社交网络中定位欺骗攻击的防御机制

Defense Mechanism for Location Spoofing Attacks in Social Networks

为了降低用户在现有无线终端定位系统因遭欺骗攻击而造成隐私泄露的可能性,本文提出一种基于AccessPoint标签和Access Point位置的双校验方法的防御机制,通过构造Access Point标签,利用其不可伪造性和可再现性来校验Access Point的合法性,并结合Access Point位置,实现移动设备的鲁棒定位。

In order to reduce the possibility of privacy leakage caused by cheating attacks on the existing wireless terminal location system,the paper proposed a defense mechanism based on the dual verification method of AP label and AP location.By constructing the AP label,it used its unforgeability and reproducibility to verify the legitimacy of the AP.And combined with AP location,to achieve robust positioning of mobile devices.
