Abstract

Every few years, computer security has to re-invent itself. New technologies and
new application bring new threats, and force us to invent new protection mechanisms.
Cryptography became important when businesses started to build networked computer
systems .The main goal of this work is combining the curve security methods with
cryptography algorithms in order to increase the capability of cryptography. The
weakness of the cryptographic key generated from normal color image is clear due to the
nearest pixel values of image. This led to propose in this paper a new method in order to
generate a cryptographic key depending on generated (2D & 3D) mathematical models
(digital image) and clipping the key according to an algorithm and the data of curve
generation
