In this paper, the case where the signer is an obligor who is almost crushed by debt is mentioned as an example and we point out that self-compromising the signing private key by the obligor serves as an attack on a creditor. Furthermore, we analyze how it affects on the debt curtailment bargaining between a creditor and an obligor that the obligor has private key self-compromising, and show examples for countermeasure.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1879","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1871","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":"セキュリティ基盤技術"}]},"weko_creator_id":"1"},"created":"2025-01-18T22:45:25.672857+00:00","id":10548,"links":{}}
