Des valeurs de séquence, calculées en fonction des données secrètes, sont ajoutées aux mises à jour envoyées du noeud mobile vers le noeud correspondant et sont utilisées par le noeud correspondant afin d'authentifier les mises à jour issues du noeud mobile. Une adresse local du noeud mobile n'est pas ouvertement divulguée. Une adresse temporaire prévue est calculée au niveau du noeud correspondant et utilisée par le noeud correspondant afin d'envoyer des paquets de données au noeud mobile.
