In our proposed system, each authentication server has two functions, issuance and verification of authentication tickets, while each user carries his/her authentication data, issued by his/her local authentication server, using authentication tickets. Each authentication server transmits its public key to each other beforehand, so that these public keys can be used for verifying the authentication tickets issued by other servers. Thereby, any authentication servers can authenticate any users locally, without any inquiry to the other servers. By the proposed system, we can provide a large scale distributed authentication system which satisfies the nature of a ubiquitous network, “Anytime, Anywhere, with Anyone”.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"52","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"47","bibliographicIssueDates":{"bibliographicIssueDate":"2006-07-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"80(2006-QAI-020)","bibliographicVolumeNumber":"2006"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T09:14:25.070157+00:00","created":"2025-01-18T23:12:30.667265+00:00","links":{},"id":46906}
