摘　　要：通过分析CAN总线通信系统和基于Wi-Fi后门的嵌入式系统,对可能存在的信息安全问题进行研究。采用8051型MCU作为嵌入式系统中CAN节点的控制器,结合Delphi环境下的图形界面开发、步进电机控制,搭建了CAN总线通信系统模型,采用Wi-Fi"透传"技术为系统模型添加后门控制接口,并通过后台控制器实现对系统的监控,从而真实地反映结合了Wi-Fi后门控制接口的CAN总线通信系统的运行状态。With the analysis of CAN Bus communication system, Wi-Fi based backdoor embedded system, and the investigation into the potential information security problem, this article provides a solution of model design which applies 8051MCU as CAN controller to build up a CAN bus communication system with the combination of Delphi-based GUI and Stepping Motor control. Wi-Fi communication technology is adopted as backdoor interface and the system is monitored with backdoor controller. As a result, the model truly reflects the operation status of Wi-Fi interface backdoor-based CAN bus communication system.
