Abstract
In this paper, we introduce the concept of an optimal pairing, which by definition can be computed using only log 2 r/¿(k) basic Miller iterations, with r the order of the groups involved and k the embedding degree. We describe an algorithm to construct optimal ate pairings on all parametrized families of pairing friendly elliptic curves. Finally, we conjecture that any nondegenerate pairing on an elliptic curve without efficiently computable endomorphisms different from powers of Frobenius requires at least log 2 r/¿(k) basic Miller iterations.
