As　the　new　computing　service　pattern　of　cloud　computing　develops　rapidly,　the　security　problem　of　cloud　computing　has　become　a　hot　research　topic.　Before　the　user　passes　important　data　or　computing　task　to　the　cloud,　the　user　of　the　cloud　may　want　to　verify　the　trusted　status　of　the　platform　which　actually　carries　out　the　computing　task　in　the　cloud.　And　the　remote　attestation　mechanism　in　Trusted　Computing　is　suited　for　the　cloud　user＇s　verification　need.　In　this　paper,　the　property-based　remote　attestation　mechanism　in　Trusted　Computing　is　imported　into　clouding　computing,　and　a　property-based　remote　attestation　method　oriented　to　cloud　computing　is　designed　based　on　the　characteristics　of　cloud　computing.　In　this　method,　through　the　attestation　proxy,　the　remote　attestation　of　the　computing　platform＇s　security　property　is　realized　without　disclosing　the　platform＇s　configuration,　and　users　can　validate　the　security　property　of　the　actual　computing　platform　in　the　virtual　cloud　computing　environment.　©　2011　IEEE.
