Generate cryptographic key using generated 3d-digital image

الملخص EN

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 and 3D) mathematical models (digital image) and clipping the key according to an algorithm and the data of curve generation.
