In　the　distributed　environment,　one　important　security　issue　is　how　to　apply　further　security　control　to　the　object　that　is　released　to　other　terminals.　The　appearance　of　trusted　computing　technology　has　provided　an　effective　solution　for　this　issue　in　the　distributed　environment.　At　the　same　time,　through　combining　trusted　computing　technology　with　the　strong　isolation　and　sharing　characteristic　provided　by　virtual　machine　technology　has　further　increased　the　security　and　the　flexibility　of　distributed　access　control.　Therefore,　this　paper　uses　trusted　computing　technology　to　improve　the　security　of　the　terminal　in　carrying　out　the　distributed　access　control,　designs　a　trusted　terminal　architecture　that　bases　on　the　trusted　computing　technology　and　the　virtual　machine　technology　as　well　as　a　enhanced　mode　that　suits　in　distributed　access　control,　and　on　this　basis,　analyzes　the　security　of　system　design.　©2009　IEEE.
