Application And Implementation Of Lunar Information Sharing Service System Based On G/S Model And JAAS Technology

The face of multi-source and heterogeneous lunar information data, need aprecise, standardized and interoperable information describing the format of the lunarinformation data to manage and storage of heterogeneous data, so in this system, theintroduction of data exchange model based on G/S model and data registration center,use of XML (Extensible Markup Language) to achieve access and management of thelunar information heterogeneous data by separation of metadata and data.At the same time, along with the network popularization and the people rely onthe network, a large amount of data storage has also brought thinking on data security,this system is a platform for the sharing of resources, so the management ofpermissions, the data safety is very important. This system uses Java as thedevelopment language, so we choose JAAS authentication and authentication servicemechanism as system security mechanism, to ensure data security, constructing aninteractive, open, sharing of resources, safety of lunar information sharing servicesystem.In summary, this article use the "Chang E II" data and the related data as the testdata source, use G/S model as the the guiding ideology for storage of heterogeneousdata, and use JAAS authentication and authorization services for the system security,to provide users with a lunar information sharing service platform.In the process of the realizing and applying the lunar information sharing servicesystem, the research contents of this paper made in the following contents:(1)Initially realized the lunar information sharing service system based on G/Smodel and the JAAS technologyIn the guiding ideology of G/S model, initially completed the lunar informationsharing service system application and implementation based on the G/S model andthe JAAS technology.(2)Application study of the JAAS identity authentication and authorization ofservice in lunar information sharing service systemStudy how to use the JAAS authentication mechanism and service authorizationmechanism to realize the identity authentication and authorization system information sharing, and guarantee the data security and security system.(3) Design and application study of the lunar information data managementmodel and application into the systemIn the guiding ideology of G/S model, design the lunar information datamanagement model, research on two aspects; include the heterogeneous datamanagement for efficient access and the data of lunar information data exchange, thestudy of the mechanism of data exchange laid the foundation for the heterogeneousdata access, and use the model to achieve the system.The innovation of this paper and the main research results are as follows:(1) Presents a method of the heterogeneous information data exchange andaccessIn this paper, design management model of the heterogeneous data based on theG/S model, presents a method of the heterogeneous data to realize data exchange anddata access.(2) Presents the JAAS authentication and authorization technology serviceimplementation method in the lunar information sharing service systemThis system is an interactive open system, the data security is particularlyimportant, the security of this system uses JAAS authentication and authorizationtechnology to provide the security for system user authentication and authorizationand operation of the lunar information, but also to do the research and improvementof G/S model in the aspect of safety application.(3) The initial implementation of lunar information sharing service system basedon G/S model and JAAS technologyTaking G/S model as the guiding ideology, combined with JAAS technology tocomplete the initial application and implementation of lunar information sharingservice system based on the G/S model and JAAS technology.
