Dynamic　migration　of　virtual　machine　(VM)　is　the　main　feature　of　the　cloud　environment,　and　trusted　computing　is　one　of　the　core　technologies　to　solve　the　security　problems　of　the　cloud　environment.　Aiming　at　the　security　problem　of　VM　and　virtual　trusted　root　(VTR)　migration　in　the　cloud　environment,　an　active　dynamic　trusted　migration　scheme　built　upon　the　Chinese　active　immune　trusted　computing　(AITC)　is　investigated　in　this　paper,　where　migration　architecture　and　protocol　are　included.　To　validate　the　effectiveness　of　the　scheme,　experiments　are　carried　out　and　promising　performance　is　shown　in　comprehensive　experiment　results.　©　2020,　Springer　Nature　Singapore　Pte　Ltd.
