Abstract

In this paper the way to communicate over a network by two parties, how to agree on a symmetrical encryption and how a cryptographic key is created will be discussed. The paper review a new proposed method, starting from sharing a common information. The di�erence reside in the way the information is combined inside the original image. Starting from the classic form of hiding information in a particular and characteristic image, a speci�c message will be hidden in a 3D natural environment scene. The 3D scene is generated using a grayscale height map (for terrain generation) and a Lindenmayer system (for the generation of plants). It is intended to include the common information inside a layer part of a multilayer image.
