In this paper, we propose a decentralized identity management scheme based on public-key cryptosystem. We assume that there is a technique to embed some information into a public key of a candidate participant. The information is taken as identity information of a candidate participant and his guarantors as well as a signature that proves the candidate participant certainly knows the corresponding secret key.  Combining the technique with a broadcast mechanism of an updated identity list, we can construct an identity management scheme in a decentralized manner. Such an embedding is realized by the Lenstra's algorithm and its modified variant. We write down concrete parameters and evaluate their sizes.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1080","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2014論文集"}],"bibliographicPageStart":"1073","bibliographicIssueDates":{"bibliographicIssueDate":"2014-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2014"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:50:01.727498+00:00","updated":"2025-01-21T09:25:28.125056+00:00"}
