address information leaks caused by administrative errors or mishandling, a function for tracing the diffusion of classified information using a virtual machine monitor (VMM) was proposed. However, the proposed function does not support the case where virtual machines (VMs) allocated to multiple virtual central processing units (vCPUs) are to be monitored. In addition, it does not support the case where multiple VMs are monitored simultaneously. In environments such as cloud computing, this issue needs to be addressed because VMs allocated to multiple vCPUs may run concurrently on a VMM. Therefore, in this study, we describe how to deal with VMs allocated by multiple vCPUs. We also show how to deal with multiple VMs. Furthermore, we report the evaluation results for assessing the traceability of the improved proposed method and its overhead.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1409","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1398","bibliographicIssueDates":{"bibliographicIssueDate":"2022-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"63"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00220078","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"created":"2025-01-19T01:20:14.010355+00:00","updated":"2025-01-19T13:55:56.206745+00:00"}
