Abstract

In this paper, we present a closed formula for the Tate pairing computation for supersingular elliptic curves defined over the binary field $\mathbb F_{2^m}$ of odd dimension. There are exactly three isomorphism classes of supersingular elliptic curves over $\mathbb F_{2^m}$ for odd m and our result is applicable to all these curves.
