The well-known auction is English auction. This is an auction such that bidders bid up a price, and the highest bidder is determined as the winner when bidding time is over. On the other hand, for selections of order-received constructor of public-works, another type of auction, first-price sealed-bid auction is generally used. In this type of auction, first, each bidder bids for her/his price, and when the bids are opened, the highest(lowest) price bidder is determined as the winner, and gets goods or works at the price for which she/he bids. In this paper, we introduce the current technical trends of electronic first-price sealed-bid auction protocols, using cryptographic techniques for the purpose of keeping bidders' privacy and robustness of the protocols.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電気通信大学"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-0935","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","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":"太田, 和夫","creatorNameLang":"ja"},{"creatorName":"オオタ, カズオ","creatorNameLang":"ja-Kana"},{"creatorName":"Ohta, Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"今井, 識","creatorNameLang":"ja"},{"creatorName":"イマイ, サトル","creatorNameLang":"ja-Kana"},{"creatorName":"Imai, Satoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森田, 光","creatorNameLang":"ja"},{"creatorName":"モリタ, ヒカル","creatorNameLang":"ja-Kana"},{"creatorName":"Morita, Hikaru","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":"2016-11-01"}],"displaytype":"detail","filename":"9000000180.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"9000000180.pdf","url":"https://uec.repo.nii.ac.jp/record/6819/files/9000000180.pdf"},"version_id":"4c142166-b205-4bfc-89d2-2856c5ce206b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"electronic auction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"commitment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hash function","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hash chain","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"public-key cryptosystem","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"電子オークションプロトコルの技術動向 ―第一価格秘密入札プロトコルについて―","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"電子オークションプロトコルの技術動向 ―第一価格秘密入札プロトコルについて―","subitem_title_language":"ja"},{"subitem_title":"Technical Trends of Electronic Auction Protocols －First-price Sealed-bid Auction Protocols－","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["51"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-02-17"},"publish_date":"2010-02-17","publish_status":"0","recid":"6819","relation_version_is_last":true,"title":["電子オークションプロトコルの技術動向 ―第一価格秘密入札プロトコルについて―"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-02-29T01:30:50.662738+00:00"}
