Webb13 apr. 2016 · The Henon map is used for confusion and the Lorenz equation for diffusion. Apart from the Lorenz equation, another matrix with the same size as the original image is generated which is a complex function of the original image. This matrix which is configured as a diffusion matrix permits two stages of diffusion. 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. small sailing cruises caribbean https://victorrussellcosmetics.com
