Text encryption through distributed systems

Abstract

In recent years, the exponential growth of interconnections between digital devices has led to a significant increase in cyberattack incidents, often leading to severe and disastrous consequences for an organization by exploiting existing vulne rabilities in emerging technologies. One of the most innovative and effective defense mechanisms is cryptography, considered an essential requirement in the cybersecurity community for data protection. In this paper, we implement encryption methods executed on each machine in a distributed manner through the Simple Object Access Protocol (SOAP) web service for the data that want to be protected. To achieve it, a distributed system was created with virtual machines that host encryption methods such as AES-256, Caesar, and Blowfish, to send encrypted data from a source machine to a destination machine and, in turn, decrypt the encrypted data. The results obtained were excellent because our proposal adds more security to the data, performing it difficult for attackers to obtain the data quickly. In addition, the consumption of computational resources for executing the algorithms in the distributed system is minimal, which is adequate to guarantee its use in any computer with limited resources.
