In this paper, we propose a lightweight mechanism to isolate one or more Android userland instances from a trustworthy and secure entity. This entity controls and manages the Android instances and provides an interface for remote administration and management of the device and its software. Our approach includes several security extensions for secure network access, integrity protection of data on storage devices, and secure access to the touchscreen. Our implementation requires only minimal modification to the software stack of a typical Android-based smartphone, which allows easy porting to other devices when compared to other virtualization techniques. Practical tests show the feasibility of our approach regarding runtime overhead and battery lifetime impact.
