METHODS AND DEVICES HAVING A KEY DISTRIBUTOR FUNCTION FOR IMPROVING THE SPEED AND QUALITY OF A HANDOVER

摘要

Embodiments relate to a key distributer node (AS) for a network, which comprises: a) a memory device (1) with at least one first key, b) at least one data communication device (2) that can exchange data with first and second access nodes (MAP1, MAP2) for a terminal (STA) integrated wirelessly into the network, c) at least one processor (3) connected to the memory device (1) and the data communication device (2), wherein functions are provided for the processor(s) that allow authentication of the terminal (STA) at the second access node (MAP2) in response to a key request received by the second access node (MAP2), d) a derivation of a second key from the first key, and e) triggered transmission of the second key through the data communication device to the second access node (MAP2). Connections to the network's first and second access nodes (MAP1, MAP2) with security relationships are provided for the key distributor node (AS) when using the first key.
