The Research And Application Of Network Security Of Wireless Mobile Based On Windows CE.NET

With the development of wireless mobile networks,wireless mobile networks based on the information system has been an increasing number of applications in various fields of society,wireless applications are unstoppable trend.PDA-based wireless mobile information system to become the academic research and industry hot spots.Convenience of wireless applications,the wireless information systems become more and more important security issues.Security and stability of information exchange and management decisions of the wireless mobile information system penetration.However,wireless mobile network security technology has become a constraint to its development bottleneck.According to the characteristics of wireless mobile networks,combined with the Wuhan Railway Bureau railway locomotive depot Jianghan fault prediction system practice,research the safety of wireless mobile networks.Wireless network security applications,there are two aspects to consider:First, the security of wireless link,and the other is terminal system(refer to the subject of PDA and portable computer) security.The former mainly includes link transmission of data security,encryption,authentication and anti-denied;the latter is mainly the protection of the safe use of PDA users,including user authentication,data encryption to protect important especially for the SQL Server CE database security protection. From these two aspects of this issue to ensure the safety of wireless applications,a network based on existing GPRS wireless mobile network security model,the model is characterized by the solution from the application layer security issues,make up the existing wireless mobile the lack of network security technology,wireless mobile networks at the same time related to security technology has been optimized.First,the use of a WAP network WPKI systems,to establish the safety of wireless mobile network infrastructure,through systems WPKI achieve WTLS certificates and X.509 certificate issuing and management of security issues so as to provide a basis for settlement.Links for wireless mobile security,has chosen to adopt end-to-PDA Cable VPN server to establish a system to resolve.With this system,the full realization of the PDA through a wireless link to the WAP server,and Internet messaging server security and authentication,such as a series of security needs.In the PDA based on Windows CE.NET terminal system,security issues authentication,data encryption,security program design and other aspects.All of the systems development for the Windows CE.NET operating system are,.NET Compact Framework development platforms,programming using C # language.
