Abstract: Based on deep analysis of integrity measurement,in order to solve the problem of integrity measurement architecture of trusted computing,which is too complex,hard to be extended and does not reflect trusted behavior,this paper introduces the concept of trust,makes use of trust measurement scheme,accords to the requirement and goal of trust measurement,and proposes requirement-driven multi-goal measurement object tree(MOT) model and corresponding trust measurement model(TMM).According to the contrast analysis between TMM and TCG's integrity management model(IMM),the TMM is more practical because it can provide composite trust measurement result and easily be extended.
