基于单片机的金库门电子密码锁系统设计

The Design of Cryptographic Lock for Treasure Reserve Based on SCM

针对金库门高保密性与安全性的要求,设计了一种新型金库门电子密码锁,能预防密码泄露,增加金库安全性。系统由金库门密码锁控制器和密码生成器组成,密码生成器提供开锁密码,密码重复概率低于1/1 000 000。当输入开锁密码错误超过三次则启动报警系统。论文介绍金库门电子密码锁系统硬件和软件的实现思路,给出了硬件原理图和程序流程图。

This paper designs a cryptographic lock system for the high secret and security of treasure reserve.It can prevent the password from letting out and enhance the security of treasure reserve.This system is composed by the cryptographic lock controller and password maker.The password is provided by the password maker and different every time with the repeated percentage lower than million percent.When the password is input wrongly more than three times,the cryptographic lock will alarm.This paper also gives the thought of hardware and software design of this cryptographic lock,and shows its hardware schematic diagram and software flow chart.
