无线局域网中位置仿冒的可行性分析

he security of WLAN is the hot research area in wireless networks. Although there are plenty of works for security, mainly of them focus on the data security and communication protocol's security problems. As some applications are emerged that based on location information, the users' location security has received growing attention. The location based applications need to consider the users' location security. But as an attacker, it wants to hide its real location. This paper devotes to the angle based location theory and technology, analyses a spoof scheme's probality that deal with the angle information. If the multipath signal's a reflection angle is controllable, it can successfully spoof the location system. By simulation, we demonstrate the effectiveness of the scheme under symmetric and non-symmetric network scenarios
