摘要
针对现实生活中人们输入重要密码时因被窥视而发生密码被盗现象,本文以输入按键和数码随机动态显示的形式,给出了一个智能型密码输入器的设计实现方法。利用伪随机数发生器原理,以微控制器PIC16F877为核心,配合按键和数码显示实现随机数的产生,对0-9十个数码位置的随机排列,并实现输入和显示相一致的效果。
Due to the phenomenon of important passwords stolen when people input their passwords,thin paper discussed intelligent design method by pressing the buttons with the digital keys in dynamic random display.By use of principle of pseudo-random number generator,based on PIC16F877 Micro-controller,with buttons and digital display of random numbers generated from 0 - 9 in random order,get the consistent results of input and display.
