Generate Cryptographic key using generated 3D- Digital Image


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