Abstract: To solve the logging-on of networked manufacturing integration platform for the service-oriented architecture，a service-oriented intelligent logging-on of networked manufacturing integration platform was proposed.This system uses the intelligent logging-on server,which is centralized in the identity authentication management and distributed in the access authorization management and which also maintains original user administration module independence of the heterogeneous application system in the platform.This paper in detail introduces its basic principle and the realization mechanism,and proposes the application example of the intelligent logging-on of networked manufacturing integration platform.

Key words: networked manufacturing, intelligent logging-on, SSO (single sign on), service integration
