An integrity measurement model for embedded system-based trusted computing platform

Integrity measurement is an important attribute in trusted computing. An integrity measurement model for computing platform is proposed, which aims at providing effective measurement and security protection for the booting of the platform, the loading of the process and the running of the procedure. The trusted platform which is based on embedded system and virtual machine can tolerate untrusted components and needn´t change hardware structure and operating system on the legacy terminal system. On the transferring process of trusted chain of the platform, the shift of control right depends on the results of integrity measurement for every level of the platform. Considering the complexity and variety of every level, different measurement methods are provided for different levels to measure the integrity of components.
