Abstract

Since many efficient algorithms for implementing pairings have been proposed such as ${\eta}_T$ pairing and the Ate pairing, pairings could be used in constraint devices such as smart cards. However, the secure implementation of pairings has not been thoroughly investigated. In this paper, we investigate the security of ${\eta}_T$ pairing over binary fields in the context of side-channel attacks. We propose efficient and secure ${\eta}_T$ pairing algorithms using randomized projective coordinate systems for computing the pairing.
