METHOD AND APPARATUS FOR PROVIDING AUTHENTICATION BASED ON AGGREGATED ATTRIBUTE IN FEDERATED IDENTITY MANAGEMENT

摘要

Disclosed herein are a method and apparatus for providing authentication based on aggregated attributes in federated identity management. A federated identity system includes a user terminal, a server of a service provider, a first identity provision server, and a second identity provision server. The first identity provision server and the second identity provision server respectively provide attributes of a user's identity. The user terminal determines whether providing service to the user terminal is permissible, using the aggregated attributes. When it is determined that provision of the service is permissible, the user terminal acquires the service from the server of the service provider.
