This work presents the development of a novel method for encrypting text objects to enhance information security and provide protection against cybercriminals (crackers, hackers). The proposed approach moves away from the traditional use of single-character (unigram) numbering in the encryption alphabet. Instead, it utilizes numbered linguistic elements-such as word roots, syllables, bigrams, and trigrams-as the foundation for creating a unique (private) alphabet. The algorithm details the process of decomposing plaintext into these elements, their arbitrary numbering, and the subsequent application of a private key (using the Vigenère cipher as an example). It is demonstrated that the use of unique, multi-component alphabets significantly increases the cryptographic strength of the ciphertext. While the proposed encryption method is universal in its applicability to various languages, its specific implementation and effectiveness are closely dependent on the grammatical and linguistic features of the source language.
