Any　endpoint　with　network　connection　may　be　our　workbench　as　new　computing　models　like　cloud　computing　arise.　We＇ve　designed　a　protocol　to　establish　the　user＇s　trust　in　public　endpoints　covering　hardware,　firmware　as　well　as　software　components.　Three　parties　are　involved　for　trust　establishment:　the　user　with　a　chip　(MTPCM)　to　actively　measure　the　platform;　the　endpoint　owners　who　offer　the　platforms　allowing　the　mechanism　of　the　user＇s　active　action;　and　the　remote　service　providers　with　the　functions　of　verification　and　feedback.　The　protocol　is　implemented　based　on　a　novel　architecture.　©　2010　IEEE.
