Although, previous works in the literature already addresses the question of anonymity in packet networks, these solutions usually cannot apply to unstable networks, where the network topology changes dynamically. Valkyrie is based multiple encryption scheme and routing technique that is adopted by Onion Routing scheme. Because of that, Valkyrie can transmit messages on (stable) network anonymously. In addition, Valkyrie has two new onions: Alternate Onion and Back Track Onion. These two onions can bypass disconnection on unstable network. Consequently, Valkyrie is anonymous routing scheme which can run on unstable network.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2035","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2025","bibliographicIssueDates":{"bibliographicIssueDate":"2005-08-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"46"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"ネットワークセキュリティ"}]},"weko_creator_id":"1"}}
