Transport Layer Security (TLS) protocols have been designed only for communication between exactly two hosts, and thus, they cannot provide security in the cases that middleboxes require permission to read and write plaintext data. Several studies have designed protocols to provide security for such communication, however, they have the following problems: Requirements for protocols have not been systematically organized. They assume only the case that all hosts and middleboxes are honest. Therefore, if one of the hosts and middleboxes is compromised by an adversary, security of the session can completely be compromised. In this paper, we organize the requirements proposed in existing studies and design a protocol in which an adversary can only cause minimal impacts on security of a session even if the adversary compromises any of the hosts and middleboxes in the session.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"162","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2021論文集"}],"bibliographicPageStart":"155","bibliographicIssueDates":{"bibliographicIssueDate":"2021-10-19","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T16:38:21.433252+00:00","created":"2025-01-19T01:15:14.301358+00:00","links":{},"id":214421}
