Identity providers (IdPs) need to implement their own FIDO servers that provide interoperability functions with the client in order to support FIDO authentication for users. Many functions, such as signature verification, required for FIDO authentication are common to all IdPs. Hence the challenge is that multiple IdPs must implement these functions independently. We propose a FIDOaaS (FIDO as a service) model in which the IdP uses several decoupled functions related to management of keys for authentication and/or verification of its signatures. We further develop a system that embodies this FIDOaaS model so as to evaluate its performance and trust relationship. We show that our proposed model encompasses a variety of profiles that enable IdPs to flexibly configure FIDO authentication systems according to their security policies.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1627","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1614","bibliographicIssueDates":{"bibliographicIssueDate":"2023-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"64"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00231437","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"created":"2025-01-19T01:31:54.841081+00:00","id":231547,"links":{}}
