Rogue access point detection using segmental TCP jitter

Rogue Access Points (RAPs) pose serious security threats to local networks. An analytic model of prior probability distribution of Segmental TCP Jitter (STJ) is deduced from the mechanism of IEEE 802.11 MAC Distributed Coordinated Function (DCF) and used to differentiate the types of wire and WLAN connections which is the crucial step for RAPs detecting. STJ as the detecting metric can reflect more the characteristic of 802.11 MAC than ACK-Pair since it can eliminate the delay caused by packet transmission. The experiment on an operated network shows the average detection ratio of the algorithm with STJ is more than 92.8% and the average detection time is less than 1s with improvement of 20% and 60% over the detecting approach of ACK-Pair respectively. Farther more no WLAN training trace is needed in the detecting algorithm.
