Summary/Abstract: With the increasing complexity and interconnectivity of networks, numerous cyber threats have emerged, including data interception, packet manipulation, man-in-the-middle attacks, spoofing, and Denial-of-Service (DoS) attacks. In response to these risks, data encryption stands out as one of the most effective strategies for safeguarding the confidentiality and integrity of information transmitted over networks. This study aims to analyze and compare several encryption methods employed in securing communications within computer networks, using simulations conducted in the MATLAB environment. Data encryption scenarios will be implemented, and the performance of the algorithms will be assessed based on metrics such as execution time, key size, and the impact on communication latency.
