ABSTRACT
One way to simplify distributed systems security is to have a unified interface for
requesting attributes that security policies need. We explore requirements for getting
attributes, and examine issues of federated data, trust, and confidentiality. Our goal is to
insulate most participants from exactly how and where these attributes are accessed, and
to encourage implementation of each feature at the appropriate level of generality.
