摘要： Techniques for the secure generation of a set of encryption keys to be used for communication between a wireless terminal and an assisting base station in a dual-connectivity scenario. An example method includes generating (810) an assisting security key for the assisting base station, based on an anchor base station key. The generated assisting security key is sent (820) to the assisting base station, for use by the assisting base station in encrypting data traffic sent to the wireless terminal or in generating one or more additional assisting security keys for encrypting data traffic sent to the wireless terminal while the wireless terminal is dually connected to the anchor base station and the assisting base station. The anchor base station key, or a key derived from the anchor base station key, is used (830) for encrypting data sent to the wireless terminal by the anchor base station.

摘要： A wireless local area network, WLAN, node (400) is adapted to be comprised in an integrated wireless communications network comprising a WLAN and a cellular communications network. The WLAN node (400) comprises a receiving module (401) adapted to receive traffic data signals from a wireless device. A security module (403) is adapted to process the received traffic data signals and apply a first security protocol to a first traffic data signal received from the wireless device and a second security protocol to a second traffic data signal received from the wireless device. A routing module (405) is adapted to route the first traffic data signal to a node of the cellular communications network and route the second traffic data signal to a node of the WLAN. In one example the the security module is adapted to concurrently process the first traffic data signal and second traffic data signal from the wireless device, and the routing module (405) is adapted to concurrently route the first traffic data signal and the second traffic data signal to their respective nodes.
