Le PEPR Cloud a pr\u00e9sent\u00e9 de nouvelles attaques par inf\u00e9rence d&rsquo;attributs (AIA) sp\u00e9cifiquement con\u00e7ues pour les t\u00e2ches de r\u00e9gression. Ces AIA consid\u00e8rent des sc\u00e9narios o\u00f9 les adversaires peuvent espionner les messages \u00e9chang\u00e9s ou interf\u00e9rer directement avec le processus de formation.<\/p>\n\n\n\n<p>Les r\u00e9sultats montrent une augmentation significative de la pr\u00e9cision de la reconstruction, particuli\u00e8rement dans les ensembles de donn\u00e9es clients h\u00e9t\u00e9rog\u00e8nes.
