However, pairing at the security level equivalent to 128-bit AES keyhas not been implemented in mobile phones without high-level OS such as Windows. The R-ate pairingis one of the fastest pairings over large prime  elds. In this paper, we implement the R-ate pairing at thesecurity level equivalent to 128-bit AES key on BREW mobile phones. Especially, we speed up the  nalexponentiation of pairings using addition chain, and the number of multiplications over a prime  eld canbe reduced by about 8%. As a result, the timing of our implementation of the R-ate pairing on ARM 9225MHz becomes 1.60 seconds, which is comparable to those of RSA and ECC on the same platform.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2009　(CSS2009) 論文集"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-10-12","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2009"}]},"relation_version_is_last":true,"weko_creator_id":"5"},"id":74890,"updated":"2025-01-21T21:26:51.101701+00:00","links":{},"created":"2025-01-18T23:32:14.628098+00:00"}
