A Trusted Domain-based Approach for Authorization and Delegation on Mobile Distributed System

摘要

In this paper, we propose an architecture for handling distributed security and trust on mobile distributed systems. We outline a method for access control across domains that handle complex trust relationships. We have developed a flexible representation of trust information, which can model permissions and delegations. Moreover, we are currently working on modeling obligations, entitlements, and prohibitions as well. By using examples, this paper finally explains the internal working of our system and the trust information that flows within it.
