To avoid modifications of Web services and browsers, this system uses proxies. Moreover, we implemented the protocol that managed the blacklist on the server side. The experimental results show that each protocol is available in practical time.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"71","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2011 論文集"}],"bibliographicPageStart":"66","bibliographicIssueDates":{"bibliographicIssueDate":"2011-10-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2011"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":77907,"links":{}}
