Verifiable trust is a desirable property for computing platforms - a user has a fundamental interest in knowing whether a computing platform about to be used behaves as expected. These systems provide verifiable trust by taking immutable snapshots of a platform which digest the complex set of platform components and dependencies into relatively few measurements. This paper introduces a novel extensible integrity management framework that addresses these problems. The framework makes two key contributions: To improve integrity management, they explicitly represent the dependency relation between platform components, which provides the user with more information about the state of the platform. To enable change management, they distinguish reversible changes to measured components from the established irreversible changes.
