The present invention improves privacy protection and authentication over prior art GAA/GBA system specifying a Bootstrap Server Function (BSF) that creates an Authentication Voucher asserting to a network application function NAF authentication of a. BSF generates keys Ks and Ks NAF with corresponding key identifiers B_TID and B_TID_NAF. In order to prevent tracking of user by collusion between several NAF entities B_TID_NAF and the Voucher can be unique for each NAF. The interface Ua is further protected by encryption using key Ks and the Ub interface is further protected against man-in-the-middle attacks by using signatures with key Ks and provision of freshness.

L'invention apporte des améliorations à la protection de la confidentialité et à l'authentification par rapport au système GAA/GBA de l'art antérieur spécifiant une fonction de serveur d'amorce (BSF) qui crée un justificatif d'authentification définissant l'authentification d'une fonction d'application réseau (NAF). La fonction BSF génère des clés Ks et Ks NAF comprenant des identifiants de clé correspondants B_TID et B_TID_NAF. Afin d'empêcher le suivi d'un utilisateur par collusion entre plusieurs entités NAF, l'identifiant B_TID_NAF et le justificatif peuvent être uniques pour chaque NAF. L'interface Ua est en outre protégée par chiffrement au moyen des clés Ks et l'interface Ub est protégée contre des attaques de type "man-in-the-middle" au moyen de signatures et de clés Ks, et par renouvellement.
