Abstract: The need of security for messages transferred between two entities in computer network is a reality. Many algorithms use text key’s with variable length of them. This paper propose an algorithm that use like encoding key a part of an image. For an image with high color definition we have, for every pixel, three values (corresponding to three fundamental colors) that can be mixed in many modes with every byte of the message for encoding them.
