报告题目:Where Are You From?Confusing Location Distinction Using Virtual Multipath Camouflage

报 告 人:Dr.Yao Liu

报告时间:2017614日(周三)14:30-16:30

报告地点:通信与信息工程学院楼106

报告摘要:In wireless networks,location distinction aims to detect location changes or facilitateauthentication of wireless users. To achieve location distinction, recentresearch has been focused on investigating the spatial uncorrelation propertyof wireless channels. Specifically, the differences of wireless channel

characteristics are used to distinguishlocations or identify location changes.

However, we discovera new attack against all existing location distinction approaches that arebuilt on the spatial uncorrelation property of wireless channels. In such anattack, the adversary can easily hide her location changes or impersonatemovements by injecting fake wireless channel characteristics into a targetreceiver. Experimental results on our USRP-based prototype show that thediscovered attack can craft any desired channel characteristic with asuccessful probability of 95.0% to defeat spatial uncorrelation based locationdistinction schemes. To defend against this attack, we propose a detectiontechnique that utilizes an auxiliary receiver or antenna to identify these fakechannel characteristics. Experiments demonstrate that our novel detectionmethod achieves a detection rate higher than 91.2% while maintaining a very lowfalse alarm rate.

  Inthis talk, I will introduce this discovered attack and the proposed defensemethods.
