Research on Trusted Federated Identity Management and Its Application

It is hard to judge whether one subject is to be trusted where federation identity management only focuses on identity trust achieved by credentials the subject hold. So we propose a behavior trust-based federation identity management mechanism. The trust value was modified according to the subjectpsilas behavior and it will be employed in identity management procedure including identity mapping and identity provision. Then policy-based trust value monitor will adjust the subjectpsilas inter-domain access permissions so as to encourage the subject to act properly.
