The local area networks (LANs) and radio networks provide broadcast communication at the media access control (MAC) layer, The group communication among multiple entities can be easily realized by these networks. One problem in the broadcast network is how to provide secure communication for the group. In this paper, we discuss how to provide the secure group communication based on the distributed scheme by using less-secure broadcast networks. A group of entities is named a cluster. In the protocol, only and all the entitles in the cluster agree on a same secret key by exchanging the nonce enciphered by the public key. Sometime, a subset of the cluster may require such secure communication that the other entities in the cluster cannot join the communication. In this paper, we discuss how to establish the secure subcluster communication in the cluster.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"122","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"115","bibliographicIssueDates":{"bibliographicIssueDate":"1993-07-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"58(1993-OS-060)","bibliographicVolumeNumber":"1993"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":26288,"updated":"2025-01-22T19:04:36.989063+00:00","links":{},"created":"2025-01-18T22:56:56.999957+00:00"}
