摘要：

To　solve　the　problem　that　traditional　network　cannot　satisfy　the　development　of　future　network,　network　slice　(NS)　technology　was　introduced.　A　conception　of　software　defined　trust　(SDT)　based　on　software　defined　network　(SDN)　and　trusted　computing　was　proposed　in　this　paper.　In　view　of　OpenvSwitch　(OVS)　and　virtual　tenant　network　(VTN)　of　OpenDaylight,　a　model　of　NS　based　SDT　was　put　forward.　When　a　tenant　requests　the　resource,　it　can　gather　the　trust　state　of　switches　and　distribute　the　trusted　NS　for　different　demands　accordingly.　When　the　NS　is　untrusted　in　using,　it　can　make　rectifications　by　OVS　retroversion　and　flow　table　recovery.　After　experimental　verification,　this　method　improves　the　resource　utilization　and　the　efficiency　of　NS　recovery　while　guaranteeing　its　trust　state.　©　2019,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
