When this scheme is applied to preservation of secret key in public key cryptography, there is a risk of the reconstructed secret key being stolen. To overcome such a drawback, a (k,n) threshold based encoding scheme for ElGamal encryption system has been proposed. In this work, we developed a threshold decoding system for ElGamal encryption using NFC (Near Field Communication). The developed system distributes secret keys of ElGamal cryptographic system to NFC devices such as IC cards and Android smartphones using (k,n) threshold scheme. We confirmed that the developed system can decode cryptograms without reconstructing the secret key.","subitem_description_type":"Abstract"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2434-3709","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大村 , 光德"},{"creatorName":"Omura, Kotoku","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮崎 , 真一郎"},{"creatorName":"Miyazaki, Shinichiro","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松嶋 , 智子"},{"creatorName":"Matsushima, Tomoko K.","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山嵜 , 彰一郎"},{"creatorName":"Yamasaki, Shoichiro","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Omura, Kotoku","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyazaki, Shinichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsushima, Tomoko K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamasaki, Shoichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-08-07"}],"displaytype":"detail","filename":"6 論文 Vol.36No.1.R.P18-P26.pdf","filesize":[{"value":"733.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"【論文】NFCを用いたElGamal暗号しきい値復号システムの開発","url":"https://ptu.repo.nii.ac.jp/record/66/files/6 論文 Vol.36No.1.R.P18-P26.pdf"},"version_id":"9e27a689-be48-40cf-b4e8-0a115881db5f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ElGamal cryptographic system, (k,n) threshold scheme","subitem_subject_scheme":"Other"},{"subitem_subject":"Near Field Communication","subitem_subject_scheme":"Other"},{"subitem_subject":"Android","subitem_subject_scheme":"Other"},{"subitem_subject":"ElGamal cryptographic system, (k,n) threshold scheme","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Near Field Communication","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Android","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"【論文】NFCを用いたElGamal暗号しきい値復号システムの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"【論文】NFCを用いたElGamal暗号しきい値復号システムの開発","subitem_title_language":"ja"},{"subitem_title":"Development of a Threshold Decoding System for ElGamal Encryption Using NFC","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"6","path":["26"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-08-07"},"publish_date":"2020-08-07","publish_status":"0","recid":"66","relation_version_is_last":true,"title":["【論文】NFCを用いたElGamal暗号しきい値復号システムの開発"],"weko_creator_id":"6","weko_shared_id":-1},"updated":"2023-06-22T02:59:58.689033+00:00"}
