Abstract

A key distributor node for a network includes a memory device with at least one first key, at least one data communication device that can exchange data with first and second access nodes for a terminal integrated wirelessly into the network, at least one processor connected to the memory device and the data communication device, wherein functions are provided for the processor(s) that allow authentication of the terminal at the second access node in response to a key request received by the second access node, a derivation of a second key from the first key, and triggered transmission of the second key through the data communication device to the second access node. Connections to the network's first and second access nodes with security relationships can be provided for the key distributor node when using the first key.
