For encryption of communication in IoT networks, unicast communication requires the sharing of pair key that is shared between terminals, group communication requires the sharing of group key that is held only by terminals that make up the group, and broadcast communication requires the sharing of global key that is shared by all terminals. Previous research on key-sharing methods has proposed the methods for individual communication types, and there has been no efficient key-sharing method that can be used for all communication types. In this paper, we improve the geometric key sharing scheme for group key sharing and propose a key sharing scheme that can be applied to all types of communication. Furthermore, we compare the proposed scheme with conventional key sharing schemes and show that the proposed scheme is efficient.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1756","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1745","bibliographicIssueDates":{"bibliographicIssueDate":"2022-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"63"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00222724","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"created":"2025-01-19T01:22:46.190543+00:00","updated":"2025-01-19T13:32:51.947326+00:00","id":222833}
