This paper presents new explicit formulae for the point doubling , tripling and addition for ordinary Weierstraß elliptic curves with a point of order 3 and their equivalent Hessian curves over finite fields of characteristic three. The cost of basic point operations is lower than that of all previously proposed ones. The new doubling, mixed addition and(More)
In this paper, we present the generalized Huff curves that contain Huff’s model as a special case. First, it is proved that every elliptic curve with three points of order 2 is isomorphic to a generalized Huff curve. Then, the fast and explicit formulae are derived for generalized Huff curves in projective coordinates. This paper also enumerates the number(More)

This paper presents a new model of ordinary elliptic curves with fast arithmetic over field of characteristic two. In addition, we propose two isomorphism maps between new curves and Weierstrass curves. This paper proposes new explicit addition law for new binary curves and prove the addition law corresponds to the usual addition law on Weierstrass curves.(More)
