Design and Implementation of a Holistic and Robust Wi-Fi Authentication and Authorization Framework for Secure Wireless Networks

Abstract

Wireless networks have become a significant portion of existing systems of communication, giving suitable and elastic connectivity. Wi-Fi networks have evolved to be everywhere in our day-to-day lives, and with this growing service, the security dangers associated with wireless networks have also expanded. Our work suggests a holistic and robust Wi-Fi authentication and authorization framework for safe networks. The suggested framework includes three main components ( authentication, authorization, and encryption). The authentication utilizes a secure password-based authentication protocol to authenticate users and devices on the wireless network. The authorization utilizes network segmentation and access control to limit unauthorized access and mitigate attacks. Eventually, the encryption utilizes the Advanced Encryption Standard (AES) algorithm to guarantee confidentiality in addition to the integrity of wireless communications.  Evaluate the efficacy of the suggested framework based on the executed experiments utilizing the OMNeT++  simulator. The outcomes demonstrate that the framework provides robust security against a variety of attacks, such as eavesdropping, man-in-the-middle attacks, and denial-of-service attacks. Also, the suggested work was discovered to have minimal influence on network performance, with only a slight increase in latency and a modest decrease in throughput.
