| 摘 要： | 基于软件实现的分布式防火墙存在“功能悖论”，基于专用网络处理器的硬件防火墙成本较高、难以普及到网络末端。该文针对以上问题，提出一种基于ARM处理器的嵌入式防火墙设计方案，采用核心板＋扩展板的分板设计，进行U—Boot的定制、嵌入式操作系统的移植、网卡驱动及包过滤引擎的实现。实验结果表明，该防火墙实现成本小、处理速度快，在其硬件平台上可进行后续安全软件的开发。

| Abstract: | It is too expensive for distributed firewall built by NP to dispose them to hosts, so this paper gives a solution of an embedded firewall based on ARM processor to solve the problems. The hardware of embedded firewall is designed into core board and expanded board. It designs U-Boot, migrates the embedded OS, and implements NIC driver and packet filter. Test results show that this firewall is powerful and its security is enhanced with a low cost. |
