ABSTRACT

As the installation of Wi-Fi in public spaces becomes increasingly common, security threats are intensifying in network environments where no password is set or a shared password is used by many users. In particular, since sensitive personal information of users can be stolen through Evil Twin attacks, security enhancement measures are required. In this paper, we propose a RADIUS server-based random account generation system (R-RAGS, RADIUS-based Random Account Generation System) as a method to fundamentally block Evil Twin attacks by allowing each user to use a different password. The proposed system consists of a Spring Boot-based web server, a RADIUS server, and MariaDB, and is implemented as open source so that anyone can use it. Through experiments, we confirmed that Evil Twin attacks are virtually impossible in Wi-Fi environments where the proposed system is applied because random passwords that cannot be guessed by outsiders are individually assigned to each user. This study presents an open code-based approach to enhance public Wi-Fi security, and we expect that the proposed system will be applied to various public places to contribute to creating a safer wireless network environment.
