Powered Tate Pairing Computation

Bo Gyeong Kang and Je Hong Park

Abstract: In this paper, we introduce a powered Tate pairing on a supersingular elliptic curve that has the same shortened loop as the modified Tate pairing using the eta pairing approach by Barreto et al. The main significance of our approach is to remove the condition which the latter should rely on. It implies that our method is simpler and potentially general than the eta pairing approach, although they are equivalent in most practical cases.
