Abstract: Traditional Rogue AP detection methods are based on AP hardware fingerprint and traffic feature, but these two features are easy to be attacked by the attacker. In this paper, Aiming at the position of the terminal and the gateway is stable under the Smart Home environment,We proposed a CSI-based Rogue AP detection method. This method converted the detection of Rogue AP to the detection of the locations of AP.The method is divided into collection stage and detection stage. In the Collection stage, collecting the target AP location information as a fingerprint and build a fingerprint library in the security environment. In the detection stage,detecting the location information of the current connected AP and comparing with the information in the fingerprint library to determine the security of the current AP. Experiments show that this method is feasible and successfully solved the problem that the traditional Rogue AP detection method is easy to be bypassed.
