Chinese　specification　for　trusted　computing　[7]　has　adopted　a　different　cryptography　scheme　from　specifications　released　by　trusted　computing　group　(TCG)　[1].　Although　the　two　sets　of　specifications　are　functional　compatible,　it　is　hard　for　different　platforms　which　conform　to　different　specifications　to　trust　each　other.　This　paper　proposes　a　trust　model　which　includes　meanings　of　both　behavior　trust　and　identity　trust　to　establish　a　trust　relationship　for　heterogeneous　trusted　computing　architectures.
