is a routing protocol to guarantee the validity of routing information on the Internet by utilizing digital signatures. However, BGPsec is impractical due to the heavy size of a  memory storage caused by digital signatures. In this paper, we present APVAS+, which is able to aggregate digital signatures on individual routes into a single short signature and thereby the size of a memory storage can become independent of network configurations. Moreover, we show a prototype implementation of APVAS+ by extending a router software called BIRD and then conduct experiments on the full route information, i.e., about 800,000 routes.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"174","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2020論文集"}],"bibliographicPageStart":"167","bibliographicIssueDates":{"bibliographicIssueDate":"2020-10-19","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
