Efficient Attribute Management in a Federated Identity Management Infrastructure

Federated Identity Management technologies are exploited for user authentication in a number of network services but their ease of use and efficient attribute handling are still open issues. We present the STORK 2.0 pan-European infrastructure which supports attribute management, and we propose a data structure, named Attribute Object Identifier (AOI), and its integration into the STORK 2.0 architecture to allow faster access to attributes.
