WebConfusion and diffusion Confusion is focused on changing the symbols from the original message to a different one (for instance, substituting an “a” by a “6”). Notice that when we refer to a message, it can be text, audio, video, images, etc. Diffusion refers to the goal of encrypted symbols not having the same position as the original symbol. Webconditions are directly connected with two basic properties of good ciphers: confusion and diffusion [5]. The aim of confusion phase is to disturb the high correlation among pixels.
