Security Algorithms to Prevent Denial of Service (DoS) Attacks in WLAN

Free registration required

Executive Summary

This paper proposes security algorithms which are used to mitigate the Media Access Control (MAC) layer Denial of Service (DoS) attacks in WLAN infrastructure networks. This paper is aimed to attend the DoS attacks due to the susceptibility of the MAC layer's management frames. The management frames are sent unencrypted; this makes the intruder easily spoof the MAC address of the client or Access Point (AP) and stops their communication. There are two algorithms proposed in this paper namely, the Intruder Detector and Manager (IDM) and Letter Envelop Protocol with Traffic pattern filtering (LEPT).
