METHOD FOR BYTE-BY-BYTE TRANSMISSION OF INFORMATION USING STREAM ENCRYPTION Russian patent published in 2024 - IPC H04L9/06 H04L9/16 

FIELD: data encryption.

SUBSTANCE: SQ state matrix is created by writing numbers in order from 0 to 255. The option of constructing a KQ auxiliary key matrix is selected. The KQ auxiliary key matrix is calculated. The resulting SQL state matrix is calculated using the formula: SQL = SQ ⊕ KQ mod 256. The numeric values of the SQL matrix elements acre converted into the binary number system corresponding to the ASCII character table. Plaintext characters are written using the ASCII character table yielding the value of character X_i corresponding to the plaintext character, written in the binary system. One byte of ASCII characters, and one byte of an SQL matrix element, and one byte of X_i characters are summed by modulo two to obtain the encrypted message Y_i. The encrypted message Y_i is transmitted.

EFFECT: reduced time of encryption and decryption of text.
