嵌入式银行网络安全终端系统的设计

Bank Of Embedded Network Security System For Terminal

本文提出了利用SoC芯片Garfield,设计基于uClinux操作系统和TCP/IP网络的银行自助设备——网络安全终端。从网络安全终端的功能定义与系统方案、网络安全终端的硬件实现原理图与样机制作、uClinux操作系统在Garfield芯片上的移植、网络安全终端各接口驱动以及TCP/IP驱动的编制、终端安全性的实现和终端与相应银行交易系统B/S架构下应用程序的开发等方面论述了系统实现的过程。

The article is to design a bank self-service machine named STOI （Secured Terminal Over Internet）, which makes use of the SoC chip （Garfield） with its own IP right, uClinux and TCP/IP. The main work of the article is： to define the function of the STOI and to design the system solution; to design the schematic document of the STOI with protel; to port the uClinux on Garfield; to code different device drivers of the STOI and the TCP/IP protocol; to accomplish the security of the STOI; to develop the application program under the B/S （Browser/Server） construction with the STOI acting as the Browser and the bank tailing system acting as the server.
