Credential Chain Discovery in RT~T Trust Management Language

摘要

The goal of this paper is to explore the potential of Role based Trust management language RTT as a means for specifying security policies and using credentials to ensure that confidential resources are not being granted to unauthorized users. The paper describes formally the syntax and semantics of the language and defines RTT credential graphs and credential chains as a means for answering security queries. Backward and forward search algorithms to build a credential chain are given.
