Abstract
Un système et un procédé automatique pour une gestion automatique des clés et des certificats sont décrits. En particulier, une mémoire de clés dans un ordinateur de base contient à la fois de nouvelles et d'anciennes clés cryptographiques. Quand un dispositif de communication mobile doit être mis à jour à l 'aide des nouvelles clés, les nouvelles clés sont automatiquement identifiées en comparant les clés mémorisées dans l'ordinateur de base à une liste de clés précédemment consultées pour déterminer quelles nouvelles clés doivent être marquées pour le téléchargement. Lors du marquage des nouvelles clés, l'utilisateur peut être invité à télécharger les clés nouvellement identifiées, ou elles peuvent être téléchargées automatiquement. Une fois que les nouvelles clés ont été marquées, la liste des clés affichées précédemment est mise à jour pour inclure celles qui sont marquées, de sorte que lorsque la prochaine mise à jour aura lieu, la liste des clés déjà consultées sera correcte.
