基于单片机的多进制动态密码在通讯中设计

Design of multi system dynamic password based on single chip microcomputer in communication

基于目前对通讯过程中信息传递保密性、安全性和灵活的要求。通过利用单片机中的定时器/计数器产生的PWM信号,从而采用多进制数据传输的方法并把这一传输方式应用与通讯过程中。主机与从机采用单总线、问答式且双向验证的方法来产生动态密码,大大提高了信息在传递过程中的安全保密性。

Based on the current communication process of information transmission security, security and flexible requirements. By using the PWM signal generated by the timer/counter in the single chip microcomputer, the method of multi band data trans-mission is adopted, and the transmission mode is applied and the communication process is adopted. The host and slave use a single bus, Q&A and two-way authentication method to generate dynamic password, which greatly improves the security and confidentiality of information in the process of delivery.
