Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, pairing-based cryptographies such as ID-base cryptography and group signature have been studied.
These cryptographies require exponentiations in multiplicative group $\mathbb{G}_T$. In this paper, the author proposes an efficient exponentiation method for the case of Barreto-Naehrig (BN) curve.
Additionally, the author shows implementation results of the proposed method with conventional techniques such as binary method, window method, NAF method
and Avanzi method. Then, the author shows the proposed method carries out exponentiation fast.
