COTS（Commercial-Off-The-Shelf）ハードウェアで中央装置を多重化し，さらに，制御処理に時間的冗長性を導入した手法を提案している．本研究では，この提案手法にサイバー攻撃への対策を追加することを検討する．サイバー攻撃に対しては，メッセージの真正性や完全性を検証することが有効とされており，提案手法でも，それらの対策は実施される想定である．しかし，COTS では OS 等の脆弱性を悪用される可能性があり，それによって中央装置が乗っ取られた場合には，サイバー攻撃への対策が無効化されることを想定する必要がある．そこで本研究では，乗っ取りが発生した場合でも，多重化した中央装置の過半数未満の乗っ取りであれば，安全性を確保することが可能な二つの対策手法を提案する．これらの対策手法において，実際に中央装置で乗っ取りが発生した場合の耐性をシミュレーションによって評価した．また，それらの手法の耐故障性を確認するために，乗っ取りがなく，通信ネットワークの伝送断だけが発生した場合の評価もシミュレーションした．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告システム・アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-05-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2023-ARC-253"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
