“…Thus, the AP will not be able to update its database and used the old MAC address. Nguyen et al [8], used letter-envelop protocol (LEP) to authenticate management frames. The unprotected management frames carried the MAC address of source, so an attacker can easily perform de-authentication and disassociation attacks by spoofing MAC address.…”

Wireless Local Area Network (WLAN) is an infrastructure network in which nodes are connected to a centralized system to provide Internet access to mobile users by radio waves. But WLANs are vulnerable to Medium Access Control (MAC) layer Denial of Service (DoS) attacks due to the susceptibility of the management frames. An attacker can spoof the MAC address of the legitimate client and perform de-authentication attack to disconnect WLANs users from the access point. Many free tools are available in Kali Linux Operating System (OS) by which this attack can be performed and cause a security threat to WLAN users. The consequences of de-authentication DoS attack are frequent disconnection from Internet, traffic redirection, man-in-the-middle attack, and congestion. Despite enormous efforts in combating de-authentication DoS attack in the past decade, this attack is still a serious threat to the security of the cyber world. Medium Access Control Spoof Detection and Prevention (MAC SDP) DoS algorithm performs detection and prevention of de-authentication attack caused by spoofing MAC address. This algorithm is modified to make it more immune to the de-authentication attack and implemented in real-time scenario. The results show that the proposed technique increases the packet flow rate by 20.36%, reduces the packet loss by 95.71%, and reduces the down time and recovery time by 0.39 sec and 0.9 sec respectively as compared to MAC SDP DoS algorithm.

“…A lightweight authentication solution for dissociation DoS attacks, based upon Letter‐Envelop Protocol, is proposed by Nguyen . The STA during association phase generates two strong random numbers (say p, q) and then computes N = p * q.…”

“…There are few solutions (Category V, Table ) that are proposed, keeping in view the DoS threat caused using deauthentication/disassociation frames. The secure wireless scheme is similar to other spoof‐reducing schemes of Category I. Letter‐Envelop Protocol is a small but effective scheme to protect against deauthentication/disassociation DoS attacks. Here, the computation time is required to calculate the prime numbers, and the frame is modified to accommodate the prime numbers.…”

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. Copyright © 2014 John Wiley & Sons, Ltd.
