Abstract

It is a proven fact that wireless local area networks are less secure as compared to fixed networks. Since, it is very easy for an intruder to learn the authorized addresses and change MAC addresses accordingly. MAC address spoofing is an easy task for hackers, as many tools available in the market that alter MAC addresses. In this paper, we propose a methodology based on the performance/result of different training functions using Backpropagation algorithm of ANN. The methodology does not require any change in IEEE 802.11 protocols and experience a small performance overhead. Keywords: Authentication; ANN; Back Propagation Algorithm; MAC Address Spoofing; Training Functions; WLAN.
