A Secure Model Research Of Mobil OA Based On PKI And Application For China Customs

With the rapid increasement of network attack methods and attack tools,The problem of network security management is confronted with serious threatPeople have proposed many network secure medels so that they can adapt to the security management requirements.The existing secure models either adapt to to centralized enviroment or distributed enviroment.But the ones adapted to distributed enviroment can't satisfy with the mobile OA secure requirements based on wire and wireless network communication. Having analysed the existing secure models and considered the requirements of mobile OA, This article proposes a secure model of mobile OA focus on the security of mobile OA, and applied it into the customs mobile OA. The main work is as following:1) Analyses security in mobile OA models. Having acquired the mobile OA security requirement, we designs and constructs mobile OA secure model MOASM based on PKI.lt can safely performs data encryption, authentication, access control, data entirely validation and undeniability by using MOASM .2) Describes technologies such as VPN and CDMA1X-VPDN that can be applied into mobile OA in detail. According to the secure model framework of mobile OA based on PKI, this article constructs a mobile OA secure architecture based on WVPDN.According to the framework, Mobile users can connect the local network seamless and safely, and the framework supports many kinds of encryption methods.3) Based on mobile OA model MOASM, and the architecture referred to in this article, we introduce the design and implement of the customs mobile OA System. We describe the design of the Internet connection service, the design of the application service platform, and the choice of application development platform, function design, and data design. We also introduce the user identity authentication, access right control, and network security isolation device and perform the system successfully.The software development and the performance of the realized customs mobile OA system shows that: the mobile OA secure model MOASM based on PKI can achieve confidentiality, integrity, availability, undeniability, It can satisfy all the requirements in mobile OA.
