There is an increasing demand for signature schemes using quantum resistant algorithms to prepare for the arrival of quantum computers. However, there are a few issues for application, typically data size. One of the solutions to this issue is the aggregate signature which gathers multiple signatures into one and make the data size smaller. However, the aggregation method has not been established for lattice-based signature schemes. In this paper, we propose a lattice-based signature aggregation method using Chinese remainder theorem, prove its correctness and examine the application on an existing NTRU lattice-based signature scheme.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-11-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2021-SPT-45"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":213570,"updated":"2025-01-19T17:06:53.767463+00:00","links":{},"created":"2025-01-19T01:14:26.293054+00:00"}
