(Resource Public Key

adoption of Internet routing security technologies poses a social dilemna where the cost exceeds the benefits of adoption for “rational” players, but the benefits exceed the cost for the whole

However the actual RPKI adoption has been gradually increasing. The authors previously proposed a model that incorporate bounded rationality and altriusm and demonstrated the possibility of spontaneous adoption with this model. In this paper, we verify the suitability of the model with actual adoption data, specifically for each RIR adoption history. We found some discrepancies between the actual data and the model using fixed parameters, hence we propose a time-varying parameter model to improve the fit with historic data.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2026-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"71","bibliographicVolumeNumber":"2026-IOT-72"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"id":2007448,"updated":"2026-02-16T07:52:23.851965+00:00","links":{}}
