とスマートフォンの 2 端末を利用する脳内署名方式のユーザインターフェースを検討した．脳内署名方式では署名生成の際に署名者である人間の脳内で one time pad による文字どうしの加算処理を行う必要があり，実現可能性が懸念されていた．そこで，文字どうしの加算を容易に行うために，加算表を導入することによって脳内処理を大幅に軽減した．その後，設計したインターフェースを実装しユーザ実験により評価を行った．その結果，客観評価では5名すべての実験協力者が正確に署名生成することが可能であり，主観評価では課される認知負荷は高いが許容されることが示唆された．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"73","bibliographicVolumeNumber":"2024-CSEC-106"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":237279,"updated":"2025-01-19T08:56:05.880877+00:00","links":{},"created":"2025-01-19T01:39:49.256347+00:00"}
