摘要：

Productive　information　system　has　high-level　security　requirements,　but　Trusted　Computing　Group＇s　solution　of　trust　chain　isn＇t　competent.　After　analysis　and　comparison　of　two　different　trust　transfer　ways,　a　new　trust　chain　scheme　was　designed　and　its　architecture　was　shown.　With　independent　TPCM　as　a　trust　root,　this　scheme　combined　the　advantages　of　linear　and　radial　transfer.　So　that　stronger　cryptographic　algorithm　could　be　adopted　by　TPCM　and　applications＇　trust　attenuation　decreased　a　lot.　This　scheme　was　described　formally　by　6　linear　temporal　logic　rules.　It　was　proved　that　based　on　these　rules,　this　scheme　could　transfer　trust　from　trust　root　to　applications.　Meanwhile,　it　could　actively　report　and　handle　exceptions　in　trust　chain　building　and　system　running.　Conclusion　and　future　work　were　given　at　the　end　of　this　manuscript.　©　2012　Universitas　Ahmad　Dahlan.
