Speeding up Computation of Scalar Multiplication in Elliptic Curve Cryptosystem
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 4
Abstract
The basic operation in elliptic curve cryptosystem is scalar ultiplication. It is the computation of integer multiple of a given point on the curve. Computation of scalar multiple is faster by using igned binary representation as compared to binary epresentation. In this paper ‘Direct Recoding Method’ a new modified algorithm for computation of signed binary epresentation is proposed. Our proposed method is efficient when compared to other standard methods such as NAF, MOF and complementary recoding method.
