNICATION CHANNELS Russian patent published in 2024 - IPC G06F21/64 H04L9/06 

FIELD: electrical communication equipment.

SUBSTANCE: group of inventions relates to radio and electrical communication and can be used to protect information transmitted over open communication channels or stored on information media. Method comprises steps of, to blocks of plain text {M₁, M₂, …, M_k} procedure of structural-algebraic transformation is applied, which allows based on introduced complex module ṁ=p+qi perform a procedure of one-to-one conversion of a sequence of blocks of plain text {M₁, M₂, …, M_k} to protected representation in form of complex numbers {a₁+b₁i, a₂+b₂i, …, a_k+b_ki], expansion operation is performed, which enables for a sequence of complex numbers to calculate redundant elements {a_k+1+b_k+1i, …, a_k+r+b_k+ri} with subsequent formation of multi-valued code structures of the form 〈a₁, b₁i〉; …; 〈a_k, b_ki〉; 〈a_k+1, b_k+1i〉; …; 〈a_k+r, b_k+ri〉, in which a real part {a₁, …, a_k, a_k+1, …, a_k+r} and an imaginary part {b₁i, …, b_ki, b_k+1i, …, b_k+ri} are transmitted over the first and second channels of the two-channel transmitter, respectively.

EFFECT: high resistance of protected data to destructive effects.
