基于Skyeye和μClinux的轻量级安全Web服务器的设计与实现

Design and Implementation of Lightweight Secure Web Server Based on Skyeye and μClinux

随着嵌入式系统的发展,嵌入式Internet的应用越来越广泛。他在方便了用户和嵌入式系统交互的同时,也对安全性提出了更高的要求。针对以往的嵌入式Web服务器采用的基本认证方式具有安全性脆弱的缺点,讨论了认证在嵌入式Web服务器中的实现,并开发了一个安全的轻量级Web服务器,取名为Pandowdy。系统采用了Skyeye这一硬件模拟平台作为开发平台,具有开发效率高,易于调试等优点。最后阐述了基于μClinux的应用开发移植的一般过程。

Along with the rapid development of embedded systems, the usage of embedded Internet becomes more widely. However, security of embedded Internet becomes a key issue of embedded systems. In order to overcome the shortcoming of basic authorization, which is widely used in traditional embedded systems, the paper uses a more secure authorization way of digest authorization and develops a lightweight secure Web server named Pandowdy. Instead of using actual hardware, the paper uses Skyeye, a hardware simu- lation as system development platform. At last, the paper summarizes some processes of porting embedded systems from host systems.
