Our implementation is aimed at estimating the possibility of employing TCG-based trusted computing mechanisms, such as verifying the code-integrity of executables and libraries at load-time and remote attestation, in mobile devices. Considering the restrained resource in mobile device, the experimentation shows promising results, thereby enabling these mechanisms to be used as a basic building block for a more secured mobile service. To this end, we add a new feature of integrity measurement and verification to Wombat Linux kernel and Iguana embedded OS. We also implement attestation agents, Privacy CA, and TCG Software Stack.
