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 viruses and backdoors, there is a great security risk in the 3G smart phone switch-on and off, such as remote control startup, fake shutdown and the like. On the basis of analyzing the risk and switching principle of 3G smart phone on-off and on-off, this dissertation makes a deep research on the detection and control principle of safe on-off and on-off, puts forward the principle of switching on and off key circuit and RF power supply circuit On the access control processing unit, D flip-flop, and gate devices, the phone keys and radio frequency power supply for safe detection and control, and its application in the actual product, the test shows that the method can guarantee the phone’s high security switch Machine, to meet the needs of high-end users.
