Secure Policy-based Device-to-device Offloading for Mobile Applications

Mobile application offloading, with the purpose of extending battery lifetime and increasing performance has been intensively discussed recently, resulting in various different solutions: mobile device clones operated as virtual machines in the cloud, simultaneously running applications on the mobile device and on a distant server, as well as flexible solutions dynamically acquiring other mobile devices' resources in the user's surrounding. Existing solutions have gaps in the fields of data security and application security. These gaps can be closed by integrating data usage policies, as well as application-flow policies. In this paper, we propose and evaluate a novel approach of integrating XACML into existing mobile application offloading-frameworks. Data owners remain in full control of their data, still, technologies like device-to-device offloading can be used.
