New Addition Operation and Its Application for Scalar Multiplication on Hessian Curves over Prime Fields
Leibo Li and Mingqiang Wang and Zhanjiang Xia
Abstract: In this paper, we present a new addition operation on Hessian curves with low cost.
It can be applied to resist the side channel attacks for scalar multiplication,
and also can be used to compute precomputation points for window-based
scalar multiplication on Hessian curves over prime fields.
We propose two new precomputation schemes
that are shown to achieve the lowest cost among all known methods.
By using the fractional $w$NAF and fractional $wmb$NAF,
if $n=192$ bits and $1I\approx30M$, scheme 1 can save up to $31M$,
scheme 2 can save up to $28M$ with $w\geq 6$, where $I$, $M$ represent
the inversion and the multiplication, respectively.
