Almost perfect nonlinear(APN) functions are one of them. APN functions are classified in EA-equivalent classes. In the study,I consider some permutation group (G, S)where G is the linear group of degree n over GF(2) and S is a set of subspaces of the alternative product of a finite field F with some properties. I proved the number of G-orbits on S equals to the namber of EA equivalent classes of quadratic APN functions on F.I obtained some conditions that a special linear equation over a finite field has exactly two solutions and as a application of the results, I constructed three APN functions and decided subspaces corresponding to these functions up to EA-equivalence. Moreover I obtained an effective expression of APN functions which are equivalent to Gold functions which are most interesting ones among APN functions.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目:基盤研究(C); 研究期間:2011~2014; 課題番号:23540035; 研究分野:代数学; 科研費の分科・細目:","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/d/r/10088403.ja.html"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"NAKAGAWA, Nobuo"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 研究員"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kinki University"}]},"item_8_version_type_12":{"attribute_name":"版","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":"中川, 暢夫"},{"creatorName":"ナカガワ, ノブオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4147","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10088403","nameIdentifierScheme":"研究者番号","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"23540035seika.pdf","filesize":[{"value":"84.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"23540035seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3486/files/23540035seika.pdf"},"version_id":"b175a93c-07de-41cb-b25d-c5fb5d2d3521"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"APN functions","subitem_subject_scheme":"Other"},{"subitem_subject":"finite fields","subitem_subject_scheme":"Other"},{"subitem_subject":"permutation group","subitem_subject_scheme":"Other"},{"subitem_subject":"EA-equivalence","subitem_subject_scheme":"Other"},{"subitem_subject":"plnar functions","subitem_subject_scheme":"Other"},{"subitem_subject":"alternative product","subitem_subject_scheme":"Other"},{"subitem_subject":"cryptography","subitem_subject_scheme":"Other"},{"subitem_subject":"linear equations","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"正則アフィン平面から派生する有限体上の関数の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"正則アフィン平面から派生する有限体上の関数の研究"}]},"item_type_id":"8","owner":"3","path":["2987","2988"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-11-18"},"publish_date":"2015-11-18","publish_status":"0","recid":"3486","relation_version_is_last":true,"title":["正則アフィン平面から派生する有限体上の関数の研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:33:55.162720+00:00"}
