DESede est un algorithme de chiffrement symétrique issu de l'amélioration de l'algorithme de chiffrement symétrique DES. Il s'agit d'un mécanisme qui chiffre les données trois fois à l'aide d'une clé de 168 bits ; il offre généralement (mais pas toujours) une sécurité extrêmement robuste. Si les trois sous-éléments de 56 bits sont identiques, le triple DES reste rétrocompatible avec DES. Des améliorations ont été apportées aux problèmes de longueur de clé trop courte et de nombre d'itérations insuffisant de l'algorithme DES, renforçant ainsi la sécurité. Cependant, la lenteur de traitement de l'algorithme DESede, le temps de calcul de clé relativement long et la faible efficacité de chiffrement rendent le développement des algorithmes de chiffrement symétrique peu optimiste.
