摘　　要：为了改善现有密码输入器容易造成密码泄露的缺点,设计了保密型密码输入器。阐述了保密型密码输入器的工作原理,给出具体设计、计算机仿真。经过实验分析和计算机仿真,该电路能够最大限度地保护用户密码并且容易在工程中应用。In order to improve the shortcoming of divulging password for existing password input, the security password input was designed. This paper elaborated the working principle, gave out the design and computer simulation. The circuit can maximally protect the user＇s password and can be easily applied in engineer after the experiment analysis and the computer simulation, and it has high values to popularize.
