WebbD'après la définition originale de Shannon, la confusion correspond à une volonté de rendre la relation entre la clé de chiffrement et le texte chiffré la plus complexe possible. La diffusion est une propriété où la redondance statistique dans un texte en clair est dissipée dans les statistiques du texte chiffré.
