摘要
根据当前手机用户卡的安全现状,复制并测试了SIM卡,分析讨论了GSM手机用户卡检测机制。在此基础上,开发了疑似克隆卡检测系统,经过在吕梁局下测试验证,结果可以呈现疑似克隆卡告警,同时结合用户通话话单、停开机日志等,基本上可以判断用户的SIM卡是否被复制。
According to security status of SIM card, a SIM card was copied and tested, and then GSM SIM card detection mechanism was discussed. A clone card detection system was developed and verified in Lvliang branch. Results show that the system is able to present alert of suspected clone card. Combined with user＇s call record and stop ＆ boot log, it is basically determined whether the SIM card is copied.
