Mail client with data transfer protected with end-to-end encryption

Abstract

This article is devoted to the study of the issues of secure messaging and file exchange by e-mail at the enterprises of the agro-industrial complex. The purpose of this work is to develop an algorithmic support and software of mail client that supports the functionality of end-to-end data encryption. The following research methods are used in the article: comparison method, observation method, structural analysis method. The comparison method is used to identify differences between key distribution protocols. Methods of observation and analysis make it possible to understand the behavior of various protocols within systems that differ in technical and software properties. The article consists of four parts: Introduction, Materials and Methods, Results, Conclusions. The first part describes the relevance of the topic, discusses the features of various cryptographic protocols. The second part describes the developed algorithms that ensure the operation of the mail client and end-to-end data encryption. The third part discusses the results of software implementation of the developed algorithms. In the fourth part conclusions are made and summed up. The main results of the work are algorithmic implementation of software for local architecture based on the use of symmetric cryptography; a software tool designed according to a local scheme, including modules that allow you to develop a system on a client-server architecture.
