On the IEEE 802.11i security: a denial‐of‐service perspective

The IEEE 802.11i standard provides authentication and security at the Medium Access Control layer in wireless local area networks (WLANs). It involves an authentication process followed by a four‐way handshake to evolve a key for securing data sessions. The standard suffers under denial‐of‐service (DoS) attacks. These attacks often block the ongoing communication process and deprive services to the legitimate users. These are easy to conduct while maintaining anonymity of the attackers. It hence becomes imperative to learn about the attacks and their solutions in IEEE 802.11i‐protected WLANs so that future research proposals and solutions to mitigate the attack may develop. The paper presents a review of DoS attacks and existing solutions pertaining to the IEEE 802.11i security standard.
