(FR) AMÉLIORATIONS DE SÉCURITÉ POUR TRANSMISSIONS DE DONNÉES PRÉCOCES
Abstract:
(EN) A method is provided for use in a wireless device. The method comprises determining (V110) a connection request and uplink data to transmit in response to a random-access response received from a network node. The method further comprises generating (V120) security information based at least in part on the uplink data. The method further comprises transmitting (V130) a radio transmission in response to the random-access response. The radio transmission comprises the connection request and the uplink data secured by the security information.
(FR) L'invention concerne un procédé devant être utilisé dans un dispositif sans fil. Le procédé consiste à : déterminer (V110) une demande de connexion et des données de liaison montante à transmettre en réponse à une réponse d'accès aléatoire reçue d'un nœud de réseau; générer (V120) des informations de sécurité basées au moins en partie sur les données de liaison montante; transmettre (V130) une transmission radio en réponse à la réponse d'accès aléatoire, la transmission radio comprenant la demande de connexion et les données de liaison montante sécurisées par les informations de sécurité.
