Role Based Access Control For Android ( RBACA )

Android as an open platform dominates the booming mobile market. However its permission mechanism is inflexible and often results in over-privileged applications. This in turn creates severe security issues. In this paper, we propose a Role-Based Access Control for Android (RBACA) framework to address this problem. We show how the widely used Role-Based Access Control (RBAC) approach can be applied to Android mobile systems in order to mitigate the security risks caused by over-privileged applications. We explain how single users as well as large corporations can make use of RBACA. An initial prototype of RBACA has been implemented and its functionality can be
