SPHINCS+ is a digital signature algorithm that has been standardized by NIST, and it is considered more secure than other digital signatures because it relies solely on the collision resistance of hash functions for its security. However, because it takes more time to compute, hardware acceleration is necessary. The currently adopted parameters include two patterns: SHA2 and SHAKE. By supporting these two hashes, compatibility issues with the communication partner's device can be avoided. A hash design was considered to ensure clock cycles are aligned, preventing the performance of one hash from being compromised.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"DAシンポジウム2024論文集"}],"bibliographicPageStart":"2","bibliographicIssueDates":{"bibliographicIssueDate":"2024-08-21","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2024"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"links":{},"id":238226,"updated":"2025-01-19T08:37:56.108085+00:00"}
