手机控制的蓝牙智能门锁设计与实现

Design and implementation of intelligent bluetooth lock controlled by smart mobile phone

为了解决现有智能门锁安全性差、容易遭到嗅探和远程攻击的问题,研究并设计了一种由智能手机控制的蓝牙智能门锁.该智能门锁以CC2540为主控制器,利用手机带有的蓝牙系统实现无线控制,利用手机闪光灯实现带外安全验证,能有效避免蓝牙嗅探攻击.身份验证码由用户输入,不绑定手机,避免了手机更换或丢失对用户造成的麻烦.实验调试证明,该智能门锁达到了实际运用的要求,具有安全性高、灵活性好、成本低廉的优点.

In order to solve the security problem of existing intelligent door lock which is vulnera- ble to sniffing and remote attacks, research and design of a Bluetooth intelligent door lock controlled by smart mobile phone are made. The intelligent door lock adopts a Bluetooth low energy solution by using the CC2540 uses mobile phones with Bluetooth to implement wireless control, and uses the flash light with verification of safety to effectively avoid the Bluetooth sniffing attack. Authentication input without binding the phone can avoid the trouble induced by the replacement or loss of the phone to the user. The experimental results showed that the smart door lock can meet the requirements of practical application. It has the advantages of high security, good flexibility and low cost.
