Most　trusted　platform　control　modules　(TPCMs)　act　as　co-processors　to　measure　the　integrity　of　the　input　data　in　response　to　the　requirements.　However,　the　BIOS　is　compromised　the　input　data　and　measuring　result　may　not　be　credible.　The　paper　presents　a　hardware　solution　containing　the　trusted　platform　control　module　with　the　active　measurement　function.　The　TPCM　together　with　the　original　host　computing　system　creates　a　dual　system　which　can　check　the　device　firmware　and　software　to　determine　the　authenticity　and　timeliness　of　input　data　to　ensure　a　reliable　measurement　result.　Theoretical　analysis　of　this　program　shows　that　the　TPCM　active　measurement　can　guarantee　the　authenticity　and　timeliness　of　still　unmeasured　data　to　ensure　reliable　results.
