The invention discloses a function encryption safety lock and a control method thereof. The function encryption safety lock comprises a lock body, a spring bolt seat, a spring bolt, a keyboard and a display screen. A controller, a battery and a buzzer are arranged in the lock body; the motor is used for driving the spring bolt to linearly reciprocate; a mathematical function for encryption and a domain of definition thereof are arranged in the controller; and the controller is used for randomly generating an independent variable, displaying the independent variable on the display screen, comparing a password input by the keyboard with the dependent variable, and controlling the rotation of the motor according to a comparison result. In actual use, the independent variables generated every time are different, and the passwords generated every time the lock is unlocked are also different; that is, if others peep the password input by the user on the keyboard, unlocking cannot be completed next time. Even if the value of the independent variable displayed on the display terminal and the password input by the keyboard are peeped, the function for encryption cannot be deduced reversely.
本发明公开了一种函数加密的安全锁及其控制方法所述函数加密的安全锁包括锁体、锁舌座、锁舌、键盘、以及显示屏；锁体内设置有控制器、电池、以及蜂鸣器；所述电机用于驱动锁舌直线往复移动；所述控制器中设置有用于加密的数学函数及其定义域；控制器用于随机生成自变量并显示在显示屏上、将键盘输入的密码与应变量进行比较，并且根据比较结果控制电机的转动。实际使用时，每次生成的自变量是不同的，每次开锁时的密码也是不同；即他人偷窥到用户在键盘上输入的密码，下次也无法完成解锁。即使显示终端上显示的自变量的值和键盘输入的密码都被偷窥到，也无法反推出用于加密的函数。
