Research Of Cloud Polymerization Technology Based On Identity Infoermation

The problem of applications integration is always letting enterprises put focus on it. Now, with the cloud computing continue to influence our production and living, more and more enterprises and individuals have to use the services or applications. Like traditional applications, the existing cloud applications are independent and decentralized. And these become the problem. Like users have to use to access each application separately, and separately memory and management their login credentials. Thus, these caused some impaction on the user’s productivity and application experiences. On the other hand, it is also challenge the company management, because of the applications’ distribution and independence. Thus, the traditional application integration issues in the context of integration again placed in front of people,but this time,it is cloud computing.For solving the above problems, this thesis carried a systematic study on cloud application integration. And give a specific practice on cloud application integration with local applications. Firstly, we analyze the related issues of cloud application integration and then give the organic integration target of cloud applications: cloud polymerization. Secondly this thesis analyzes the authentication problems of cloud application integrate with the local application and summed up the deficiencies of the existing single sign-on technology to solve the above problem. To solve this problem, this thesis proposes a method called: "proxy authentication method based on cloud application". Finally, in order to put the method into practice, we build Hunan Finance and Economics College portal system. These theses also give the detail process of designing and coding to implement the system and carry out the related tests.During the implementation process of the portal system, we detailed design and implement the process of cloud applications and local applications integrate in presentation layer and the business layer, unified identity authentication, permissions authentication and other functions. We also give the solutions of data and permissions synchronization problem of the portal system during the system building time. We divided the implementation process into some parts like: requirements analysis, system design, function realization, showing the effect of system and associated test. Throughout the process, we have adopted the idea of software engineering.The key technologies of the cloud application integration, which this thesis researched and practiced, have a good role in companies’ information construction. And these technologies received good results in the actual system application. So, the achievements can promote the popularity of clouds applications to the enterprises and individuals.
