Research And Implementation Of Key Technology In Security Test For Windows Os Based On PDA

Windows CE is an open, scalable, 32-bit embedded operating system that is designed to meet the needs of a broad range of embedded devices, from enterprise tools to consumer products. It has a complete OS feature set and comprehensive development tools. With user interface similar to Windows series for PC ,Windows CE is easy to most end-users.This article starts from the research and study of the kernel of Windows CE,and analyses the device managing strategy and the architecture of its device drivers, then researches the architecture of USB and the loading/unloading process of USB device drivers especially.The technology of USB function client drivers switch based on Windows CE is achieved by the study of USB device drivers. Then, by the research of HID model, this thesis realizes the design of semulating USB keyboard driver.After researching the technology of USB function client driver switch and semulating USB keyboard driver,We design a prototype program called Security Testing running on Windows Mobile oprating system.On the base of simulating the scan code of keyboard,this program possess security testing database for Windows desktop OS and the function of document management.In this thesis the design thought of security testing for Windows opration systems based on PDA is proposed, and it is also a new program design of USB function client driver switching based on Windows CE and HID USB keyboard driver semulating. The program which is running on PDA is very convenient to the deployment of security testing, and provides a new solution of popularizing srcurity testing into application.
