高安全级电子密码锁的设计与研究

Design and Research of High Level Security Electronic Code Lock

文章研究与设计了一种字母和数字混合的电子密码锁系统。电子锁键盘由16位按键组成,在按下模式键后,可输入由数字、大写字母和小写字母组合的六位密码。输入密码组合高达306次,远高于传统的纯数字密码组合。同时为防止修改密码时出现误操作,增加了验证码功能,在密码连续三次输入错误,密码锁报警。该电子密码锁可在安全级别要求高的密码箱、保险柜等产品上得到应用。

In this paper, we research and design a kind of electronic code lock system using letters and numbers as hybrid encryption. The keyboard of electronic code lock is composed of 16 keys, after press the mode key, a 6 bit password can be input which includes Numbers, capital and small letters. The combination of password ups to 306 times, far higher than the traditional number-only combination. At the same time, to prevent wrong password operation, a function of verification is added, if three times wrong password are continuous input, code lock will raise the alarm. The electronic code lock can be applied in high level security applications and products such as code case and safe box.
