Existing evaluations by Dobraunig et al. focused on internal collisions for SipHash-1-x and SipHash-2-x, where the internal processing rounds were reduced to one and two rounds, respectively. In this paper, we extend the search space to provide a more rigorous evaluation of SipHash-1-x and SipHash-2-x, and we also evaluate internal collisions for  SipHash-3-x and SipHash-4-x by using a method involving SAT solvers. Besides, we perform the first security evaluation of forget attacks exploiting tag collisions during the finalization process. As a result, we update existing results on internal collisions and demonstrate that forgery attacks using tag collisions are feasible for SipHash-1-1, SipHash-1-0, and SipHash-2-0. These findings represent the first forgery attacks against SipHash with reduced rounds.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1361","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2024論文集"}],"bibliographicPageStart":"1354","bibliographicIssueDates":{"bibliographicIssueDate":"2024-10-15","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":240927,"updated":"2025-03-06T05:57:11.552142+00:00","links":{}}
