WebbConfusion and Diffusion According to the famous information theorist Claude Shannon, there are two primitive operations with which strong encryption algorithms can be built: confusion and diffusion are two properties of the operation of a secure cipher identified in 1945 classified report A Mathematical Theory of Cryptography. 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.
