In　cloud　storage　scenarios,　data　security　has　received　considerably　more　attention　than　before.　To　ensure　the　reliability　and　availability　of　outsourced　data　and　improve　disaster　resilience　and　data　recovery　ability,　important　data　files　possessed　by　users　must　be　stored　on　multiple　cloud　service　providers　(CSPs).　However,　we　know　that　CSP　is　invariably　not　reliable.　In　this　situation,　to　verify　the　integrity　of　replica　files　stored　by　users　on　multiple　CSPs　simultaneously,　a　new　dynamic　multiple-replica　provable　data　possession　(DMR-PDP)　scheme　is　proposed.　In　addition,　due　to　the　importance　of　the　tag　set,　we　utilize　vector　dot　products　instead　of　using　the　modular　power　calculation　in　the　traditional　PDP　scheme,　which　greatly　reduces　the　calculation　time　and　storage　space　usage.　Moreover,　a　novel　dynamic　data　structure,　the　divided　address-version　mapping　table　(DAVMT),　is　presented　and　used　to　solve　the　problem　of　data　dynamic　operation.　A　practical　experiment　validates　the　effectiveness　of　our　proposed　scheme　in　the　end.
