Nevertheless, existing methods still have several remaining issues. Among these issues, this paper emphasizes two primary concerns: the absence of validation regarding feasibility and performance for large-scale data and the undue reliance on a Key Management System. To address these challenges, we evaluate the performances of the secure cross-tabulation on the scale of tens of millions and introduce a protocol for Remote Attestation without Key Management System. Furthermore, We discuss the potential of parallelization for further acceleration. Our experimental findings reveal that the secure cross-tabulation on $10^7, 10^8$ can be computed in about 89 hours.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1411","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2023論文集"}],"bibliographicPageStart":"1405","bibliographicIssueDates":{"bibliographicIssueDate":"2023-10-23","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
