基于智能手机的伪基站检测方法

Detection Method for Pseudo Base Station based on Smart Phone

GSM网络有自身的安全缺陷,采用的是单向认证机制,使得不法分子有机可乘。伪基站技术便是利用这一脆弱性,发送垃圾短信、诈骗短信、严重影响正常通信,已然成为2014年国家重点打击对象。针对以上问题,在Ubuntu平台上结合USRP硬件和OpenBTS、GNURadio等软件所搭建的环境对伪基站功能进行模拟,根据伪基站信号特征和工作原理,在此基础上,利用智能手机所有收集到的基站信息,发现一种检测伪基站信号的方法,此方法可以检测出大部分的伪基站信号,给打击伪基站带来了一定的帮助,可以达到一定防治伪基站的效果。

GSM network has its own security flaws,and adopts a one-way authentication mechanism,thus leaving a security loophole to the lawbreakers of all description.Pseudo base-station technology just makes full use of this vulnerability,sends spam and phishing messages,and thus seriously affects the normal communication.And those lawbreakers from pseudo base-station become the crack-down targets of the country in 2014.To solve the above problems,the environment is constructed on the Ubuntu platform in combination of USRP hardware with OpenBTS,GNURadio and other softwares,and in this environment,the functions of pseudo base-station is simulated.In accordance with the signal characteristics and working principle of pseudo base-station,and by using all the information collected from smart phones,a method to detect signal of pseudo base station is defined.This method could discover most of the pseudo base—station signal and offer some assistance to cracking down pseudo base-station,and this could surely achieve certain effect in preventing pseudo base-station.
