Shihao Yan, Robert Malaney, Ido Nevat, Gareth W. Peters

摘要:

随着基于位置的应用在新兴的无线网络中变得无处不在,位置验证系统(LVS)变得越来越重要。在本文中,我们首次提出了一个严格的信息理论框架的LVS。我们开发的理论框架说明了如何使用在欺骗位置的检测阈值可以优化的LVS的输入和输出数据之间的互信息。为了验证我们的分析框架的合法性,我们进行了详细的数值模拟。我们的模拟模拟的实际情况下,使用我们的框架部署的系统必须作出二进制是/否“恶意决定”的每个快照的基站获得的信号强度值。仿真和分析之间的比较显示出良好的协议。我们优化的LVS框架提供了一个防御位置欺骗攻击的新兴无线网络,如智能交通系统,位置信息的验证是至关重要的。

英文摘要:

As location-based applications become ubiquitous in emerging wireless networks, Location Verification Systems (LVS) are of growing importance. In this paper we propose, for the first time, a rigorous information-theoretic framework for an LVS. The theoretical framework we develop illustrates how the threshold used in the detection of a spoofed location can be optimized in terms of the mutual information between the input and output data of the LVS. In order to verify the legitimacy of our analytical framework we have carried out detailed numerical simulations. Our simulations mimic the practical scenario where a system deployed using our framework must make a binary Yes/No "malicious decision" to each snapshot of the signal strength values obtained by base stations. The comparison between simulation and analysis shows excellent agreement. Our optimized LVS framework provides a defence against location spoofing attacks in emerging wireless networks such as those envisioned for Intelligent Transport Systems, where verification of location information is of paramount importance.
