Abstract
The significance of this research lies in safeguarding user information and data against unauthorized alterations and destruction. Throughout the study, key aspects were explored, including user identification and authen-tication methods, cryptographic authentication protocols, digital signature properties, and strategies to enhance the cryptographic robustness of digital signatures. These strategies involved scrutinizing authentication methods using the Saati technique and the RSA algorithm. The analysis revealed that the attributes employed for digital signature recognition are highly resistant to replication, and the verification process is notably efficient. The height-ened cryptographic resilience of the electronic signature achieved through the RSA algorithm stems from the incorporation of a public key certificate. Consequently, a larger encryption key size corresponds to heightened sys-tem reliability and electronic digital signature security. While the utiliza-tion of the RSA algorithm results in encrypted text that is approximately 10 times larger than the original, its stability is comparatively increased.
