In 2006, Blake, Murty and Xu proposed three refinements to Miller’s algorithm for computing Weil/Tate pairings. In this paper we extend their work and propose a generalized algorithm, which integrates their first two algorithms. Our approach is to pre-organize the binary representation of the involved integer to the best cases of Blake’s algorithms. Further, our refinement is more suitable for Solinas numbers than theirs. We analyze our algorithm and show that our refinement has better performance than the original algorithms.
