Remote　attestation　is　the　key　technology　of　trusted　cloud　computing.　The　existed　remote　attestation　schemes　are　not　sufficient　to　consider　the　trusted　measurement　of　the　running　virtual　computing　node.　In　this　study,　by　the　analysis　and　comparison　of　existing　remote　attestation　schemes,　we　propose　a　trusted　measurement　of　the　running　virtual　computing　node　and　a　threshold　remote　attestation　scheme　based　on　the　trusted　measurement　results.　By　RO　security　analysis　and　a　simulation,　we　verify　the　security　and　efficiency　of　the　scheme.　The　trusted　measurement　of　the　running　platform　is　mainly　based　on　the　trusted　measurement　of　the　programs　running　on　the　platform　and　a　total　trust　value　of　the　platform　by　an　algorithm.　The　Threshold　remote　attestation　for　trusted　measurement　of　the　running　platform　is　based　on　K-CCA　problem.　©　2013　Asian　Network　for　Scientific　Information.
