Abstract

Elliptic curve cryptography provides a higher performance than the classic cryptography mainly because shorter keys are used. This paper presents the basics of the elliptic curves, emphasizing the advantage of using them in ecommerce cryptography, this implies a certain level of fields definition for them. We also present several algorithms for scalar multiplication point and for generating strong elliptic curves. Starting from the existing ones, we present an open problem about the weakness of such a systems, in the field of large key computations.
