By exploiting this vulnerability, it is possible to invalidate the encryption of packets sent by the access point, that is, to force plaintext to be sent. This attack method can be applied even if the connection between the client and the access point has already been established, and can pose a serious threat in reality.\n","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"392","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2022論文集"}],"bibliographicPageStart":"386","bibliographicIssueDates":{"bibliographicIssueDate":"2022-10-17","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":223109,"updated":"2025-01-19T13:30:47.197398+00:00","links":{},"created":"2025-01-19T01:22:58.967433+00:00"}
