Аннотация. The theft of digital data problem is receiving growing attention. This situation can produce losses in the organisation's finances, when the used cybersecurity strategy, it is not adequate such as the employment of static encryption methods. There exist several safe alternatives based on standard encryption algorithms such as AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), to mention a few. However, it is known that these algorithms, they have been threatened by quantum computing advent. In some cases, it has been handled with dynamic encryption methodology, which it can create different ciphertext results with the same plaintext input. This schema can help to mistake the cybercriminals. In this paper, several aspects related to this subject, they are here studied although quantum computing is not used in this work, other measures have been proposed. We recommend the replacement of static encryption method by another dynamic alternative. Recent proposals recommend using pseudo-hexadecimal encoding with artificial intelligence. This research is future work of these strategies because it has been observed that these proposals, they can take a long time for processing. This situation might be very good for data protection of the organisations. That's why the importance of our work because that pseudo-hexadecimal encoding with artificial intelligence schema, it has been presented as a good alternative. Regarding the research's aims, they consist in the noisy injection and to avoid that ciphertext can be decrypted by cybercriminals. Four novel proposals based on pseudo-hexadecimal noisy injection strategy that they were named here as noisy random pseudo-hexadecimal standard version, noisy random pseudo-hexadecimal by substitution, noisy random pseudo-hexadecimal by shifting, and noisy random pseudo-hexadecimal version 2, they are here recommended as dynamic encryption alternatives. Finally, the comparison of results with some standard encryption algorithms, it is also introduced.
