摘　　要：利用GSM协议的一个缺陷,提出一个对GSM用户定位的方法.当用户使用GSM移动电话时,攻击者修改GSM移动电话和基站之间在空中接口传输的一些信令报文子域,诱使GSM移动电话向基站明文传输IMSI和IMEI身份标识符.这种攻击方法能让通信双方对攻击没有察觉,从而保证攻击的隐蔽性.攻击者根据截获的IMSI和IMEI,以及用户所属区域的LAI即可实现对用户的定位.A theoretical method for locating GSM mobile user is presented. With it the attacker can spoof the mobile phone to send its IMSI and IMEI identifiers to the air by changing the messages transmitted between the mobile phone and the base station. After intercepting IMSI and IMEI, the attacker can locate the mobile phone user through LAI received from the broadcast messages of the current base station. Both mobile phone user and the base station are not aware of the action of locating during this attacking procedure.
