Numerous　users　from　diverse　domains　access　information　and　perform　various　operations　in　multi-domain　environments.　These　users　have　complex　permissions　that　increase　the　risk　of　identity　falsification,　unauthorized　access,　and　privacy　breaches　during　cross-domain　interactions.　Consequently,　implementing　an　access　control　architecture　to　prevent　users　from　engaging　in　illicit　activities　is　imperative.　This　paper　proposes　a　novel　blockchain-based　access　control　architecture　for　multi-domain　environments.　By　integrating　the　multi-domain　environment　within　a　federated　chain,　the　architecture　utilizes　Decentralized　Identifiers　(DIDs)　for　user　identification　and　relies　on　public/secret　key　pairs　for　operational　execution.　Verifiable　credentials　are　used　to　authorize　permissions　and　release　resources,　thereby　ensuring　authentication　and　preventing　tampering　and　forgery.　In　addition,　the　architecture　automates　the　authorization　and　access　control　processes　through　smart　contracts,　thereby　eliminating　human　intervention.　Finally,　we　performed　a　simulation　evaluation　of　the　architecture.　The　most　time-consuming　process　had　a　runtime　of　1074　ms,　primarily　attributed　to　interactions　with　the　blockchain.　Concurrent　testing　revealed　that　with　a　concurrency　level　of　2000　demonstrated　that　the　response　times　for　read　and　write　operations　were　maintained　within　1000　ms　and　4600　ms,　respectively.　In　terms　of　storage　efficiency,　except　for　user　registration,　which　incurred　two　gas　charges,　all　the　other　processes　required　only　one　charge.　©　2024
