In the electronic signature technology, it is assumed that only the person in question can use a private key of each entity. However, such assumption might not consist of various factors such as the theft of a private key and the progress of various technologies. In such a situation, the attacker can easily forge an electronic signature of another entity. Then, we propose ``Alibi establishment mechanism for electronic signatures''. We can distinguish valid signature and forged one with the signature log file, which is stored safely in a tamper resistant module. We also propose two technologies, ``Hysteresis signature'' and ``Signature history intercrossing'' to be strengthened the evidence of the signature log file.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2393","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2381","bibliographicIssueDates":{"bibliographicIssueDate":"2002-08-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"43"}]},"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":"電子社会"}]},"weko_creator_id":"1"},"created":"2025-01-18T22:46:06.807248+00:00","id":11499,"links":{}}
