Abstract
Scalar multiplication is the back-bone operation in the elliptic curve cryptosystem. Quad-and-add algorithm replaced the traditional double-and-add algorithm to compute the scalar multiplication. In this paper, we introduce the method of utilizing the point quadruple scalar operation in the elliptic curve cryptosystem. Induced expressions were applied to real cryptosystem and proven at C language level. Point quadruple operation can be utilized to fast and efficient computation in the elliptic curve cryptosystem.
