機器で利用される CPU の 1 つである Arm(R) Cortex(R)-M シリーズが搭載する Trusted Execution Environment 技術である TrustZone(R) をベースに，この機器上のタスクが持つデータを保護し実行する，タスク隔離実行基盤の構築を進めている．本論文では，この隔離実行基盤の設計と実装，機能評価を行ったので報告する．IoT 機器は，小型化や省電力性が求められることから，ハードウェアの制約がある．一方で，スマートウォッチに代表されるようなウェアラブルデバイスでは，個人の生体情報を含むセンシティブなデータを扱い，動的にタスクを追加し実行することいったことも求められる．そこで，TrustZone を用い，Secure World へタスクや関数を動的にロードし，実行を可能にするプラットフォームを提案し，これらの要求を達成するシステムの構築を可能にする．提案システムでは，Non-Secure World を実行主体とし，Secure World 自体を Non-Secure World のタスクの 1 つとしてみなして扱うよう設計している．すなわち，Secure World は，Non-Secure World でスケジューリングされた時にのみ動作する．Secure World 内で動作するタスクや関数のスケジューリングは，Secure World 内に配置されるランタイムにより行われる．これにより，Non-Secure World 側の OS は 1 つのタスクを操作するだけで Secure World を扱い，タスクの隔離実行を実現することができる．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-03-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2022-OS-154"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":217328,"updated":"2025-01-19T15:32:16.403865+00:00","links":{},"created":"2025-01-19T01:17:49.582418+00:00"}
