Abstract

L'invention concerne un dispositif logique numérique comprenant un circuit de sécurité programmable qui stocke un jeu de clés de sécurité d'autorisation (538) pour la configuration. Le circuit de sécurité compare les clés d'autorisation (360) pour la configuration avec une demande entrante de configuration et effectue par sélection une nouvelle configuration (544) pour le dispositif logique programmable.
