This study proposes a novel dynamic ElGamal cryptosystem for encrypted control systems. The proposed cryptosystem is a multiplicative homomorphic cryptosystem, and it updates key pairs and ciphertexts by simple updating rules with modulo operations at every sampling period. Furthermore, the authors modify the proposed cryptosystem by using a dynamic encoder and decoder so that the asymptotic stability of the encrypted control systems is guaranteed. Numerical simulations demonstrate that the encrypted controller with the proposed cryptosystem achieves asymptotic stability while randomly updating key pairs and ciphertexts. The feasibility of the proposed encrypted control system is evaluated through regulation control with a positioning table testbed. The processing time of the proposed encrypted control system is on the order of milliseconds, indicating that the system achieves real-time control.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IET"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1049/iet-cta.2019.0729","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1049/iet-cta.2019.0729","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2021 THE AUTHORS."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"17518644","subitem_source_identifier_type":"ISSN"}]},"item_10001_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":"Teranishi, Kaoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimada, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kogiso, Kiminao","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":"2021-09-27"}],"displaytype":"detail","filename":"iet-cta.2019.0729-4.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","license_note":"CC BY NC ND 3.0","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"iet-cta.2019.0729-4","url":"https://uec.repo.nii.ac.jp/record/10052/files/iet-cta.2019.0729-4.pdf"},"version_id":"abc19851-2164-4b15-a5b4-2a3885cb1e8b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"public key cryptography","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cryptography","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computational complexity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"telecommunication security","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cryptographic protocols","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asymptotic stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stability-guaranteed dynamic ElGamal cryptosystem","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"encrypted control system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"networked control systems","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"multiplicative homomorphic cryptosystem","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asymptotic stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"encrypted controller","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Stability‐guaranteed dynamic ElGamal cryptosystem for encrypted control systems","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Stability‐guaranteed dynamic ElGamal cryptosystem for encrypted control systems","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"13","path":["6"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-09-27"},"publish_date":"2021-09-27","publish_status":"0","recid":"10052","relation_version_is_last":true,"title":["Stability‐guaranteed dynamic ElGamal cryptosystem for encrypted control systems"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-07-21T06:04:42.656402+00:00"}
