Research on Phishing AP Attack Detection Technology Based on RSSI

Wi-Fi wireless technology obtained rapid development because of its flexibility, mobility and easy scalability characteristics. But the network identifier (SSID, BSSID) is easy to be forged, the attacker is easy to forge AP that a common user can't identify it, and conduct other attacks, then get the user's sensitive information. In this paper, we propose an improved RSSI phishing AP attack detection method based on the characteristics of RSSI in wireless Wi-Fi network and easy to obtain. The method needs to be in a safe and secure environment construction of Wi-Fi wireless RSSI fingerprint database and the detected target AP and fingerprint library information were compared to determine the safety, solving the problem of twin fishing AP successfully. Experimental results show that in the RSSI threshold with the range of -5dBm, the correct detection rate can reach 95%, to achieve the legitimacy of the WLAN AP detection.
