Lorsque nous discutons de sécurité et de réseaux, nous ne nous souvenons jamais de la contribution des méthodes et techniques de cryptage et de décryptage. Depuis quelques années, l'informatique à ADN est une technologie en plein essor qui peut apporter sa contribution à diverses méthodes d'informatique douce et à des algorithmes de sécurité.Il y a beaucoup d'efforts et de propositions dans la recherche d'algorithmes efficaces, efficients et robustes pour le cryptage d'images. Dans ce projet, nous travaillons sur une technique de cryptage d'images en utilisant la technique d'ajout de séquences d'ADN. La technique proposée Tout d'abord, l'image est convertie en matrice binaire après avoir été divisée en blocs égaux. Deuxièmement, chaque bloc est codé en séquences d'ADN et l'opération d'addition de séquences d'ADN est utilisée pour ajouter ces blocs. Troisièmement, on effectue l'opération de complément de séquence d'ADN pour le résultat d'une matrice ajoutée en utilisant deux cartes logistiques. Enfin, en décodant la matrice de séquences d'ADN obtenue lors de la troisième étape, nous obtiendrons l'image cryptée. Les résultats expérimentaux de la simulation et l'analyse de sécurité montrent que notre algorithme peut non seulement obtenir un meilleur effet de cryptage, mais aussi résister aux attaques exhaustives, statistiques et différentielles.
