嵌入式WEB服务器及其安全机制研究

为了能通过网络访问远程设备,构建了一个嵌入式WEB服务器;在基于ARM9微处理器的嵌入式服务器上,移植并安装了U-BOOT系统、嵌入式LINUX操作系统和BOA系统,在系统中,远程用户通过浏览器访问服务器,服务器再通过CGI对设备驱动程序的调用来实现系统对设备的访问,为了弥补BOA服务器安全性的不足,利用CGI实现了COOKIE机制,来确保系统的安全;结果表明本系统是可实现的,且有较高的安全性保障.

Research on Embedded WEB Server and Its Security Mechanism

To access remote device by network, an embedded WEB server was constructed. The U--BOOT system, embedded LINUX system, and BOA system were transplanted and setup on the embedded server which based on ARM9 microprocessor. In the system the remote user accessed server by Internet Explorer, then the server utilized CGI calling the driver of device to access the hardware. Meanwhile, to compensate the shortcoming of the security of BOA server, the COOKIE mechanism was realized to ensure the security of system by using CGI. The result demonstrated that the system is realizable with higher security guarantee.
