Authorization, which allows third parties to access information managed by an organization, is a method of achieving limited access to information. Initially, to manage resources closed to an organization and to control access, with the spread of the Internet, they have come to be used to control access to resources beyond the network and to authorize access to resources managed by different organizations. Centralized resource management with access control and authorization had been the mainstream due to user convenience, ease of management, and the ability to utilize data through information aggregation. In recent years, however, the SPOF problem caused by centralization and user privacy issues caused by the centralization of information have led to a demand for decentralized management. In addition, with the development of IoT, resources themselves are scattered over the network, and decentralization of resource management and connection to resources is becoming increasingly necessary. The distributed ledger technology is the backbone of distributed management. Since multiple systems are linked and always synchronized, even if one system stops or fails, the impact on the operation of the entire system can be minimized, making it easier to solve the problems of SPOFs and unipolar concentration of information. Considering these current situations, this paper summarizes the latest trends in distributed authorization and access control mechanisms, their technologies, and future issues.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"446","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2023論文集"}],"bibliographicPageStart":"439","bibliographicIssueDates":{"bibliographicIssueDate":"2023-10-23","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:27:48.955802+00:00","updated":"2025-01-19T11:46:03.181373+00:00","id":228674}
