A Mobile Device-Based Mobile AP Detection Scheme Using NAT Behavior

This paper proposes the scheme to detect the Mobile AP from mobile devices independently without the help of additional nodes. The proposed scheme is for detecting the Mobile AP that does not have any security configuration which is highly likely to occur as the Rogue AP in real wireless network environment. The device inspects the NAT Behavior and Open Port at the time of specific AP connection to detect the presence of Mobile AP, and reduces the security threat for the Rogue AP. The Rogue AP detection scheme s presented previously are generally based on the detection of Rogue AP in the form of Evil Twin, and the Rogue AP of various forms cannot be detected easily with such techniques. In addition, such techniques require regular monitoring or additional network infrastructure, thus making it difficult to apply to mobile devices, and are not suitable in real public wireless network environment. The proposed technique enables detection of mobile AP, which does not have any security configuration, from mobile devices in public wireless network environment independently without the help of additional nodes, and therefore, represents the detection scheme that is easily applicable and proved its performance in the experiment under real wireless network environment.
