Reducing the Complexity of the Weil Pairing Computation

Chang-An Zhao and Fangguo Zhang and Dongqing Xie

Abstract: In this paper, we present some new variants based on the Weil pairing for efficient pairing computations. The new pairing variants have the short Miller iteration loop and simple final exponentiation. We then show that computing the proposed pairings is more efficient than computing the Weil pairing. Experimental results for these pairings are also given.
