In this paper, we are concerned with the detection software faults and tampering of the mobile application as well as the mobile device theft. We want to disable mobile device cryptographically once either of these problems are detected. Basically the device needs to receive a new cryptographic key after each pre-set period of time in order to continue function. The mobile application execution integrity is checked by the authority when deciding whether or not to give out a new key. The detection can be done via a run-time result checking when the device connects to the authority. The authority can also proactively examine whether or not software tampering is happening. This paper will show approaches that each standalone can improve the dependability and security of a mobile application. We will show how these approaches can work together seamlessly to form a stronger scheme.
