Abstract

We present algorithms for computing the {\it squared} Weil and Tate pairings on an elliptic curve and the {\it 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.
