Застосування асиметричного шифрування в електронній пошті для забезпечення конфіденційності та автентичності повідомлень

Abstract

The paper explores the use of asymmetric encryption in email communication as a key mechanism for ensuring message confidentiality and authenticity. It analyzes the operational principles of major asymmetric algorithms (RSA, ECC), their advantages over symmetric methods, and key implementation standards (PGP/GPG, S/MIME). Particular attention is given to data protection mechanisms, including content encryption and digital signatures for verifying authorship and preserving message integrity. The study highlights the challenges of key management and integration of encryption technologies into modern email systems. Prospects for the implementation of asymmetric encryption in enhancing the cybersecurity of governmental and corporate communications are outlined.
