Research On Unified Authentication Method For SOA Integration Platform

With the continuous development of network and data storage technology innovating ceaselessly, the different operating systems and applications require their own suitable databases, which have brought much difficulty to sharing and exchange of information. Currently, because of the diversity of storage patterns and logical structure for "user-permission" in unified authentication platforms basing on SOA from different manufacturers, there are some problems for difficulties in service integration and defects on the security mechanism.This paper derives a set of unified authentication method and data security mechanism drawing support of Lightweight Directory Access Protocol basing on the educational information supporting platform.Firstly, basing on the analysis for Lightweight Directory Access Protocol, LDAP data structure and data security-related technologies, design the structure and security mechanism for unified authentication and describe briefly directory information tree structure.Secondly, because of the ordering mutiple different services for the inegration platform and exsiting adversity of every service, the paper designs detailedly directory information tree for educational information platform, and projects the integration standards for the heterogeneous system to achieve the service registration for LDAP serverFinally, analysis carefully the security mechanism of unified authentication, and bring out the systemic method basing on directory service certificate authentication to ensure the security of user data.The paper elaborate formalizedly data flow of authentication protocol to ensure the implement for security in maximum.
