摘要
针对增强单片机系统安全性这一课题,提出了一种双机校验方法,即应用两块异构的单片机构成主从系统,通过软件模拟I2C总线进行互连通信,在主、从机端分别执行校验,以达到增强安全性的目的。
A way to enhance the security of microeontroller system through an improved double check method is introduced. In this method, the master and slave microcontrollers communicate with each other through I^2C bus which is simulated in software way. The check process will be carried out at both sides. Based on the check results, the security status of system will be evaluated.
