(Trusted Execution Environment)を用いて使用中のデータを保護する，Confidential Computingの利用が進んでいる．我々は，Confidential

Containersなどによってコンテナ基盤に適用するアプローチを示すことで，データサンドボックスの提供する複数主体が利用できるセキュアな実行環境とConfidential

protect data in use by using Trusted Execution Environments (TEEs), the adoption of Confidential Computing is rapidly progressing. We have been conducting research and development on the Data Sandbox that uses Confidential Computing to enable Multi-Party Confidential Computing, where multiple organizations can execute programs while keeping both data and code confidential. However, conventional implementations are based on virtual machines, making it difficult to adopt container-based infrastructures that are widely used in recent service operations. Service providers aiming to offer data sandbox environments have therefore sought improved operational efficiency and compatibility with cloud-native environments. In this study, we propose a new architecture that applies data sandbox components to a container-based infrastructure using technologies such as Confidential Containers. This approach provides both a secure multi-tenant execution environment and native integration with cloud infrastructures, while also enabling consistency verification mechanisms for the container components.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2025-06-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"39","bibliographicVolumeNumber":"2025-CSEC-110"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"id":2002873,"links":{}}
