However, identity-based matchmaking encryption (IB-ME) requires an authority called a key generation center (KGC) to generate keys for all users, which is computationally expensive. In this paper, we propose hierarchical identity-based matchmaking encryption (HIB-ME) that can re- duce the burden of the (single) KGC, such as key generation for all users. Specifically, we define the notion and its required security of HIB-ME and give its generic construction. Furthermore, we show how to upgrade a chosen plaintext secure HIB-ME scheme into a chosen ciphertext secure one.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-07-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"30","bibliographicVolumeNumber":"2023-CSEC-102"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:26:17.189182+00:00","updated":"2025-01-19T12:19:17.174451+00:00","id":226967}
