However, pairings at the security level equivalent to 128-bit AES key have not been implemented in mobile phones without a high-level OS such as Windows. The R-ate pairing is one of the fastest pairings over large prime fields. In this study, we implemented the R-ate pairing at the security level equivalent to 128-bit AES key on BREW mobile phones. We compared the processing time of the R-ate pairing with those of the Ate pairing and ηT pairing. In the results, the R-ate pairing was fastest pairing. Also, we compared the processing time of pairings with those of RSA and ECC on ARM9 225MHz. In the result, the processing time of the R-ate pairing was similar those of RSA and ECC."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004230670823941","@type":"Researcher","foaf:name":[{"@value":"Tadashi
