In　current　cloud　computing　platforms,　the　study　of　the　security　of　the　virtual　Machine　in　cloud　computing　has　not　considered　the　cloud　environment,　which　is　a　complex　clustering,　and　it　also　has　not　considered　the　fact　that　the　virtual　Machine　cluster　resides　on　a　single　virtual　Machine.　In　order　to　solve　the　above　problems,　a　method　to　build　a　trusted　virtual　Machine　groups　based　on　the　particle　wave　equation　is　proposed　to　build　a　trusted　virtual　Machine　group.　Compared　with　the　traditional　security　policy　for　a　single　virtual　Machine,　the　measurement　parameters　of　our　method　can　be　formulated　according　to　different　environments,　it　has　a　better　environmental　adaptability,　and　by　constructing　a　virtual　Machine　cluster　it　can　effectively　reduce　the　security　threats　to　virtual　Machines.　Copyright　©　2018　Inderscience　Enterprises　Ltd.
