The　emergence　of　new　computing　paradigms　such　as　cloud　computing,　the　Internet　of　Things,　and　the　mobile　Internet　has　increased　the　need　for　inter-domain　access　and　data　sharing,　while　at　present　the　＇centralized＇　traditional　access　control　technology　have　showed　opaque　of　access　control　policy　execution,　inflexibility　of　dynamic　data　management,　low-autonomy　of　resource　owners,　these　shortcomings　make　it　difficult　to　satisfy　the　requirements　of　access　control　for　new　computing　paradigms　with　massive,　dynamic,　and　distributed　features,　an　inter-domain　access　control　model　based　on　ABAC　model　and　blockchain　interaction　is　proposed.　This　paper　introduces　the　technical　principle,　characteristics　and　research　status　of　the　ABAC　model　and　blockchain,　elaborates　the　model　framework,　defines　the　definition　of　the　ABAC　model.　At　the　same　time,　the　smart　contract　in　the　model　is　described　in　detail,　and　the　application　in　the　specific　scenario　and　the　specific　access　control　flow　are　given.　Finally,　compared　with　the　existing　research　solution,　this　model　can　provide　standardized　security,　convenient,　autonomous,　and　fine-grained　access　control　for　inter-domain　access.　©　Copyright　2021,　Institute　of　Software,　the　Chinese　Academy　of　Sciences.　All　rights　reserved.
