Google's Android platform has thrived in the smartphone market and has received a considerable amount of attention from mobile developers. Android's open platform encourages development of various applications and delivery systems, but this open source policy weakens dependability against various attacks. In this paper, we apply TOMOYO Linux, which provides MAC-based tools to Android for security enforcement. Because these security enforcement tools run at the kernel level, Android applications do not need to be modified. We also evaluate and analyze patched platforms on an evaluation board. The results show that our platform decreases the performance of the CPU and file operations by as much as 25% while not affecting memory management operations.
