Abstract[English]
Various aspects of the present disclosure relate to methods, apparatuses, and systems that support key for connectivity to a cell group. For instance, implementations provide ways for a UE to securely switch connectivity from a first SCG associated with a master cell group (MCG) to a second SCG associated with the MCG. The UE, for example, has previously connected to (e.g., visited) the second SCG. The UE informs the MCG of the upcoming connectivity switch. Accordingly, the MCG uses a security counter value to generate a new secondary key and the MCG transmits the security counter value to the UE. Further, the MCG transmits the new secondary key to the second SCG. Thus, the UE can generate the secondary key using the security counter value and the UE and the second SCG can transmit and receive data using the secondary key.[French]
Divers aspects de la présente divulgation concernent des procédés, des appareils et des systèmes qui prennent en charge une clé pour une connectivité à un groupe de cellules. Par exemple, des mises en œuvre fournissent des moyens à un UE de commuter de manière sécurisée la connectivité d'un premier SCG associé à un groupe de cellules principal (MCG) à un second SCG associé au MCG. L'UE, par exemple, s'est précédemment connecté au second SCG (par exemple, l'a visité). L'UE informe le MCG de la commutation de connectivité à venir. Par conséquent, le MCG utilise une valeur de compteur de sécurité pour générer une nouvelle clé secondaire et le MCG transmet la valeur de compteur de sécurité à l'UE. En outre, le MCG transmet la nouvelle clé secondaire au second SCG. Ainsi, l'UE peut générer la clé secondaire à l'aide de la valeur de compteur de sécurité et de l'UE et le second SCG peut transmettre et recevoir des données à l'aide de la clé secondaire.
