Access point selection mechanism to circumvent rogue access points using voting-based query procedure

One of the challenging issues in wireless network is rogue access point (RAP) detection and mitigation. The authors propose a new access point (AP) selection mechanism to keep wireless users from RAPs. A centralised server called AP registration centre (APRC) maintains a list of authorised APs, and a wireless user can check if a specific AP is legitimate by querying APRC about its legitimacy in a secure way using the concept of voting and signal strength-based authentication. The authors compare their scheme with a timing-based scheme and the experiment results show that our scheme detects RAPs accurately with lower false positives and false negatives.
