- W3004931365 abstract "Service-oriented architectures implemented by web services technologies provide standardized protocols for communicating and sharing information across organizational boundaries. The access control of shared services becomes an essential requirement for a secure federation of services. The identity federation provides part of the response by allowing users to authenticate once in an organization and to access the services of others with its authorization information or attributes. However, in a federation, the organizations may have different access control models and authorization attributes with different or even incompatible semantics. Interoperability between the access control models becomes crucial to the federation of services. Existing federated access control solutions are based on the single sign-on with common authorization attributes or the identity mapping that is not scalable in a service-oriented environment. In this paper, we propose a cross-organizational access control method for the federation of services protected by heterogeneous access control models. Our method is based on a new federation architecture that responds to the heterogeneity of authorization attributes via independent attributes introduced at the federation level." @default.
