Authenticated dictionaries have been primarily studied and used in the context of certificate revocation in public key infrastructure (PKI). This paper presents a novel approach to enabling controlled access to and selective sharing of sensitive user attributes in federated identity management (FIM) by integrating an authenticated dictionary (ADT)-based credential into FIM, while attempting to achieve...
