In　order　to　enhance　the　security　of　computer　terminal,　a　design　of　the　removable　trusted　platform　model　(TPM)　was　presented　which　can　achieve　most　of　function　designed　in　TCG　standard　apart　form　connected　with　computer　by　USB.　A　new　architecture　of　trusted　enhancement　on　general　personal　computer　based　on　removable　TPM　and　the　design　of　its　prototype　was　proposed.　The　architecture　can　accomplish　trusted　boot　of　computer　system　completely　supported　by　removable　TPM　and　broad　the　trusted　mechanism　to　operating　system　and　application.　The　architecture　builds　the　trusted　computing　environment　on　general　personal　computer　without　modify　hardware　platform　which　has　almost　the　same　de-gree　of　security　performance.　It　is　an　attempt　to　establish　the　new　architecture　for　trusted　computing　which　has　more　practicability　compare　to　TPM.
