Our results include error analysis techniques for public-key encryption schemes in a computational model in which artificial noise is added to the matrix-vector product, confidentiality computation in which the algebraic properties of public-key cryptography are exploited to protect the privacy of the participant’s data, and a commitment scheme, an electronic envelope, based on the model, and showed its wide range of applications. Furthermore, we developed a technique for analyzing the computational resources of a highly efficient secure computation protocol that achieves a higher level of security and communicates only once.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2017年度～2021年度科学研究費補助金(若手研究(B))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"17K12640","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"item_8_text_65","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"河内, 亮周","creatorNameLang":"ja"},{"creatorName":"Kawachi, Akinori","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-12-21"}],"filename":"2023RP0084.pdf","filesize":[{"value":"92 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://mie-u.repo.nii.ac.jp/record/2000264/files/2023RP0084.pdf"},"version_id":"a358622a-8bd2-467e-93db-d5d1ff2ef4dd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"秘匿計算","subitem_subject_scheme":"Other"},{"subitem_subject":"コミットメントスキーム","subitem_subject_scheme":"Other"},{"subitem_subject":"耐量子計算機暗号","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"計算内在暗号化技術の計算モデル","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"計算内在暗号化技術の計算モデル","subitem_title_language":"ja"},{"subitem_title":"Computational Models in Cryptography for Encrypted Computation","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1701929300332"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-12-21"},"publish_date":"2023-12-21","publish_status":"0","recid":"2000264","relation_version_is_last":true,"title":["計算内在暗号化技術の計算モデル"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-09-24T05:39:20.743183+00:00"}
