Introduction
In an increasingly digital world, electronic voting (e-voting) systems are emerging as crucial components of democratic processes. These systems leverage advanced cryptographic protocols and blockchain technology to enhance the security, transparency, and reliability of elections. This paper, authored by Tolegen Aidynov, Nikolaj Goranin, Dina Satybaldina, and Assel Nurusheva, systematically reviews the literature on the current trends in e-voting system protection, aiming to map out the key advancements and directions in this field.
Overview of Electronic Voting Systems
Electronic voting systems offer significant advantages over traditional voting methods, such as increased efficiency, accessibility, and speed in vote counting. However, these systems also face substantial challenges, particularly in ensuring security and confidentiality. The authors highlight the importance of cryptographic protocols and blockchain technology in addressing these challenges.
