This network has a problem in which encryption keys on all the nodes in a cluster reveals, if the cluster head (CH) which manages all nodes in a cluster and communicates with a base station is analyzed. On the other hand, when all the nodes may be set to CH, the problem that comparatively big storage capacity must be given to all the nodes arises to hold the key of all the nodes in a cluster. In this paper, we propose the first key sharing scheme which carries out key sharing with CH and all the nodes in a cluster, and realize the information theoretical security using secret sharing scheme, even if CHs are analyzed. In addition, we propose the second key sharing scheme in which storage capacity for CH to save the key on each node in a cluster is not needed. In order to realize it, secret sharing scheme is improved and the security is evaluated. In the last, we show the third key sharing scheme which reveals no key, even if CH or all nodes except CH are analyzed.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2249","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2236","bibliographicIssueDates":{"bibliographicIssueDate":"2016-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"57"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":175053,"links":{}}
