In this paper, we propose three ideas to speed up the computation of the group operation in the Jacobian of a hyperelliptic curve:1Division of polynomials without inversions in the base field, and an extended gcd algorithm which uses only one inversion in the base field.2The omission of superfluous calculations in the reduction part.3Expressing points on the Jacobian in a slightly different form.
