Improved Weil and Tate pairings for elliptic and hyperelliptic curves

Kirsten Eisenträger, Kristin Lauter, and Peter L. Montgomery

Abstract

We present algorithms for computing the squared Weil and Tate pairings on an elliptic curve and the squared Tate pairing for hyperelliptic curves. The squared pairings introduced in this paper have the advantage that our algorithms for evaluating them are deterministic and do not depend on a random choice of points. Our pairings save about 20-30% over the usual pairings.
