摘要
随着车载信息系统的应用推广,车载网络与移动通信网络互联的安全性问题日益突出。本文论述了一种支持车载信息系统的网络防火墙的设计过程,介绍了防火墙系统的软硬件环境以及该防火墙所要实现的功能和开发步骤,最后重点对该防火墙系统数据捕获和数据分析处理两大模块进行说明,并在嵌入式Linux环境下用C语言实现了此防火墙,验证了其有效性和正确性。
With the increasingly widespread application of on-vehicle information system, the security between on-vehicle network and mobile communication network has become increasingly prominent. This paper presents the design process of a kind of firewall based on MOST which is an on-vehicle network standard. It presents how to build the firewall, especially, the Data capture module and data analysis module is described. Finally, the methods described in the paper have all been validated in embedded Linux de- velopment platform.
