A major component to realize Advanced Cryptography is pairing calculations. A high-speed hardware-based pairing implementation using a pipelined Montgomery modular multiplier is available. In addition to pairing, it is also essential to speed up the implementation of MapToPoint function, which maps arbitrary data to points on elliptic curves. We can execute verification process for aggregate signature faster than soflware implementation by calculating MapToPoint function on multiple input signed messages on FPGA using pipelined modular multiplier.","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":"2019-07-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"24","bibliographicVolumeNumber":"2019-SPT-34"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:02:42.862483+00:00","id":198532,"links":{}}
