3G智能手机开关机安全检测和控制方法

Safety Testing and Control Methods for Power-on/Power-off of 3G Smartphones

由于病毒和后门的存在,3G智能手机开关机存在极大的安全隐患,如远程遥控开机、假关机等。在分析3G智能手机开关机存在的风险和开关机原理的基础上,对安全开关机的检测和控制原理进行了较深入研究,提出了在现有3G智能手机的开关机按键电路及射频供电电路上,接入控制处理单元、D触发器、与门器件等,对手机的按键及射频供电进行安全检测与控制,并将其应用在实际产品中,测试表明该方法能保证手机的高安全开关机,可满足高端用户需求。

Due to the existence of virus and back door,great potential safety problems exist when 3G smartphones power on or power off,such as remote booting and false shutdown.Based on analyzing the risks and the principle of 3G smartphones＇ power-on or power-off,the detection and control principle of 3G smartphones＇ secure power-on or power-off is studied.For the existing power-on/power-off circuit and RF power supply circuit of 3G smartphones,this paper proposes the installation of access control processing unit,D flip-flop,and door devices on the smartphones＇ botton and RF power supply circuits,thus detecting and controlling the security of the smartphones＇ bottons and RF power supply.The test of practical application shows that this method can ensure the smartphones＇ security and meet the demand of high-end customers.
