However, along with end-to-end encryption, WEP and WPA have large overhead due to duplicated encryption. In this paper, we propose a method to reduce this drawback. On this method, a wireless client can choose packet encryption or packet authentication in its wireless LAN automatically depending on whether end-to-end encryption is performed or not. With packet authentication in case that end-to-end encryption is performed, we can improve the communication speed on the wireless environment while preventing invalid access.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1080","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1072","bibliographicIssueDates":{"bibliographicIssueDate":"2008-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"49"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"Internet/LAN 運用管理技術"}]},"weko_creator_id":"1"},"id":9606,"updated":"2025-01-23T03:18:00.408563+00:00","links":{},"created":"2025-01-18T22:44:46.650718+00:00"}
