Title (EN) KEY MANAGEMENT SCHEME FOR SECURE COMMUNICATION IN A CELLULAR MOBILE COMMUNICATION SYSTEM
(FR) PROCÉDÉ DE GESTION DE CLÉS POUR LA COMMUNICATION SÉCURISÉE DANS UN SYSTÈME DE COMMUNICATION MOBILE CELLULAIRE
Abstract: front page image
(EN)The present invention is directed to a base station of a cellular mobile communication system, the cellular mobile communication system comprising a communication network for providing a communication session for a plurality of communication terminals of the communication network, the base station comprising a determiner configured to determine whether there is a change of the participants of the communication session; a key provider configured to provide a key to be used for secure communication in the communication session after the change of participants; and a transceiver configured to send to the communication terminals participating in the communication session after the change of the participants a message comprising the key. A method of performing secure communication is also disclosed.
(FR)La présente invention s'applique à une station de base d'un système de communication mobile cellulaire, le système de communication mobile cellulaire comprenant un réseau de communication servant à établir une session de communication pour une pluralité de terminaux de communication du réseau de communication, la station de base comprenant un dispositif de détermination configuré pour déterminer s'il y a eu des changements de participants dans la session de communication ; un dispositif de génération de clés configuré pour générer une clé à utiliser pour la communication sécurisée dans la session de communication après les changements de participants ; et un émetteur/récepteur configuré pour envoyer un message contenant la clé aux terminaux de communication participant à la session de communication après les changements de participants. L'invention concerne également un procédé pour effectuer des communications sécurisées.
