A Usage Control Platform Based on Rule Templates and Authorization Credentials

The popularization of PaaS environments presents challenges to traditional authorization models for controlling resource usage. This article describes a hybrid authorization model suitable for PaaS environments, using rule templates, authorization credentials and local derivation of individual policies. In addition, we present the usage control mechanisms that eliminate the main disadvantages of policy models based on provisioning and outsourcing. The work also shows the technical details of the implementation of a prototype with its performance evaluation results.
