When considering applications of ABC to mobility services such as Park & Charge, users should delegate the minimum necessary attributes supported by their credentials to their cars. However, existing ABCs (including delegatable ones) do not support such functionality. In this paper, we introduce ABC with credential redaction (ABC-CR), which allows users to use credentials that support some attributes to create credentials supporting a part of the attributes. We propose a construction based on Hébant and Pointcheval's traceable ABC system and provide experimental results.\n","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"554","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":"547","bibliographicIssueDates":{"bibliographicIssueDate":"2023-10-23","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":228688,"links":{}}
