Abstract
Cloud computing presents new security challenges to control access to information in cloud services. This article describes an authorization model suitable for cloud computing that supports hierarchical role-based access control, path-based object hierarchies, and federation. The authors also present an authorization system architecture for implementing the model. In particular, they provide some technical implementation details, together with performance results from the prototype. They also describe security, privacy, and trust management aspects for the authorization system.
