In an ordinary digital certificate system, a user must get an other digital certificate when the user wants to use another secure service that requires another use policy for the client's certificate, because a use policies of a digital certificate are supplied by the issuer of the certificate and its information is embedded into the digital certificate data itself. The special feature of our model is to separate the function of a certification authority into registration authority, certificate issuer and use policy assignment authority of a certificate. We call our model \"Separation of three authorities of certificate.\" In our certification system, the function of a digital certificate is restricted to the certification of a person itself. Subjects of policy assignment of a certificate are individual component of our system. This method makes it possible to assign multiple use policies to one certificate of a person.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"48","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告マルチメディア通信と分散処理（DPS）"}],"bibliographicPageStart":"43","bibliographicIssueDates":{"bibliographicIssueDate":"1998-01-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8(1997-DPS-086)","bibliographicVolumeNumber":"1998"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":35218,"updated":"2025-01-22T14:47:51.825252+00:00","links":{},"created":"2025-01-18T23:03:36.599344+00:00"}
