Research And Implementation Of Identity Management Patterns Based On J2EE

Identity management is a prominent issue of current enterprise applications, but also a hotpot of the construction of distributed resources system now. Although identity management technologies and standards are maturing, and many organizations and corporations have put forward a number of identity management solutions, but many problems still exist in the specific application and implementation. A major problem is that the different security architecture and infrastructure. Nowadays,a lot of enterprise application systems are designed and developed based on J2EE platform. Therefore, Research J2EE-based identity management problems have some theories guiding significance and practical application of significance.The paper studied a lot of today's identity management related technologies and standards, analyzed the characteristics of the J2EE application and its security system , used some design patterns such as builder patterns,proxy patterns and factory patterns, combined SAML standards and raised the following patterns: assertion builder pattems,SSO delegator patterns and credential tokenizer patterns. These patterns not only improved the compatibility and portability of enterprise identity management but also reduced system design and development complexity effectively.In the end of the paper,we succefully implemented the patterns in the Online Service Platform Based Linkman Management system, analyzed the actual effect and pointed out the research content and direction of the paper to be expand.
