基于半点和多基表示的标量乘法扩展算法
Extended Algorithm for Scalar Multiplication Based on Point Halving and MBNS
摘要
Abstract
This paper proposes a representation ora scalar k in the form of d(1/2)a3b5c , where d belongs to a given digit set.This representation is a combination of the point halving and MBNS representation using the method of Extended DBNS.A scalar multiplication relying on the representation is given.Experimental results show that the approach leads to a shorter MBNS expansion and a lower complexity in elliptic curve scalar multiplication at the cost of a few pre-computations and storages.关键词
