Crypto-Agility を有した耐量子計算暗号に対応できるようにすること,の 2 点を目指し,システム構成の検討を行う.具体的には,低レイヤー暗号通信として MACsec を利用し,MACsec で耐量子セキュリティを実現するために,暗号通信機能と認証・鍵交換機能を分離して構成した.そのうえで,クラッキングやマルウェアによって通信データが漏洩しないようにどの機能を同じ TEE 領域で処理するべきかを明らかにし,コンテナ環境上でのシステム例を構成した.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ(CSEC)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-03-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"58","bibliographicVolumeNumber":"2024-CSEC-104"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":233272,"updated":"2025-01-19T10:09:07.639603+00:00","links":{},"created":"2025-01-19T01:34:36.892442+00:00"}
